Science photographer Ted Kinsman wrote this piece on building and calibrating a photodiode-based light meter:<\/p>\n

\nBeing in the professional science photography business, I often get asked to photograph the strangest stuff using some very weird lens combinations. Lately, I was asked to take some motion pictures of "microscopic animals". So I set up the microscope and attached it to a 35-mm motion picture camera \u00e2\u20ac\u201c but how do you measure the exposure?<\/p>\n
A typical answer would be to use a standard film plane meter, but such a device would not fit my situation, and I would still have to perform a calibration on the device.<\/p>\n
The answer to my problem was to simply build the type of meter I needed and then calibrate the device…\n<\/p><\/blockquote>\n
