Feature Requests / [ALREADY DONE] Focus Stacking # of Pictures 100+
« on: July 26, 2014, 12:21:36 AM »
I looked through focus.c for a value for this but couldn't find one to edit.


For this I used the new Full Res Silent Pics along with Focus Ramping (not Intervalometer). With 1 step focus adjustments and a 10 second delay, this was as long as a timelapse you can create in this mode. 101 frames. Is it possible to allow the counter to go up to 1000, or 999? Or a less practical way would be to enter a numeric value using the input modules, because it would depend on the user loading the module.

Can't go over 30fps on the 50D.

A few tests on the 50D show different ms. Haven't gone through the whole range, but matched ISO100 and f/1.4

Shooting at 5s gave 5607ms
Shooting at 1/10s    310-312ms (this too seems to be the sweet spot for no darkness at top of frame, with least amount of motion)

That's interesting dmilligan, I have a build I made myself from the 50D fullrespics branch and everything worked fine with correct centering with the silent.mo that I built.  When I switched to your new module (while keeping the rest of my card untouched) the mlv saving function worked great, but I have black bars.

Went back and tested with your module saving in plain dng and the framing/centering are correct.  Switch to mlv and I get black borders.  Have two files if you want a look.

Thanks for getting those stubs ayshih. Just built with fullres silent pics and it is working great. Sadly not a cloud in the sky for a timelapse tonight.

Loving the new package Andy!  Getting some nice results with a quick workflow now.

One question I have, what is everyone using or what is the preferred method of noise reduction for this workflow?  I'm used to using Neat Video plugin for FCP, but with these nice new PFE LUTs applied, I doubt the ISO profiles in Neat would work out (haven't tested yet, not home).  I imagine this would only be for problem footage at 800ISO+ with the PFE grain distracting from much of the noise at lower ISO footage.


I'm thinking either;
export from Resolve before PFE and use Neat Video then roundtrip back to Resolve, apply a PFE -> Profit
or
run DNG files through ACR first to get rid of noise, regular edits in Resolve with a boost to midtone detail or --blur Y channel to sharpen.

Thanks

The expected results are based on your last recording speed (I think). Don't pay too much attention to them.

For 1920 recording, use the button on the top right of your camera to go into 5x crop in LiveView. Once you are in that video mode, 1920 resolutions are available to record at. With my 1000x and 1066x cards, I can record continuous 2.35.1 ratio at 1920.

One of the main selling points of .mlv over .raw is sound recording. The 50D has no sound input. However the metadata stored with each frame in .mlv is a very nice improvement over .raw

Hmm, I haven't been able to reproduce this with further testing...

Shots during "Don't Click Me" test worked fine for me on the 50D.  After trying to shoot .mlv with extra memory worked until card was full (forgot to clear it first).  Haven't seen error 80 yet, but trying on a clean 1000x card now to see how many frames I can get in crop mode.

Thanks for getting this going on the 50D, I like Andy was having a hard time looking for the stubs until it was cleared up a few posts above.

Got the 50D with everything but the composite cables.  I'll try to track them down later today (I'm sure they are at the bottom of a bag somewhere).

Is anyone using DaVinci Resolve 11?

After converting in ACR (tried both bridge & photoshop) to cinelog (and checking and updating metadata to confirm it saved in cinelog) when I import into Resolve 11, it does not show in log colourspace.  Shows up as shot or prior to conversion in ACR.  Tried on multiple clips & checked my monitor LUTs to make sure it was not that. 

Anyone else with this issue?

General Help Q&A / Re: Dual ISO help needed
« on: June 30, 2014, 02:22:44 AM »


Found a throwaway shot to demonstrate a quick edit. (Not interesting & I'm in the reflection)

In most cases I pull my highlights 90% to 100% down.  Shadows over 60. Boost the whites depending on the scene, and bump a bit to the blacks.

14
I think everything I use is cross platform now.

MLRawViewer for viewing .mlv files and then conversion to .dng within the app
The cr2hdr Lightroom Plugin for dualISO .cr2 to .dng conversion
ExifTool for black point reset (if set incorrectly in mlvrec module)
Resolve Lite
Photoshop & Lightroom CC for Adobe Camera RAW
LRTimelapse (timelapses)
StarStaX (dark frame subtraction)

Danne, like that second one with the centered sun and bird, but the architect in me is freaking out about those slanted buildings.  :P



Blew out the background highlights for impact on this shot, but I love the contrast I could bring back in the tree to compositionally bring your eyes back to the flower girl.

Rokinon 85mm
Canon 50D
Dual ISO 100/800

Favourite part is it was an unstaged/candid photo.  I was the second shooter and the main photographer had the wedding party posed over to camera left.

Haha ManU as well, but we can all root for the world cup.

Great piece and great Father's Day gift.  Love the closing shot and how the camera is bobbing with the wake (on a dock I assume).  Hope dad was happy!

I'm not the OP, but most DIY star tracking is done in the 'hinge' or 'barndoor' style.



Spinning the drive bolt raises/lowers the lens angle. With a bit of math you can time it so 1/2 turn = 1 sec (or whatever you prefer).

Were you in movie mode LiveView, or photo mode LiveView? It matters here.

Movie mode.  Get mixed results with LV on and Dummy Bracket.  Here is another one.  This one seemed to process, but the overlays are strange if I don't do halfshutter.

One thing I noticed while in LV was that I had to hold the half shutter till a box popped up top left of screen saying raw_diag.  Dummy Bracket didn't work for the 50D in LV.  Uploading a quick video (got a terrible curve, not on a tripod, no audio, just showing how to make it work) to show that it works in LV, just have to not use Dummy Bracket.

Are there any conflicts with the plot module? I didn't use it yet, but this refactoring is on my todo list.

No it seemed to work fine once I got the settings correct.  Before I had image review set to hold in the Canon menu I was getting the data, but I was also getting separate .ppm files in different folders under RAW_DIAG folder (IMG_0001, IMG_0002, etc).  Shown below.

@dsManning: can you retry the LiveView tests at ISO 400 and above? They have obvious outliers.

Fixed.  Same link as above.

Do I have to use a tripod? Found it - yes.

How long should it take to sample data? Mine's already working a couple of minutes - maybe it halted?
(600D)

Well, tried it for a couple of times. One time it always said "RAW Error", second time it halted again.

Make sure image review from the Canon menu is set to hold.  I had some issues with the different image layers (plot.mo grid, graphed data, curve line) all ended up in different .ppm files.  Seemed like it didn't have the time to process when it jumped back to liveview.  MAY be your trouble.

23
Would it be safe to use Dual ISO mode for a timelapses? taking maybe 300-500 shots at a time? Will this affect my sensors at all?

Daniel

No bad sensor exposure, same shutter count as a regular timelapse.  So this improves on HDR timelapses in the shutter count area, because instead of 2+ (usually 3 or more) per frame for an HDR, you get increased DR with one shot.  Just a heads up, as with HDR timelapse, your post processing time increases dramatically.

Hardware and Accessories / Re: Best Card for 50D RAW video
« on: May 27, 2014, 12:59:18 AM »
I get continuous HD crop 1920x818 which is a 2.35:1 ratio and looks great.

That is on both a Komputerbay 1000x 32GB card and a Toshiba 1066x 16GB card.

And I also get continuous 2.35:1 no crop on a Lexar 800x 16GB card.

Not sure what Jackeaatley has for some settings, but I'm even running with a few overlays on (focus peaking, vectorscope, histogram, etc) and I'm still not getting skipped frames on these cards.  Quite often writing up to 83 mb/s to the Toshiba and usually around 81 mb/s for the Komputerbay.  The 800x Lexar hangs more around 45-49 mb/s.

Hey guys, so I'm trying to make the jump to MLV to save myself having to adjust WB on each clip like in RAW, but I found that the "fix black level" option does nothing but create pink DNGs that even ACR has trouble reading properly. It seems like a dangerous design flaw to have that option automatically be enabled in mlv_rec. Can we make it harder to reach or simply remove it? I'm hesitant to use MLV now because I'm scared I'll accidentally turn it on or maybe after a bad reboot the camera will turn it on, and unlike some bad settings that can be easily dealt with, gross pink DNGs even in ACR doesn't seem like an easy fix. Thanks.

Don't worry. You can always fix it after, even if it does happen.
