These are some water drop splash rebound effects.

These black and white photographs of water splashes concentrate on the after effects of the impact of a drop of water on a shallow layer of the same liquid. This is a recoil or rebound effect of the surface responding to the sudden disturbance caused by a drop of water hitting the surface. The recoil column of water rises to surprising elevations above the surface and then due to surface tension effects it breaks up into droplets that fall back into the host liquid under the pull of gravity.

The camera that was used for these photographs was a Canon A1 with a 135mm f/3.5 Canon FD lens with a 25mm extension tube. The film was Kodak T-Max 400 black and white film processed in Rodinal 1:25 for 6 minutes at about 72 degrees F. The lighting was provided by a Braun electronic flash set to automatic but with a piece of paper deflecting light from the flash head towards the photocell in order to quench the flash and thus produce a flash of short duration. This is required to end up with sharp photographs of this high speed event.

The timing was accomplished by using a home-made dark activated synchronizer that detected the passage of a drop across a light beam and that could be adjusted to fire the flash at some desired time after the passage of the drop through the beam.

These are examples that are available from existing negatives. If you would like a photograph made to certain specifications drop me a line and we may be able to work something out.
