Spent some time experimenting with flash in the studio, trying to catch the moment a bubble bursts. I set up my camera on a tripod with a remote flash set at right angles to it, against a dark background. I had a remote shutter release as well to make it easier, but still needed 2 pairs of hands to do the bubbles, then pop and click! I set the manual focus point on the same plane as the flash head, and exposed to be black with no flash, so you use the flash to expose the image which allows you to get these fascinating shots of things too quick to see by eye. After going through 2 bottles of bubble liquid it proved quite a task, but once you get a bubble to drop in the correct focus plane I used a long screwdriver to pop it and pressed the shutter release at the same time. After a lot of trial and error, its amazing to see the screwdriver piece a bubble just before it pops, and the moment of explosion as well as the sphere breaks up, looks like something either from outer space or the deep ocean, but beautiful as well. A great technique for doing water drops/slash, drinks spill etc, and fun to see the results.
