Caring About Composition
quote: "Scope" Is Meant to be Wider than "Flat"
Filling the full width of the screen for both 2.39:1 scope pictures and 1.85:1 flat pictures is almost as bad as "one size fits all" screens. This poor practice has become a popular trend in modern theatre designs, especially those with stadium seating. The misguided idea is to fill the front wall of the theatre with the biggest image possible, regardless of the intended format. So instead of maintaining the same image height for the scope and flat formats by using adjustable side masking, both formats are projected with the same width. The top and bottom masking are adjusted to letterbox the scope format, and actually project a much smaller image than the flat format.
What's wrong with this picture? Plenty! First, the wider 2.39:1 scope format is usually chosen to give pictures greater impact, than the more intimate 1.85:1 aspect ratio. Letterboxing it to a smaller image often violates the intent of the cinematographer and director in telling a big story.
Image quality of the flat format suffers in comparison to the scope format, especially when common width screens are used. The projectable image area of the 1.85:1 flat format is only 65 percent of the much larger and efficient scope format. It makes no sense to project the much smaller flat film image area on the print to a much larger picture than scope on the screen. It simply magnifies the grain and greatly reduces the light level. For example, a theatre that is getting the SMPTE aim of 16 footlamberts for scope on a 25 x 60 foot screen, will typically get only about 13 footlamberts for the less efficient flat format on a 25 x 46 foot screen, which is still within the tolerances allowed by the standard. But if they try to magnify the flat image to fill a 32 x 60 foot screen, they will only get a sub-standard 8 footlamberts, since the light must be spread over a much larger screen area. When you project flat and scope films to the same width on the screen, bigger is definitely not better!
