Some very interesting things in this article; may of which I didn't know about. Thought it might help some people out.

Interesting... I skimmed the article, but checked out the image. I can understand why the first is wrong, (using a multiply blend mode with occ and direct light). But how in PS would you achieve the addition operation?

I just bought Jeremy Birn's lighting book, so hopefully I'll get a good foundation in lighting and rendering soon.

Thanks for this John

I have always complained about the overuse of AO in film and tv. People forget about spec and main key lights all the time.....nice for the peeps here to have a good read
