AboHadi, thanks. These are lit with two flashes, placed very close on either side, one almost directly above the drop. I play a little bit with the angles, but keep the powers about the same.
It will work with the components I listed above, and it is pretty easy to plug them together (seriously, I know nothing about electronics). The HiViz kit is aimed at high school students, and this Arduino-based set up is ten times easier than that (but twice as expensive).
Thanks for the reply.. I will attend to this once my thesis is finished!
Just one question about your flashes.. I noticed you mention that you use Vivitar.. If I buy two, would they be adequate by themselves? Or I would need a main flash like the Canon EX580 II? BTW, I use Canon 7D..
I might bother you again in a few weeks when I order the components and try to put them together!
Many many thanks, AboHadi
P.S Are those taken with a macro lens? What's the aperture?
Two flashes would be adequate. One flash is also adequate, but is much harder (requires pushing the ISO, lowering the aperture, and a lot of care in setting up reflectors). With studio flashes, the question is probably whether you get the flash duration low enough. I don't have any real information on this, but I doubt it would work.
I am happy to help, but please send me an email if you have other questions.
Thank you, Lil Judd, SJMD, Timberland and galadial. I appreciate the feedback.
A next project I'd like to try is to set up a rotating mirror next to the drop target area, aim the camera at the mirror and trigger the flashes multiple times, in order to get multiple exposures of the same splash in a single frame. Controlling motors and stuff is way beyond my electrical abilities right now, but if I ever have some time...
