Thanks genny, im glad you think so. I heard this scene is from an old challenge. Might get involved in all that if i find time at some point. I meant to say to you, i guess you have seen boaz linvys advanced photorealism in mental ray course on cg? It has a section on gamma correction and all that linear workflow business. Id like to take it too,but have got so fed up with not having time for my own projects, want some time to put into practice what i have learned from the matte painting and lighting courses. Hope to talk more lighting with you in future.
