When I render a shadeless material with the color: R-0.5, G-0, B-0, And I click on the image in the Image editor, the information below tells me it is the same color as intended.
But when I open the same image in GIMP/Photoshop, the color comes out to be R-188, G-0, B-0.
When I open the saved image in blender’s image editor again, even blender gives the color as R-0.73, G-0, B-0. (I assume its the same as R-188 since 189/256 is pretty much the same)
I don’t think it’s a coincidence that 0.5^(1/2.2)=0.73, 2.2 being the system gamma for a Windows system.
So the question is , why is this happening and how the heck do I get the color I want.
This happened as I was learning about gamma and linear workflow, so I have a few more questions:
Is the problem with blender’s color picker window or the color sampler, or both?
Does the “gamma”, which I believe is stored in an image, alter the actual image data or is it just a no. stored along with it.
Does the color picker use a linear scale at all (R-128 = R-0.5, right?)
