Today's photo is a combination of several ongoing themes:

1. The "Dreyfus playing fetch" action-shot theme, and
2. The "Mark is testing new photo equipment" theme

My latest piece of gear is a radio trigger for my flash units. Now I can light Dreyfus from any angle I desire. My plan was to light Dreyfus from both sides, but my Canon Speedlite 430EX isn't triggering properly. My Vivitar 283 (used for this photo) works perfectly, though.

I actually spent so much time testing the radio trigger that Dreyfus got tired of playing with me!
