Day for Night
I agree that day for night is a lot trickier than it might seem at first but if you can get a hold of aftereffects there's quite a lot you can do. if you know programs like photoshop, then the learning curve isn't too bad. best to do tests first in a variety of different lighting...
My Two Cents
Hi All--First post here. I have always HATED 3d. Not just disliked, but really truly hated it. With Avatar tho the 3d was the ONLY thing I DID like!
The use of negative depth instead of just stuff flying off the screen was really good i thought. but i didnt care much for the story.
