I have a 32-bit EXR image that's supposed to show the following color:
r: 0.5 g: 0.5 b: 1.0
each color channel is in the [0, 1] range. When I open the EXR file in Photoshop, this is what I see:
You'll notice that the color picker accurately lists
r: 0.5, g: 0.5, b: 1.0, but visually it's much lighter than it should be. A color of those values should look more purple, like this:
The problem is that I need to take the 32-bit EXR and convert to 8-bit PNG, but it's coming out much lighter than it should. Instead of getting the color I need
#8080ff, I'm getting the lighter
#bcbcff. Do I need to do gamma correction, or some sort of linear-space conversion? I believe this question is very similar to this question for GIMP, but that one doesn't have an answer either.
