Water drops
Spent some time getting to know my new tripod tonight. 50 or 60 shots later and a very wet kitchen counter top, I came up with some reasonable results for a first attempt. Nothing too fancy used, just a pint glass of water, a blue paper bag as a background, my trusty Nikon D100, 70-200 lens and on-camera flash.
I actually set the camera to 5 second timer, press the shutter release, then let it countdown while I slowly let water drip from a small plastic water bottle from a height and hopefully when the flash fires, it captured something interesting.
Into The Vortex
This was a complete accident, I'd set the self timer off whilst the camera was on the tripod, as the shutter released, the tripod head slipped and went from vertical to horizontal creating this circular view!
