HDRI Metrics

Sign in to follow this  


So, I've been thinking about tweaking some of the mtrics used in the HDRDemo code.

I've seen, as I'm sure you have, some pretty breathtaking HDRI-related shots..

But in my recent investigation into such things, it's shown just how many parameters are involved. So many things that make a difference [headshake]

Consequently, it's difficult to get things looking how I want. Part of that I've now come to appreciate is due to the test data I'm using - it's fairly polar, either very bright or very dark. Not a lot I can do about that now

Anyway, check out my thread in GP&T for some screenshots of what happened when I messed with the RGB->Luminance calculations [smile]
