Fast photometry is measuring changes in brightness in the range of several seconds down to a few milliseconds or faster. Increasingly, asteroid and lunar occultation measurements are carried out using camcorders or video cameras. These can be very inexpensive, and allow event timing to about 0.02 sec. GPS timing signals, good to a microsecond or better, can be combined with video or photometers to allow UTC timing to as good as the sensing device allows. Beyond video cameras that are usually limited to event timing, there is also a role for amateurs to explore true high speed photometry. I will describe use of several inexpensive devices that allow an amateur to conduct fast photometry. I include observing results from this equipment as used in occultation and scintillation studies, and will discuss some of the possible areas of amateur work.
