For lighting EXRs and HDRs should be interpeted as linear. That said,
sometimes I'll cheat things a bit if I'm using a dome light that isn't
visible to camera and bump up the gamma slightly, which can give some
interesting results lighting wise. Just depends.

Thanks guys...some good stuff here! So what about environment
lighting...hdr/exr stuff...linear or sRGB for that?

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?
