So this is what I was trying to do when the little water monsters appeared. In my continuing efforts to do anything but study for exams, I decided that it would be an excellent idea to try out some more high-speed photography using my flashes. The setup was simple: A bowl of water with a sheet of white paper behind it, and then one flash pointing at a 90 degree angle to the camera, and a second one bouncing off the wall for a bit of fill. I then focussed the lens (Sigma 105mm Macro) using trial and error, which is a bit infuriating but I don't think there's any other way. This is definitely 'proof of concept' (a great term for when something turns out a bit shit...) rather than a finished idea. If I wanted to do this properly, I'd need a larger container, and one that wasn't rounded: this caused a lot of distortion and difficulty focusing. Still, it was fun, and it certainly helped me in my quest to under-perform in my exams! Which is all you could ask for, really.
