cobaltdream... I have an sRGB output correction shader, based on the sRGB shader that BB posted for his Artistic Lens (over in that thread).

I replaced the Artistic Lens nodes (Refraction and HSV) with an input node to plug in the linear value to be corrected, and tidied up the layout so I could see what was happening.

As it's basically BB's work, I'm not sure I should post it. (?)
