High Speed Synch Flash Info

[Arthur Morris]

This thread originally appeared in Avian Free & Wild. Scroll down to learn how to set High Speed Synch on the Canon 580 flashes. I will ask James Shadle to let us know how that works with Nikon flashes. Users of older Canon or other brand flashes will need to consult their flash instruction manuals.

In a Zodiac on a rough morning with a huge feeding spree going on and gannets right above the boat, I created this image with the Canon 70-200mm f/4L IS lens (handheld at 100mm) and the EOS-1D MIII. Evaluative Metering +1 2/3 stops. Manual Flash at 1/1 with the Better Beamer.

I went with the flash at full power because when using High Speed Synch the flash output is cut drastically.

All comments welcome; don't be shy.
