I've gotten myself totally turned around when it comes to setting up the new color management features of XSI 7. Most likely because I took a 6.5 scene and opened it in 7 and now with the built in correction, many of my shader settings seem off. Anybody out there know how to really get the right settings for a Linear workflow?
Under Preferences > Rendering > Images I set "Color Profile" to "Automatic" and left the "Gamma" at the "2.2". Most of what I do is use procedural shaders so this won't matter too much.
Under Preferences > Display > Color Management I turned all the "Apply to..." to on. "Profile Source" is set to "From Gamma Values" and the "Gamma Values" are all set to "2.2"
I removed the "mia_Simple_Tone_Mapping" Lens Shader from my camera because I assumed the new Display Preferences would now handle the Render Preview adjustment for me.
I do a preview render from the UI and...my scene looks washed out.
My shader balls look washed out...but only if you toggle the "Apply to..." preference off and on while the Material Manager window is open. Bug?
All the UI Widgets like RGB or HSV grads appear more linear than sRGB. Not sure if that's good or bad.
Now is this because I've set my Display Gamma values to "2.2" instead of "1.0" (because that makes the preview render look more predictable) or because I set my shaders and lights up in 6.5 while operating under some silly non-Linear workflow?
Or is my logic all off? I tell XSI to display correct to 2.2 because I'm looking at it on a 2.2 display device. I set all my lights and shaders up while rendering with the correction on. Shaders and lights applied from an earlier XSI version are going to look washed out. I render to openEXR which is Linear and then I tell my compositor that my files are Linear and/or I apply a .454 Gamma corrector when I output my final frames from the compositor if my target is NTSC.
Following that logic would mean that I need to fix my lights and shaders for the real color space...or take the lazy way out and just apply a correction for the correction.
