Tonight I explored high-speed photography using little more than a couple flashes and some coins dropped into a glass of water. It took a bit to get the timing down but I got some pretty cool shots. Eventually I'd like to use something more flat glass (rather than a round cup) to better be able to focus on the subject rather than have the light be bent all over due to the shape of the container.
My first high-speed shot. Decent but needs more light -- 2nd flash to the rescue!
Those crosshatch ripples freak me out
Kinda' looks like a liquid metal skull to me
The tip of the quarter iceberg
I love this because you can see the floor of already dropped coins reflected in the bubble
Love the vortex and twist in this one
Then, for the heck of it, I added a red filter in the form of an old medicine bottle :)
