That optimization could potentially make things worse. This involves an indirect data look up which can be slower than simply a couple of predicated moves.

I'd be happy to take you up on the offer. I have about 30 years graphic programming experience, 20 years of that professionally.

I am based in Vancouver, Canada which is -8GMT so not sure if that works for you with your location.

float exposure = key * L / avgL;

 

change it to 

 

float exposure = key  / avgL;

 

I don't see why you need the multiply by pixel luminance
