One of the tricks my new expensive speed light (that's snooty SLR-camera-owner-speak for "flash") lets me do is strobe photrography: having multiple flashes in the same photographic exposure. For lack of a better subject, I've returned to photographing coins in motion, this time dropping them onto a hard wooden tabletop. Each of the photos below is a result of having the shutter open for 0.04 seconds and firing a flash four times at 100 Hz (one flash every 0.01 seconds). This being my first attempt, I am quite pleased with the result. I can't decide if I like the blurring between flashes or not. The room was quite bright when I took the pictures. Repeating the experiment in a dark room would, in theory, remove those "between flash" bits. I'll have to try that next. I've ordered them more or less in order from the one I least like to the one I like most.
