Rolls Of Film: Thousands of film rolls were inspected; laboratory equipment used included the electron microscope; laser-beam probe; and ultramicro-tome, which splits the film into extremely thin transverse samples. Computers evaluated the data produced.
A chemist at the NBS traced the cause of the blemishes to gases produced by the paper boxes in which the microfilms were stored.
(which netted him $20) and he scheduled all eight sittings to take place in the two hours between 9:00 A.M. and 11:00 A.M. This made a well-rounded working day for the photographer. He could arise, have a leisurely breakfast and drive to the first sitting by 9:00 A.M., work hard for two hours and go home. Then he could relax, have lunch, and develop the eight rolls of film he had shot. Using multiple-reel tanks, it was possible to develop all the film in less than an hour. The use of deep tanks would make it even faster.
Speedlights flash, the picture is taken, the film automatically advances, the shutter is cocked, and all is in readiness for the next child in the line. Similar cameras are available which operate with 35mm film. The smaller film cuts costs a bit but naturally the contact prints are not so appealing as those from the larger film.
