I’ll start this rant off with my usual disclaimer: Artistic Intent, I don’t care what you do to your image provided it was Artistic Intent. Backwards, inside out and purple…fine if that’s was your intent. It’s when you did it because you didn’t know any better, that’s when I have a problem and I’m here to help.
My two biggest pet peeves in HDR images are; Halos and Gray Clouds that should be white. The funny thing is, most likely the same thing is responsible for both.
