Title: Free Ektar 100 LUT for Magic Lantern footage
Post by: hyalinejim on April 06, 2017, 04:43:09 AM
We all know that one of the advantages of shooting RAW is the scope it gives to achieve different looks. LUT solutions such as FilmConvert, Koji and Impulz attempt to emulate popular film stocks with more or less success for different cameras. Part of the problem of using these LUTs for Magic Lantern footage is that it's not always entirely clear how best to prepare the footage before the LUT.

A while back I became very interested in generating my own LUTs. It started with my efforts to match an XC10 to Magic Lantern tonality and colour. I used a ColorChecker and Resolve to get a pretty close match between the two. More recently I've begun searching online for photos of ColorCheckers taken on photographic film. I wanted to share a LUT I made to emulate a particular (scanned) shot taken on Ektar 100 that I found at http://lifeindigitalfilm.blogspot.ie/2009/07/film-review-kodak-ektar-100-135-format.html (http://lifeindigitalfilm.blogspot.ie/2009/07/film-review-kodak-ektar-100-135-format.html)

This has a nice gentle curve and pastel colours - good for blues and pinks. If you can tweak your white balance at the perfect point on the blue-orange and green-magenta axes, the results can be really nice for skin tones. Here's the LUT:

https://drive.google.com/open?id=0B1exEpCRAfgFZ2drM1JWYmdSY28

This is optimised for my workflow, which means Cinelog-C for Adobe Camera Raw. But if you don't have Cinelog for ACR or Resolve you can still use the LUT if you can get your footage into a log gamma. In Resolve color management settings, choose Arri Log C Timeline Colorspace for results very close to Cinelog.

The LUT is very friendly towards footage prepared in this way. There should be no clipping of the highs or lows. All you need to do is set the black point and white point, fine tune white balance and tint and you're good to go. I find that this order works best:

Curves
White balance
LUT

Magic Lantern has given me a lot over the years. This is one small way in which I can give back to the community.

Glad people are enjoying the lut! I had some time this evening to do more tinkering. There are a number of good shots of Colorcheckers using various stocks at this link:

http://125px.com/articles/photography/film/kodak-film-comp/

With one of these shots I've created a slightly different version of the Ektar 100 lut, giving a different colour response. I kept the gamma the same as the first one, as I think it works really well, and the white balance is matched between them.

Here's the download:

https://drive.google.com/open?id=0B1exEpCRAfgFUTZVTHpKR0FScUE

I'm calling this LANDSCAPE simply because the greens are far more accurate and life-like in this version, while maintaining the rosy pastel hues. That doesn't mean the first lut is obsolete - it's just different. It also doesn't mean that this second lut is only good for landscapes - skin looks great too - I'm just calling it that because greens are actually really muddy brown in the first lut. Also this one is more saturated.

Here are samples of the new ML Cinelog-C to Ektar 100 LANDSCAPE lut:

Have a play with the lut and let me know what you think! There are other film stocks that could be emulated on that page above. I'm off on my hols for two weeks, though. I'll do a few more when I get back.

So, I've tested it and that's good. I think it's too contrasted and too saturated, but that's probably just a personal opinion.
I also compared it against other luts that emulate Ektar:

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fa.cocaine.ninja%2Fglbuch.gif&hash=0f75c630893c4154db0d030056766ad3)
Title: Re: Free Ektar 100 LUT for Magic Lantern footage
Post by: hyalinejim on April 07, 2017, 05:23:10 PM
Yes, the reds are definitely very hot in my landscape lut, and if there is a lot of shadow noise (like you get from Resolve's debayering) the lut will accentuate that unless you desaturate the shadows after the lut. However, it shouldn't be giving you results that are too contrasty. Are you sure that the input is Cinelog-C or something similar?

Here's a high contrast scene with highlight clipping, Cinelog-C ACR profile in a Rec709 After Effects project:

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs28.postimg.org%2Fu7g5kolb1%2Frodney_0-00-00-14.jpg&hash=b12586d18423390acd5fcded6b86e03c) (https://postimg.org/image/5e6lk12ah/)

Here it is with Ektar 100 Landscape. Highlights are now just under 100 IRE and shadows are sitting at 0 but not clipped too much.

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs28.postimg.org%2Fjynoeux99%2Frodney_0-00-00-14_1.jpg&hash=6c1fa1e81744f53f05b3869181500347) (https://postimg.org/image/grt4v8ct5/)

So it's quite a mild contrast boost. Thanks for the comparison to other Ektar luts - that's really interesting! Of course each emulation depends on the condition of the film, the processing and the scanning, as well as the emulation technique. I've found another interesting looking Ektar 100 colour chart, this time with very purply blues. I'll give this a go when I get back from hols.

https://www.photo.net/discuss/threads/ektar-100-vs-ektar-25-grain.348393/

In the meantime, here are some more examples, mainly in mixed lighting (output from Resolve, so shadows might be a bit noisy)

Very nice work @hyalinejim.

Im a big user of Koji Color LUTS, but now i think to use your. More easy to grade with it, more neutral. The shadows are less crushed too.

I'm sure. In my test I gave rawtherapee the input, the loaded the DCP, fixed WB and exposure, and exported in TIF 16bit. Then imported on photoshop and gave it the lut.
Maybe if you decrease the cyan/blue light value by 40% it would be nice. Also, maybe decrease neutral saturation by -30%, and decrease overall saturation by 15%. Also less crushed shadows, upping the zone 3 by ~20%.

What is the software you're using to do it?

Adobe Camera Raw to After Effects, and this is what the lut is optimised for. Maybe that's why it's too contrasty on your end. If you have Cinelog-C and After Effects you can try this (from the Cinelog-C 2017 user guide):

Quote
Open After Effects and create a new composition

Open the Project Settings panel and set Depth to 32 bits per channel (float). Working Space should be set to HDTV (Rec.709). Compensate for Scene-referred profiles should be ticked. Linearize Workspace, Blend colors using 1.0 gamma and Match legacy After Effects QuickTime Gamma Adjustment should be unticked (no tick). Other settings should remain at their defaults.

Click on OK.

Important: The Cinelog Digital Camera Profiles and OpenColorIO configuration are mathematical and calculations are based strictly on a defined standard. The Working Space ICC profile should always be set to HDTV (Rec.709) when using Cinelog for accuracy.

In Adobe Camera Raw:

Select the Camera Calibration tab (camera icon) and choose the Cinelog-C camera profile for your camera.

If you don't have Cinelog or After Effects, DNGs debayered into an Alexa Log C timeline in Resolve should be more or less similar.

You can see from my earlier before and after shots of the backlit mountain that shadows shouldn't be crushed too much by the lut. So there must be something about the Raw Therapee to PS workflow that gives different input levels than what the lut is expecting. If so, it's easy to raise and lower black points before the lut.

Out of curiousity, why are you using Raw Therapee with Photoshop, when Adobe Camera Raw comes bundled with Photoshop?

I'm just using PS to apply the lut, I don't really use PS at all (unless I need to manipulate an image in a physical way, like remove some object). I use rawtherapee because it's the most advanced raw processor I know, and I've tried many.
Rawtherapee has the support to apply lut, but just Hald CLUT, not 3dLut. I need yet to convert the luts I use to Hald CLUT to use it directly without photoshop.
I'm actually planning to do all the work with rawtherapee on a MLV project I have, and then just glue everything with kdenlive, so I can keep it all open source...

Thanks for the DNG via PM! Here's what your DNG looks like in a Rec 709 After Effects project, using Cinelog-C profile via ACR:

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs8.postimg.org%2Fa0bsw1wth%2Fpflhln_Cinelog-_C.jpg&hash=569a681fefab57d17a39e59d6dfb8722) (https://postimg.org/image/nu05l3pep/)

And this is with the landscape lut applied:

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs8.postimg.org%2Fyi3wjxzdx%2Fpflhln_Ektar_Landscape_default.jpg&hash=ed53bc50bbeec7da2911f3b72e8151a2) (https://postimg.org/image/rrnfaic81/)

Now, it's a high dynamic range scene and you've protected the highlights. So I simply added a curve before the lut and lifted the middle quite a bit, and lowered the black point slightly to compensate:

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs8.postimg.org%2Fua94b6xyd%2Fpflhln_Ektar_Landscape_lifted.jpg&hash=0579e269f4752c5e644d6981303f2a45) (https://postimg.org/image/r3ekrkdi9/)

Highlights are preserved, the texture of the tablecloth is preserved in the shadow areas (if you zoom in on a calibrated monitor). The colours are not too saturated, and the red of the anamorphic clamp looks a lot more natural than in the gif you posted above.

Maybe the Cinelog DCP doesn't behave the same in Raw Therapee as it does in ACR?

Hey I honestly am digging this Ektar 100 LUT in conjuction with Cinelog DCP which mates really well together and thanks for sticking with the ACR route within AE. Love how the shadows are coming out from this combo. Feels very authentic and yet not too filmic! Nice job on nailing down the gamma!

May be... still, in your editing I still see crushed shadows. I should not occur since it's an HDR image. But, the image I've sent you is crap, I'll do some landscape next week to test it properly.

Hey @DeafEyeJedi , dual_iso and a polarizer would help in this kind of scenes ;)
But it still quite good. Good job!

In case anybody didn't already know, multiprocessing was disabled in AE CC 2015. Render times are way faster in CC 2014 and CS6. CS6 is a bit faster than CC 2014 on my 6 core Mac Pro. Installers are still available through creative cloud.

@DeafEyeJedi great to see the lut being put to good use! The difference with ACR defaults is striking. Might use this for photos as well.

ACR definitely has best debayering but if I'm in a rush I use Cinelog for Resolve.

Way faster, depends how many cores you have. Rendering is CPU based in AE. CS6 and CC 2014 make use of virtual cores, so on my mac I allocate 10 cores to rendering. I've allocated 2Gb of ram per core but it doesn't need that much to run at optimum speed. Edit>Purge>All memory and [caps lock] to disable screen refresh speeds up rendering too.

@DeafEyeJedi I think it should have more ~0.7 f-stop on your scene, it seems a but underexposed... maybe the highlights will be overexposed after the 0.7 increase, so perhaps compress the highlight. Does it still generate flickering on ACR? You see, Rawtherapee has no problem with that :P

I dont know what I do wrong,
but mny output is far away from what you guys show off :D

I tried to:

Import cDNG into Resolve -> timeline Alexa C-Log -> LUT -> way to yellow image
Import cDng to ACR -> bmd camera setup (payed converter) -> save as tif -> import to resolve -> LUT -> way to dark image
Import cDng to ACR -> VisionLog Camera Settings -> save as tif - import to resolve -> LUT -> kinda ok developed, but not near to the look you show

any idea?

thanks, Jan

He writes the lut is for Cinelog-c, if you dont have cinelog-c then Log-C is the closest. Add some saturation and increase exposure or vice versa. Cinelog-c is made to resemble Log-C so you can get good results with the lut. But to get a more natural look, you could change the hue on the green. The Ektar film has a lot of Yellow bias in the greens its the way its supposed to look.
Title: Re: Free Ektar 100 LUT for Magic Lantern footage
Post by: hyalinejim on April 14, 2017, 01:38:26 AM
For this lut (and generally any look lut) you need to adjust white balance and exposure before the lut.

So if things are too yellow, lower the colour temperature. Too magenta, change the tint. Underexposed, raise the exposure (I like curves for this one as you can quickly set whites, blacks and midtones). Too saturated, lower the saturation.

These are best done before the lut, but you can try some of them after the lut as well.


Import cDNG into Resolve -> timeline Alexa C-Log -> LUT -> way to yellow image

Import cDng to ACR -> bmd camera setup (payed converter) -> save as tif -> import to resolve -> LUT -> way to dark image
Import cDng to ACR -> VisionLog Camera Settings -> save as tif - import to resolve -> LUT -> kinda ok developed, but not near to the look you show


For Resolve, try a different white balance.

For ACR, forget VisionLog and BMDFilm - you need Cinelog C here. It's not so expensive. The combo of ACR (best debayering) and Cinelog C (retain all dynamic range, keep noise under control and play nicely with Alexa luts) is a winner as far as I'm concerned. But if I'm short on time I use Resolve.

Thanks to everyone for trying this out. For those who are digging it I'll make more soon. I'm in Bali at the moment on holidays. The light is amazing. I brought my XC10 and just befire I left I made an Ektar lut for that as well. It totally brings the XC10's colour to a new level.

For this lut (and generally any look lut) you need to adjust white balance and exposure before the lut.

Agreed.

Quote
So if things are too yellow, lower the colour temperature. Too magenta, change the tint. Underexposed, raise the exposure (I like curves for this one as you can quickly set whites, blacks and midtones). Too saturated, lower the saturation.

Took me awhile to figure out why things were slightly yellow during my early days of using Cinelog-C few years ago (even tho I had set the Kelvin's the way I like from how it looks by double checking in ACR color profiles to CinelogRec709 temporarily for WB correction if needed).

However, Curves are the way to go when it comes to exposures along w the whites, blacks & midtones without creating flickering in post.

ACR + Cinelog DCP is the mother combo of all and always has been. Cinelog DCP 2017 hasn't been updated yet for Resolve but w the previous version works just fine when timing is tight for quick turnarounds.

It is definitely noticeable differences in quality between those two algorithms though. Even at ProRes4444XQ. There are reasons why ACR takes longer.  :D

Hi everybody who's enjoying the Ektar lut. I've made a new version that I've called TWISTED:

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs9.postimg.org%2Ftowf62sof%2FOPS_1-26-28-13.jpg&hash=041c15d07c4f7f5e807a74edf02aca84)

Link is here:

Why is it twisted? Not because it's morally deviant, like you. But because there's a subtle hue twist from shadows to midtones to highlights which more accurately models the colour rendition of some of those Ektar scans I found.

In real terms it's subtle and doesn't make a huge difference, but the effect is there. What you will notice, however, compared to the previous LANDSCAPE lut, is that blues are more vivid and reds are ever so slightly less hot. Greens are still psychologically accurate. Also, when you first apply it, the white balance is more neutral - previous versions were skewed towards pink because that's the effect I was trying to recreate. You can still get the pinky pastel look with this version by manipulating tint before the lut. Have fun!

This LUT is the best I've ever tried with ML raw. Gonna use this a lot, thanks so much for sharing!  8) :)

Saw your vid from the Berlinale talks - looks great!

Question about using Arri Log C as your timeline display LUT w/ Resolve - when I go to export files that I've graded this way, the timeline display LUT isn't baked in to the exported image. So I get washed out colors and so on, very different from what was in Resolve. Note I'm not talking about the usual prores gamma shift, it's literally just not applying the first of the two LUTs on export. Is there an option on export I need to flag?

Very cool LUT by the way, using it on some 5d3 3K stuff right now and it's very nice.

Ok. Here's the Ektar lut of all luts, the Mother LUT if you will. I'm calling this one ADVANCED:

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs12.postimg.org%2F924ebfprx%2FComp_1_0-00-00-16_1.jpg&hash=98955445896c0fde55bc24ceeaf8a6af)

(Images sourced at kleptography because I'm bored of using my own....   http://www.kleptography.com/dl/5diii/raw/)

Download ADVANCED lut here:

https://drive.google.com/open?id=0B1exEpCRAfgFbTBFMkdzZHdTVEU

So what's different about this one? The colour is the same as TWISTED but instead of using a nice, user friendly gamma curve this lut accurately emulates the complex curve of the Ektar scans I found, including how contrast is altered when the exposure is pushed or pulled. This means that it takes a little more work on your part to get a good looking image. When you first apply the lut you probably won't get a nice result - it's very contrasty and may be severely over or under exposed. Think of the lut as part of the development process rather than an end in its own right. I recommend this order of operations:

1. White balance (temperature and tint)

2. Pre Curves - try raising and lowering white and black points and midtones to reveal the tonal information or contrast profile you're interested in. Watch the waveform and notice how contrast and colour shifts at different IRE levels. It might be necessary to over or under "expose" at this stage, or even to send a very low contrast input into the lut - just as you might push or pull an exposure when developing film. Be creative here.

3. ML Cinelog-C to Ektar 100 ADVANCED lut

4. Post Curves - now use curves again to correctly set blacks, whites and midtones.

5. Saturation - this version has a lower saturation than previous versions, so you might want to add a little here.

So basically, the TWISTED lut is the easiest to use and gives most pleasing colour and tonality with only a few clicks. It works great on every clip I've tried it on and I'll probably use it for 99% of my work.

Nevertheless, this ADVANCED lut is actually amazing if you take the time investigate how it works. It can give results that are remarkably similar to film in terms of colour, saturation and contrast, but you have to work at it!

Question about using Arri Log C as your timeline display LUT w/ Resolve - when I go to export files that I've graded this way, the timeline display LUT isn't baked in to the exported image.

I'm not a Resolve expert but I think timeline display luts are only for monitoring and so aren't exported. So that would be normal behaviour.

Not bad. I use it with cr2hdr.app by simply throwing it into the ProRes4444 folder when exporting to ProRes. Cineon log x your ektar. Of course lacks the possiblity to change the contrast etc.
How do you build you 3D lut? It´s always nice to have the ready result but it´s even more interesting to follow how the lut is done.

Hope you get results that you like!

How do you build you 3D lut?

I'm learning all the time. This is what I did to build these luts

Find a photo of a colour chart taken on film:

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs27.postimg.org%2Fn9ymwtzer%2Fimage.jpg&hash=040424a3fd5be63a6a47b72308b3c2d0)

Crop, reduce noise, blur and extract squares.

Ektar:

Cinelog C:
(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs27.postimg.org%2F47f99woeb%2Fimage.png&hash=d94d614670986a592cbf7b5aabe63fce)

Use curves in Photoshop to match gamma (colour picker on the grey squares for each photo, write it down and manually type in the values for input and output)

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs27.postimg.org%2Frplnfu16r%2Fimage.jpg&hash=5469f6acc498ecfd740de1caf47923de)

Bring both images into Resolve and overlay one over the other. We want to match the ML with the Ektar

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs27.postimg.org%2Fukyqmp56r%2Fimage.jpg&hash=342e73cfee8f4e0d835746dbede00889)

Use https://generator.iwltbap.com/ to convert the Photoshop curve to a lut and add that as a first node

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs27.postimg.org%2Fkoxnn1zer%2Fimage.jpg&hash=33225f3cd91bf5a8a573c2a2bf7fb60e)

Use hue v hue to match hue, using the vectorscope angles as a reference

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs27.postimg.org%2Fl2yzmnjib%2Fimage.jpg&hash=90ed2ff3e254064876a9a8df1a565c9f)

Use hue v sat to match saturation, using the vectorscope lengths as a reference

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs27.postimg.org%2Fk1yqxj2ir%2Fimage.jpg&hash=34f94134c7e9ff939afa0e097ba04964)

So, for the first few versions of the Ektar lut posted, I didn't match the gamma... only the colours. This is because I had independently found a nice gamma that's easy to work with. For the twisted luts I actually created 3 luts - highs, midtones and shadows. Then I applied those to three HALD files, as per the IWLTBAP link above, and used "blend if" in Photoshop to merge the 3 luts together. The last lut I posted, ADVANCED, has a different curve and colour response in the highlights, midtones and shadows.

Thanks Danne, I'm just happy to be able to give something to the ML community.

IWLTBAP lut generator is great for creating luts from any application that can load and export a JPEG or PNG. Of course, in Resolve you can right click on a clip and export its corrections as a lut. I'm using a combination of both here.

PS: This technique also works pretty well for matching cameras. You don't even need to buy a chart - just do up some colour and greyscale squares on your monitor and shoot that.

Ah, that's definitely interesting and sure makes sense with why the recent TWISTED version feels so candy and I'm definitely going to use this one for batch processing together with Cinelog-C all within @Danne's latest cr2hdr.app (https://www.magiclantern.fm/forum/index.php?topic=15108.msg146822#msg146822cr2hdr.app) from here on out for the time being!

Re: ADVANCE version is rather tricky to work with (Thanks for making it this way) otherwise we could easily bore our way out from not utilizing our creativeness by relying on the others (LANDSCAPE, TWISTED) too often. This is a game changer and probably the most challenging LUT of all three. For good reasons, obviously!  8)

*edit*

I just noticed something noteworthy after taking a peek at http://www.kleptography.com/dl/5diii/raw/ (http://www.kleptography.com/dl/5diii/raw/) and if you scroll down to look at his photos and read the spec/settings used for each shot...

Especially the Exposure Compensation which was mostly if not all taken in -1/3 underexposed to accommodate for that certain gamma curve look, however, I am not sure if we should take this into practice when it comes to shooting in MLV RAW. Might be worth to experiment after all.  :P

ADVANCE version is rather tricky to work with

Absolutely! I went out this morning and took a lot of photos to test out the lut. It works well out of the box about 10% of the time  ;D Try this version 02 instead:

https://drive.google.com/file/d/0B1exEpCRAfgFaGpDOTh4VVQxSWs/view?usp=sharing

In the first version of ADVANCED I was trying to make it work a bit better by adding a curve before the lut to raise blacks and lower the whites a little. But I see now that it doesn't work too well as the blacks get murky. ADVANCED v02 is actually the pure lut itself without any of my fiddling. It's even more contrasty, but I think I'm beginning to see how to get good results fairly easily in the first exposure adjustment. Here's the order of operations:

1. Colour temperature & tint
2. First exposure adjustment
3. LUT
4. Second exposure adjustment
5. Saturation

So in step 2 here's how to get quick results for normally exposed footage:

Option A: Curves - bring down the whites until highlights sit at around 80 to 90 IRE. Now grab the middle of the curve, raise it and wiggle it around. Blacks should be OK but if they get lifted you can bring them down again later.

Option B: Classic exposure adjustment (lift-gamma-gain or similar) - lower the gain and raise the gamma. For example, in After Effect's Offset effect, exposure -0.75 and gamma 1.15 is a good starting point.

Let me know how this works out! I'm really intrigued by the ADVANCED lut as it just looks so goddamn like film!

I apologise for the wall of images, but it was quite quick for me to get this range of results using the above method:

There's something about the ADVANCED 02 that gives the a really nice filmic contrast... if you can get it to work right!

I guess my question is, for anyone who is using Arri Log C as a Cinelog C substitute in Resolve - how are people able to export with the grade intact?

Try these settings to get a close-ish match to Cinelog-C from ACR:
(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs23.postimg.org%2Fgdz1th5yz%2FUntitled-1.jpg&hash=d0c2c3635d469478a55691679e6c4609)

The colour won't be exactly the same (ACR just has nicer colour) but the gamma should match more or less.

EDIT: Or you can leave the output lut blank and add whatever lut you want as a node. This way you have control of the image after the lut.

I tried follow your tips (change exposure, and saturation, etc.), but my result wasn't good. What I do wrong or maybe it is too difficult for beginners?

First of all, make sure your project settings are exactly the same as what I posted above (except for output lut - just leave that blank as we'll add the lut in a node for each clip for more precise control, rather than setting it as an output lut)

So here's a DNG debayered into Log-C using the project settings posted above
(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs23.postimg.org%2Fnlv3vydez%2FUntitled-3_0007_Layer_2.jpg&hash=ed25637e022e137d88c12a6545e155cb)

Add the lut to a node
(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs23.postimg.org%2Fpey0k9yln%2FUntitled-3_0006_Layer_3.jpg&hash=42ab02681ed0c769f4d66ca87287a642)

This is the result

Not too bad in this case but maybe a bit too bright and contrasty. So let's try a curves node before the lut. I'm going to bring down the whites and raise the midtones
(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs23.postimg.org%2Fkiudskygb%2FUntitled-3_0004_Layer_5.jpg&hash=8656edd93c8727ca709d140fa64190ff)

Here's a similar approach using gamma and gain instead of curves
(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs23.postimg.org%2Ftrwk2p7cb%2FUntitled-3_0003_Layer_6.jpg&hash=c2129d086b9573676dddf791b03922e6)

OK. I'm happy with the tonality but want to cool it down a bit so I "unlock" the Camera Raw controls by setting Decode Using to Clip and White Balance to Custom
(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs23.postimg.org%2Fk7hzcxobv%2FUntitled-3_0002_Layer_7.jpg&hash=f6349fbb3685e718d1c6a949b74dd1a2)

Now I add a node after the lut to tweak the blacks
(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs23.postimg.org%2Fe7u89a3jf%2FUntitled-3_0001_Layer_8.jpg&hash=32f6c8970c41381c636ee12fb0a6d4b9)

And add a small amount of saturation
(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs23.postimg.org%2F6hng4517v%2FUntitled-3_0000_Layer_9.jpg&hash=c408d7024a409e4158c4ac4736e4d007)

Voila! And this is the same process using ACR Cinelog-C to After Effects

First of all, make sure your project settings are exactly the same as what I posted above (except for output lut - just leave that blank as we'll add the lut in a node for each clip for more precise control, rather than setting it as an output lut)

Thank you for your response, but I still have issue. I noticed that i can't choose Input and Output colorspace.

I think I see the problem! You're stuck on a Rec709 gamma for input out and output colour spaces but they both should be set to bypass. You should switch these settings and it should be ok:

Looks like both of you are getting the same results using my settings. I'm on version 12.2 - maybe that's the reason? If you guys are on 12.5 there might be something different going on with the colour management settings.

I'm no expert on this. Baldavenger or Andy600 would know the answer to this.

What happens if you make a new project from scratch using the settings I posted?

EDIT: does this post help?

Im using 12.5, and it seems like changing Timeline color space do not alter the gamma. The rendered file is more flat, but still far away from LogC gamma.
In the Resolve FX library there is an option to convert the image between color gamuts and gammas. Could you please do a tutorial using that? (i tried it, but i got different result compared to yours)

Edit: at first sight, Andy's tip is working, testing...

If you expose correctly you should not push to exposure slider 2,5 stops. With ETTR shooting 0 - +0,66 is enough
Title: Re: Free Ektar 100 LUT for Magic Lantern footage
Post by: hyalinejim on April 26, 2017, 11:55:47 PM
@deadcode
The 2.5 exposure boost is to get the image to match the output of Cinelog-C from Adobe Camera Raw, which is what the luts are designed for, as ML DNGs come in quite a bit underexposed in Resolve. This is certainly necessary in 12.2 as you can see above with Resolve and AE workflows, but maybe it's different in 12.5 with the recommended settings.

@Tom_LS
That looks right - I think you're good to go!

Hey, that's looking damn good! @Tom_LS

It's not always easy to get a good look out of ADVANCED 02, but it's very versatile. Have you tried to use TWISTED? It's a little bit less powerful, but a lot more straightforward.

I was thinking about what DeafEyeJedi wrote earlier and if TWISTED = CANDY, then I think ADVANCED = WHISKEY!

Thnx,
I have another question. I use crop mode 3x3 binning for slow motion. I'am using AETTR when I shoot. It is ok in good light condition (daylight), but in low light it's changes my canon ISO value to max. It's strange for me, because when I'am shooting h.264 I need, for example ISO3200 and ISO12800 for RAW in the same light condition. Is it normal?

Would you please create a more universal version about the Ektar LUT?
It took me an hour to match my 5D Mark II Raw to my A6300 SLOG2. It would be awesome if you can make a "REC709" version. "Twisted" gives different result with SLOG2
Here is the result: (https://www.magiclantern.fm/forum/proxy.php?request=http%3A%2F%2Fwww.kepfeltoltes.eu%2Fimages%2Fhdd1%2F2017%2F04%2F28%2F108Ektar.jpg&hash=03d9e1ad693edeff7bb0bb39a189e02a)

Well, I don't have any Sony cameras so can't help you out there. The lut is designed for ML Cinelog footage. However, if you'd like to use it with your Sony I would suggest first making a lut to match SLog2 to Cinelog in terms of tonality and colour. Then apply the Ektar lut. I did this with my XC10 and now I can match that easily to my 5D3.

Here's how I did it:

1. Load up a white image on your monitor
2. Colour balance each camera against the white image and slightly defocus
3. Find the point at which each camera clips highlights 100%
4. Take a series of videos, lowering by 1/3 stop each time until you get down to 12 stops (36 videos)
5. Denoise and blur each clip
6. Separate them out into individual squares, arranged horizontally. Now you have a map of the tonality of each
7. Use curves to match one to the other (split-screen one on top of the other and match the curve on the waveform)

That's the first step. Once tonality is matched, it's time to match the colours. See my post above on how to do that. All of this takes time, of course, but it's a great skill to develop as you will be able to match cameras fairly closely. Here's how my Ektar luts look on the XC10:


When I shoot it side by side with my 5D I can slap a lut on the XC10 and it matches pretty closely. Looks like you got a close match from your screengrab - maybe you can use that correction in future?

Thanks again to @hyalinejim for forcing us to dig through puddle of mud in order to fine-tune Ektar ADVANCE_02 into decent looking images. It's so Filmic that it perplexes me (in a good way) about the fact that this is possible even during a time where Film is literally facing some sort of an extinction, unfortunately.

Decided to test this one out by ETTR on Willoughby during an early morning w sunlight peaking through from a nearby window w 5D3 shot on Helios 44-2 wide open in 45p 1920x1080p 12-bit lossless @ ISO 1600 and here's what it looks like going from Adobe Standard to Cinelog-C to ADVANCE_02 (as is) to ADVANCE_02 + Curves to ADVANCE_02 + Curves & Saturations just for those who are curious:

That's a nice looking cat!

Ektar ADVANCED 02 gives terrible results at first, but then gives very filmic results once you fine tune how the signal enters and exits the lut.

Check out these saturation control luts. One of them rolls off saturation in the highlights and shadows. The other pulls back on rampant reds or anything that's going to blow out (particularly useful for the TWISTED lut). There are two versions of each - medium and strong - and they should be the final luts in the chain.

https://drive.google.com/open?id=0B1exEpCRAfgFWWFoNzBQSEd1MVU

By the way, I've been busy creating lots of looks for the GH5. I'm still in the process of deciding which are working well and which are a bit crap. When I do, I'll convert the best of them for Magic Lantern and post them here. Here's a preview of what's coming down the line:

The advanced lut is a bit wacky. You need to play with the tonality before (and after) the lut using controls that will alter the whites, midtones and black levels... such as levels, curves or lift-gamma-gain.

It gives unexpected results - sometimes it's a nice surprise and sometimes... not as nice. I promised earlier to make more luts and I still plan to do that. I'm shooting a roll of Fuji 400H at the moment and have shot a Wolf Faust IT8.7 target with it at various exposures. I'll do up a lut based on that in the next month or so.

Sit tight, guys. I'm gonna make a really great Ektar lut. I've been shooting lots of test charts, with lots of rolls of film, and testing lots of different ways of matching contrast and colour. Maybe in like four or five weeks I'm going to post a LUT that will match, fairly accurately, Ektar 100 as processed and scanned by one of Europe's top film labs.

Here's a taster of what I've been up to. In this case it's Portra 400 developed and scanned by my local camera shop,

Could you also give some hints about how you emulate film? ... such as which hues shift in which direction... in what way is saturation affected... curves, or any other relations between factors. Possibly??

Those stills look really good!
Title: Re: Free Ektar 100 LUT for Magic Lantern footage
Post by: hyalinejim on October 02, 2017, 11:59:53 PM
It's not particularly straightforward! Each film stock has different characteristics in how it renders certain hues - Portra 400 may have warm greens and tan skintones, whereas Fuji 400H will have cool, minty greens and pinkish skin, for example. In addition, contrast and saturation increase as exposure increases with film, and there are various colour casts in the shadows and highlights at different exposure levels.

We are used to exposing plus or minus one with our digital cameras, and seeing a noticeable increase or decrease in brightness. But when negative film is scanned by a lab, the scanner usually automatically compensates for these exposure differences. You end up with bracketing tests where the brightness doesn't seem to change much, but the colour and contrast does:

https://carmencitafilmlab.com/how-exposure-affects-film/

My methodology is first to match the general contrast and colour shift using curves, and then to fine tune exact hue and saturation reproduction for various colours using a LUT. I've dabbled with trying to introduce the film emulation as a DCP profile, but the results aren't very good. I'm getting more consistent and accurate results by debayering (to Cinelog in the case of Canon DSLR RAW but I also get great results with GH5 VLog 10bit) and then adding curves and a LUT.

Sit tight, guys... ...This is all still a work in progress. When I'm happy I'll come back and give you guys Ektar 100... ULTIMATE!!!!

Buckled up and ready for the ULTIMATE ride back to the future. Please take your time on this one, sir!  ;)

It's not particularly straightforward! Each film stock has different characteristics in how it renders certain hues - Portra 400 may have warm greens and tan skintones, whereas Fuji 400H will have cool, minty greens and pinkish skin, for example. In addition, contrast and saturation increase as exposure increases with film, and there are various colour casts in the shadows and highlights at different exposure levels.

But when negative film is scanned by a lab, the scanner usually automatically compensates for these exposure differences.

Definitely spot on. This is probably why it's extremely useful to shoot in ETTR or slightly more depending on subject in scene.

My methodology is first to match the general contrast and colour shift using curves, and then to fine tune exact hue and saturation reproduction for various colours using a LUT.

I can also confirm this consistently not only with Cinelog DCP for Canon DSLR RAW and Vlog 10-bit for GH5 as well as with Cine-D (borrowed this camera few times from a coworker whom refused to split half $ on getting the Vlog update w me) and indeed it is quite a little workhorse while able to match them together nicely with your amazing piece of work that you continue to share with us @hyalinejim!

Very exciting times ahead for me and for fans of this lut: today I got back scans of the first roll of Ektar that I've shot. I took a series of chart shots at different exposures with which to do the matching, and I also had shot some A/B comparisons with Ektar 100 loaded into my OM1 (nice little camera!) and regular old CR2s on our friend the 5D. I spent a few hours this evening working on matching them. Some shots match better than others, that's for sure, as there are a lot of variables at play when shooting film. But this is one situation where the lut makes the two cameras quite close. The base for this lut was the new DCP profile that Danne and I worked on: ML-Log

https://www.magiclantern.fm/forum/index.php?topic=20710

OK, here's the 5D shot with ML-Log profile applied in Adobe Camera RAW:

Now, here's the Ektar 100 shot. Nice, isn't it?

And finally... here's ML-Log with the Ektar matching lut applied, with some exposure and white balance tweaks. Also nice!

And one more for good luck! The film scan is in the middle:

I'm gonna work on this some more over the next week or so and when I'm fully happy with the results I'll release it.

Love this work. And the resemblance is very good.
By the way. I love th OM system. Owned most of the cameras back when shooting film. OM4ti with spot metering was the hardest to let go. I kept a few of the lenses. 40mm f2, 21mm f3.5, 24mm f2. They all have their own personality. Use my 40mm on the 100D all the time.

Yeah, nice job @hyalinejim. It's really close now to the original Ektar. I didn't like the fist version (although I was using on Rawtherapee), but these last ones seems really good, thanks.
I own a OM1 too, it's a good camera.

...[fanfare of trumpets]

I'm ready for you guys and girls to check out this set of Ektar 100 Luts:

DOWNLOAD EKTAR 100 ULTIMATE SET:
https://bitbucket.org/hyalinejim/ml-log/downloads/MLLog1.3%20to%20Ekt100.zip

These are built for ML-Log v1.3, which is a work in progress.

DOWNLOAD ML-Log v1.3:
https://bitbucket.org/hyalinejim/ml-log/downloads/5D3%20ML-Log%20v1.3%20Simple.dcp

Read more about ML-Log:
https://www.magiclantern.fm/forum/index.php?topic=20710

So you can think of these luts as also being a work in progress. They are designed to be applied in the following workflow:

1. Import DNGs into Adobe After Effects
2. When Adobe Camera Raw opens, choose ML-Log v1.3 for the Camera Profile
3. In After Effects add the Apply Color Lut effect, or export to an intermediate codec for grading elsewhere

What's the deal with these luts?
These luts fairly accurately emulate Ektar 100 film, as scanned by a specific lab and at various exposures. With negative film as exposure increases so does colour and contrast. And there are different colour casts in the shadows, midtones and highlights at different exposure levels. The five luts here emulate these changes in colour and contrast from two stops underexposed to two stops overexposed. I've labelled them A to E and added plus or minus marks to indicate the exposure level. I've also carefully adjusted the tonality and white balance of each lut so that middle grey falls at the same point for each one. Applying the minus two lut won't make your footage look underexposed, nor will the plus two make it look overexposed. However, you'll notice that the minus two has very milky blacks, a generally cool tone and muted colours. The plus two is much more contrasty with overall warmer tones and hyper saturation, especially in the reds. It may be too much for skintones, as is often the case with real Ektar 100 film. The middle exposure lut has the most neutral colour cast.

How to approach the luts in post


There are two things you're going to want to be able to do to work with these:
1. Manipulate white balance somehow (both on the orange-blue axis and red-magenta axis). Lumetri is good for this. You can also try a three way colour corrector in the midtones
2. Manipulate black, midtone and white levels. I like to use curves, but levels or lift-gamma-gain controls are also good

Both of these should be done before the lut. So don't feel that you're stuck with a particular colour cast or contrast level with a given lut. If you like the colour of "D +" (one stop over) but find it too contrasty, just lift the black point and lower the white point before the lut to lower overall contrast. Use the midtones control to adjust overall exposure.

I 'll illustrate the differences between the five of them in more detail later. For now, here are some random CR2s I grabbed from Imaging Resource and applied the luts to. These images were exposed well and the results here are straight out of the box:

MLLog1.3 to Ekt100 A - -

Post by: bpv5P on October 21, 2017, 08:57:42 PM
Great hyalinejim, I've yet to try these ones with ml-log 1.3.
I think it would be a good idea to keep the opening post updated with the last version, so people that fall here from google in future don't need to read all the thread just to get the luts...
Title: Re: Free Ektar 100 LUT for Magic Lantern footage
Post by: hyalinejim on October 21, 2017, 10:10:54 PM
Yes, I'll do that at some stage when I feel that I've got it nailed. There are a few variables that I still need to figure out, and I need people's feedback here.

I'm going to upload an alternative set of the five luts. In this second set, the exposure does change with each lut. So the underexposed luts will give you a darker image than the overexposed ones. I'm curious as to which of the two sets people prefer, and why. I think I might prefer the second set as I like seeing the difference in exposure:

https://bitbucket.org/hyalinejim/ml-log/downloads/MLLog1.3%20to%20Ekt100%20v1.1.zip

Another question is how to manage the colour casts. In both sets, I've been calibrating the white balance to 90% white for each exposure level. This more or less standardises the colour across all five luts. Then I go back and make "C" (the properly exposed shot) neutral across most of the midtones. When I apply this correction to the other four it re-introduces some of the interesting colour casts, which I think is desirable. The problem is that each film scan (on a Noritsu or Frontier film scanner) can vary a little from shot to shot. It's not like opening a series of shots in ACR where, if they were shot with the same settings, there will be absolute consistency. So in designing these luts I need to figure out when, where and how to compensate for the variances inherent to film scans. The luts made directly from the scans are a little bit inconsistent in the progression of colour and contrast changes that you would expect.

In pictures, here's the difference between the two sets:

v1.0 (exposure stays more or less constant)
(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs1.postimg.org%2F2iop45jphb%2Fv1.0.jpg&hash=7c9d792a0c399ce135cf37fec079b3b4)

v1.1 (exposure actually changes)
(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fs1.postimg.org%2F7jgrvprmkv%2Fv1.2.jpg&hash=3c3d52e9865d479910e45605b1e6443c)

One final thing to point out (and this is something I may need to work on) the underexposed versions of the luts give odd shadow colour and tonality if you pull the blacks down before the lut. The reason for this is that the RGB curves diverge very strongly in the shadows for the underexposed luts. If you want darker shadows with these versions it's better to pull them down after the lut.

On the other hand, all five luts loooove overexposure. So don't be afraid to lift the midtones pre-lut for a very contemporary effect. There should be good highlight roll off too!

How are you doing the scan hyalinejim? I did some research some years ago (while working with analog photography), the best process was:
- Very a photo in a color chart
- Get VueScan
- Adjust WB based on 18% grey:
http://www.hamrick.com/vuescan/html/vuesc12.htm#topic6
- Put the VueScan on  highest settings (resolution and dpi)
- Scan on normal exposure using DNG:
http://www.hamrick.com/vuescan/html/vuesc15.htm#topic9
- For better quality, you can use "multi-scanning" (although I personally would do it manually, using different scan exposures and then blend with HDRMerge):
http://www.hamrick.com/vuescan/html/vuesc23.htm#topic17
https://jcelaya.github.io/hdrmerge/
- The use of anti-newton glass and wet mounting can facilitate the scanner focus:
http://www.betterscanning.com/scanning/usinginsert35.html
http://www.betterscanning.com/scanning/msfluid.html

That way you get a pretty raw scan.  There's also other variables that can change the film color, such as the development process (C-41?), push-pull and if it's expired or not...

Post by: hyalinejim on October 22, 2017, 01:30:00 AM
Yes, I considered different scan options but decided to stick with a lab scanner as they impart a look of their own. The chart shots were processed and scanned on a Noritsu by Carmencita Film Lab. They have a good reputation and some of the work on their website is amazing.

If these luts do what they're supposed to, it should be possible to get close(r) to these kinds of looks:

Try this set of LUTs for a similar look in Resolve:

I used these settings, so it's expecting this kind of input:

Then you'll need to use curves or lift, gamma, gain to bring the log signal into range:

In theory, yes. I would just need a C200 first! But there's a fair bit of work involved in making these luts. That's something that I might start doing commercially for cameras other than ML over the coming months.

Edit: even tho I live this LUT especially the colors I found the standard lut to be a smidge punchy as Ektar usually is. So I put the key output gain to 0.700 and set the color management to Davinci YRGB Color managed and used arri Log c for Everything. Over all I am VERY impressed with this LUT Bravo!!!!!

Lattice is great but it's not open source and it's Mac only.

You should check out https://cameramanben.github.io/LUTCalc/ (https://cameramanben.github.io/LUTCalc/). The online version is free but the Chrome and OSX versions are only a couple of dollars. You'll need to understand what you're doing to get the best from it but it has a comprehensive feature set and the source code is available if you wanted to go deeper.

Can you explain this? I'm having trouble grasping the workflow needed to use this lut in MLVapp.

These are the steps I took
-drag mlv file into mlv app
-color balance white (Selected the white van)
-color balance face option (selected a persons face)
-apply the alexa c-log (with camera matrix on)
-enable ektar lut
-adjust color temperature

What am I doing incorrectly?

The LUT is made for ML log, not Log-c or any other Log formats. The lut expects ML-Log input.

Okay. ML-Log is not supported by MLVApp, so you'll have to do it "post-MLVApp". Btw: how is ML-Log defined? Is there e.g. a LinearToMlLog LUT? Maybe we could add it as profile in MLVApp...

Main intention to be used in acr as dcp profiles. hyalinejim got the tools, color charts etc so maybe he could build the log lut. As it says in the first post it´s very similar to cineon signal. If choosing cineon in Mlv app then add the ML_Log to film curve clean v01.cube it pretty much looks like rec709.

I'm just using PS to apply the lut, I don't really use PS at all (unless I need to manipulate an image in a physical way, like remove some object). I use rawtherapee because it's the most advanced raw processor I know, and I've tried many.
Rawtherapee has the support to apply lut, but just Hald CLUT, not 3dLut. I need yet to convert the luts I use to Hald CLUT to use it directly without photoshop.
I'm actually planning to do all the work with rawtherapee on a MLV project I have, and then just glue everything with kdenlive, so I can keep it all open source...
