[QUOTE="WayneF, post: 166459, member: 12496"] Not sure, but I read that bees wings might be closer to 200 beats per second, but 1/500 second is still too slow. But yes, speedlight flash is THE standard High Speed photo technique. Camera flashes are called Speedights, because at lower power levels (like 1/32 power level), the flash duration may be only say 1/20,000 second (durations are normally printed in the spec chart in the back of Nikon flash manuals). At say 1/4 power, you might still expect 1/3000 second duration, but full flash power might be 1/300 second. See [url=http://www.scantips.com/speed.html]Capability of flash units for high speed photography[/url] Speedlights are definitely the only way to stop hummingbird wings. Also used for milk drop splashes. You would underexpose the ambient a couple of stops so that its continuous light does not blur the motion, and then use the speedight at low power (up close) to stop the motion. [/QUOTE]
