next, previous Section / Table of Contents / Index High quality reproduction of the graphical (color screen) output is, apart from PostScript output, possible by simple photographic procedures which may in some cases yield more brilliant pictures. This requires e.g. a 35 mm SL camera with or without automatic exposure system and a heavy tripod. To obtain good results note that - the screen should be located in a room with few additional light sources. During exposure no external light should reflect from the screen. This is particularly important if structures on black background are to be reproduced. - the exposure time should be large enough (typically > 1 sec) to overcome the screen refresh cycle. Otherwise, the reproduction may contain stripes. next, previous Section / Table of Contents / Index
