@masc Finally tried the HSL adjustments: they're amazing!!! There is the ability to fine tune it, unlike rawtherapee's HSL adjustments where moving the mouse one pixel changes the hue by 180 degrees already. What we have in MLV App is a usable interface with controls that are not horrible, very rare in open source image editing. Thanks for all the great features you have added recently.

@timbytheriver
Exposure slider is linear and simulates more intense light. The lightness slider is more of a curve and brings dark tones up more than light ones. Use them however you think gives a nicer looking result... and never underexpose :D

Absolutely! +1.5 is the way to go. Thanks for the info about the sliders – I didn't know that. :)

Glad you like it, as it is initially your project. ;)

@Ilia3101 @masc

Would it be possible to add a False Colour overlay option to MLV App – or is this voodoo?  :o

Thanks!

What exactly do you mean with that?

It maps various exposures visually – like an overlay in hi-end monitors! :)

There is way you can do it in Photoshop detailed by user 'crifida' in the comment section of this article: https://wanderingdp.com/cinematography/cinematography-school-lighting-ratios-101/

False colour is literally some if statements for brightness of a pixel. But what's the use?

For on-set monitoring it shows the relationship between where certain values are 'placed'. Very useful for 'seeing' lighting ratios. E.g. Key to Fill, where skin tone values are. The various false colour values can be adjusted to suit the cinematographer. In a post production workflow you can still use the false colour to assess the relative brightness levels of subjects.

This explains it better than me:  https://wanderingdp.com/cinematography/cinematography-school-lighting-ratios-101/

@timbytheriver:
do you know this page?
https://cameramanben.github.io/LUTCalc/LUTCalc/index.html

Here you can create a false color LUT as you like to have it. Generate it, load it into MLVApp's LUT slot and see what happens. Should do the trick! ;)

@masc Many Thanks! That looks a very clever way of doing it! :)

What camera and gamma settings did you use in the first box?

I used general, rec709, sRGB. No idea if that is correct, but the LUT is the last step in processing, so camera type doesn't matter. The viewer should be sRGB and we export to rec709. That's why I've chosen this setup. But again: that might be wrong.

Great, thanks! I will do some experiments.

Is this looking correct?

Hm... completely different from what I did yesterday, but maybe more correct. I now tried this, and it looks plausible so far. Maybe Ilia can look at this!

Can't seem to get any clipped areas to show Yellow or Red – even if I push them off the scale.

Are you saying I should be in sRGB instead of Tonemapped for the working space in MLV App?

No, what you set before doesn't matter. The viewer itself is always sRGB. So if you push it you should see something. I get it orange here in highlights.

Thanks masc. Highlight false colour seems to be working when I use your LUT! Maybe I did something wrong…  :o

Tone mapped is sRGB, it just doesn't clip to 255 easily. You could use the sRGB profile if you want more clipping 🤕

And for the lut generator, I think sRGB is what you should use as the viewer is assumed to be sRGB.

Thanks @Ilia3101 :)

@masc Could you post a complete screenshot of your LUT calc settings please? Whenever I generate a LUT the highlight clippings (orange and red) still don't show! Only your LUT works…

Many thanks!

Is there a way to play the cinemaDNG files/folders? I have been using the original mlrawviewer 1.4.3 to play the cinemaDNG files (folders) from the blackmagic pocket camera without any issue. I just drag-and-drop the folder over the mlrawviewer, and it will start to play. I would love to be able to do the same with this app.

thanks

Nope, was asked multiple times and it is very complex to realize. Not worth it, there're alternatives.

Hi,
I just used DualPixel for the first time
Unfortunately I did not get the result I wanted…
I use a mk III and compared two exposures - one with and one without Dual Iso
Dual Iso was set to +2 EV
In MLV app 1.5 I clicked on force on The Dual Iso file and then set it to on
Then I processed the two files (that looked identical in MLV…) to two H264 movies, opened them in Photoshop and compared
BUT I cannot see any difference in the shadows!!!
What did I do wrong?

Maybe share some trimmed samples of your original MLV shot in Dual-ISO for us to see and test with @olofen?
