Weird... I have noticed that sometimes, the 'sRGB' option for image
profiles doesn't actually work, and I have to set it to a custom gamma
and use 2.2 for it to look correct. But I have to say that all my prefs
for color mgt are off, and textures and colors look right. Of course I
also render out to linear space...

Tim, when I set all my Softimage Color Management Prefs to "off" the
colors don't look correct in the region. I am interpreting all the
input textures correctly as either sRGB or Linear as needed. I do not
have Automatically Correct Color Inputs (Redshift Settings) or Apply
Gamma Correction (Pass) enabled. It looks correct when I have all the
boxes ticked in the Softimage Color Management prefs.

To echo Ognjen here... We have all our Soft Color Management Prefs
unchecked, and we let Redshift handle everything. If you're
rendering to a color space like sRGB, then in the 'Output' tab in
the RS settings, under the Gamma section, set the File Output to
either 'Use Display Gamma' or 'Use Custom Gamma' set to 2.2. If
you're still seeing textures washed out, then their Color Profile
may be defaulting to Linear, which would cause the wash-out (since
you're rendering to sRGB 2.2).
Back on the Output settings tab in RS, you might also want to
enable 'Automatically Correct Color Inputs', depending on your
workflow.
Now, I almost always add a color correction node to all my color
tetxures in my shader trees, but I leave the values at their
defaults. This is just to give me controls later at the shot
level. I certainly don't drop the gamma to 0.45 on all the color
correct nodes. That's simply not necessary if RS is handling it
anyway, and XSI's color management stuff is off.

Thanks Ognjen. I did what you suggested but I'm still getting a
slightly washed out render that's a bit brighter. Must be
something else I'm missing?

Actually i dont think you should be color correcting your
shader nodes, that doesnt sound like a very smart thing to
do. All the native color managment settings in the softimage
settings should be off by default, and then you leave
redshift to correct everything for you, all you have to do is
to make sure that your displacement images are set to linear
in the image node, and color textures are set to srgb, and
that you have "Automatically correct color inputs" switched
on in the redshift settings to correct all your shader color
parameters. Theres no need for anything else then that. In
redshift your display gamma will be set to 2.2 and output
will be linear for exr by default.

Great thanks...was hoping it was just a few settings and
not tweaking each shader...but it is what it is. Is there
another way via just exposure settings in Photoshop and
render settings in Soft?

Straight to the pie:
1. For shaders (so they don´t look washed out) place
a Color correction node. And set their gama into 0.45
(that´s 1 divided by 2.2). The shaders will look nice
again.
2. For the texture files (images), go to their
"adjust" tab, find Color Profile (should be on
linear) and there for you see it washed out. Set it
to SRGB and you should see your textures in
wondercolor. :)
This is all assuming you already checked the boxes on
File>Preferences>Display>Color managment and ticked:
Apply to:
Render regions and viewports
Render pass and preview
Shader balls
UI widgets
FX Viewers.
And of course checking all your gamma values are on 2.2
Hope this helps.

I'm a virgin to the whole linear/gamma lighting
method. I'm old school and render out 8bit stuff
mostly. I noticed in reshift, the default gamma
setting makes everything in the region, render,
etc. look light and washed out. Changing it to 1
looks normal. But if I want to properly render
out exr, what should I have these set to? After
rendering and wanting to do some post work in
photoshop...what should my space be set to so I'm
seeing/working with the right thing?
