In the past I have tried with some coloured backgrounds and various lighting setups but this time I thought I would try something different.
This time I only used an old DVD with the purple metallic surface as background to bounce light into.
I also remembered a trick from years back we used to do to create funky colours with clear plastic things. The trick is to use only polarized light and then a polarizer on the lens also.
I did it by duct taping a PL filter to my Canon 580exII flash and putting another PL filter on my 100mm macro. It took a fair bit of trial and error to get the polarizers rotated in an orientation that produced good colors. But the hardest part is getting the tiny drop in sharp focus.
A Ziploc back was taped to the top of the step ladder so it could drip water down into the tray.
Here's how the flash looks like with the polarizer attached.
If anyone has any questions on the set up feel free to hit me up via the comments or at petesphotography @ gmail . com
