"1. It has a first step where it converts non-linear textures to linear data."

I think you are saying here that the typical 'texturemap.jpg' is stored in gamma corrected mode.

.......

so, if I have gamma correction checked AND output to openEXR checked, does Poser import the texture files, convert them to linear, compute the render in linear, and then does NOT convert the results to gamma corrected when outputting?

[That would explain why an openEXR output looks 'way off' when you first open it in Photoshop, but looks so good after you apply exposure/channel-mix to it.]

Thanks for your patience, I am just learning.
