Happy New Year!

Welcome to the forums, Han!

Maybe a "Reset Settings" would help?

Mine was acting up during Answer Time, but when I set the Gamma in the Rendering tab (Tools/Options/Rendering/Gamma) to "Custom" and "1" it started behaving itself...not sure why, I'm assuming it needed to be set to something now.

Here's what I get: Current_gamma_test.mp4

Merry Christmas!

I did some more digging and found info on Desired Gamma here (a page from Yves' website using the Wayback Machine). The paragraphs that apply are these: This would mean that the "Current Gamma" should be set to the gamma of your monitor (which should be 2.2 for everyone). Then, the "Desired Gamma" is set to the gamma correction planned...which, if rendering to a 1.0 gamma OpenEXR, needs to be 1/2.2 according to this illustration (found on this page): Reading Yves' description, I would assume this correction for a 1.0 gamma would be applied when "Desired Gamma" is set to 1.0, but that doesn't work for me...I get a white screen. It does appear to work if I set the "Desired Gamma" to 3.4. I've been using 3.3, but if it's supposed to work at 1.0 there would be a difference of 1.2 and that would be 3.4 (going in the opposite direction). So, I'm thinking that "Desired Gamma" may be working, but in the opposite direction as intended? Well, as long as it works.

The subject of Desired Gamma came up and I was unable to get my software to cooperate at the time, so, I made an attempt at a video explanation of the little I know that I am posting here along with the Projects used and renders. One thing I still don't think I got across in the video is that if you are working with 2.2 gamma images, the gamma correction can get re-applied automatically with each iteration causing the image or portion of image (and colors) to lighten. Anyway, here is the video and Project files. Hopefully, it is helpful. Desired_gamma_testing.mp4 Desired_Gamma_testing.zip

Thanks for everything you do, Jason! Sorry about your test and holidays. Time crunches are not fun.

I'll bump this in case it was missed.

This might work...although I made the transition too fast and sloppy. Test_12_03_2018.mp4 GradTest02.prj

Thanks, Jason!

Thanks, Jason!

Very cool! Thanks, Jason!
