Full disclosure, I suck at figuring out linear/non-linear workflows. God knows I've tried, but I'm a concept artist so 95% of the time I just need pixels from 3d to mash into 2d workflows.
But I'm working on a heavy 3d scene which is sent to a render farm and outputs EXR files. In the Vray Frame Buffer I have sRGB off and I get a my desired gamma/contrast in the frame buffer. When I save out as EXR it's like the sRGB is turned on i.e. really pale and bright.
All I want to know is, in Photoshop, how to I get it from 32 bits to 16 and get that exact same gamma as in the frame buffer. Currently, non of the option in the HDR toning dialogue are a good fit. They alter the image too much.
