Colour Appearance & Lighting has trouble "remembering" settings

[epadepa]

Short description UI temp settings inColour Appearance & Lighting > Automatic Symmetric > Illuminant: Free is "forgotten" when switching back and forth between images. The module has also reverted to Classic Mode when switching between images, can't reliably reproduce this however.

Steps to reproduce

1. Set mode: Automatic Symmetric in Colour Apperance & Lighting
2. Illuminant: Free
3. Temperature: Noticeably high or low say 2000
4. Switch to other image in filmstrip
5. Switch back to image with changed Temperature
6. Note that UI is now showing a temp of 5003 whilst the image is still blue

Expected behavior The UI should show a Temp of 2000 as set in step 3 above.

I will have a look, but probably not today... To better understand, CIecam is complex in colorimetry and code, is it possible to have an example with raw and pp3...

Thank you

It seems to be a pure UI issue. The slider and the temp number doesn't show the value acting on the file after switching to another image. It's not related to what temp you input, what file you use etc. At least not in my testing.

If you can't reproduce from the description I can investigate further and upload samples raw+pp3.

@epadepa Ok , I will have a look :)

@epadepa

I cannot reconstitute... I try, I try, but the temperature stays the same.

What exactly do you mean by:

4. Switch to other image in filmstrip
5. Switch back to image with changed Temperature

If on the other hand, you mean that you go from "Advanced" mode to "Standard" and after in "Advanced" mode... but that doesn't seem to be the case, yes in this case it changes, but it's "normal"...

:)

Thank you
