Additions needed are the difference in frame sizes for different kinds of projection. On the same 35mm fiim, there are a wide variety of frame sizes. Vistavision uses a frame size which is similar to 35mm still photography which is 90 degrees from standard motion picture frames and the film runs horizontally, not vertically like regular motion picture reels. Also, the history of the different frame sizes needs to be added.
What is Wikipedia policy for individual film frames of a work protected by copyright? I've seen elsewhere that showing less than 4% of the whole thing is considered fair use, but it is not an official source. I ask because I think it would be important to include in this article and it would help editing of other articles. If anyone can point me to a policy page where the answer can be found, I would be grateful. —Preceding unsigned comment added by 22.214.171.124 (talk) 00:44, 1 August 2008 (UTC)
