Off camera flash

I've always been rather unkeen on using flash on my photos, preferring the look of natural light. But from doing my research it appears that the more I can get to grips with using flash, the more possibilities it opens up. I bought a flash unit which I can attach to my camera, but more excitingly, which I can take off my camera and place it to light up the subject from whatever angle I like. One of the things I decided to try with my new light was a back-lit photo of some watery subject. The flash duration is so short that you can capture each of the tiny droplets and bubbles very clearly. I positioned the flash to bounce off the wall behind the glass so that the liquid is illuminated.
