At 60 Hz, they'd be pulsing at 120 times per second, right? Once for the "up" part of the cycle and once for the "down" part (thinking of a sine wave here)? And, yeah, I'm pretty sure I was shooting at 1/30th, so that would be 4 pulses for that period of time, right? Sounds like a sound theory to me until something better comes along. thanks, frank -- "Sharpness is a bourgeois concept." -Henri Cartier-Bresson
