With apologies to Harold Edgerton (and with a little help from Mrs. Documentary Photography) here's a little stroboscopic experiment.
The setup: a Nissin 466 with a red gel on was set up to light the background, then a Metz 58 AF-2 in stroboscopic mode provided 5 flash pops at a rate of 20 Hz. The exposure was ISO 100, f/11, with a shutter speed of 1 second. (The metz was at 1/128th power.)
"But what about the purple and blue?" you ask.
The Metz was fired through a snoot to control where it hit, directed at the ball and the left side of the frame. It puts out light that is at a color temperature of about 6000K, so by adjusting my white balance setting to about 3000K I was able to shift the light to blue -- and it turns purple where it mixes with the red light from the Nissin.
