This was a fun one I did tonight... Post pics and how you did it. I used a "moss green" HONLPhoto Gel w/ an on-camera 430 EX II Flash. My wife was taking some pics at my daughters birthday party so I set-up up a Rebel XSi with a 50 f1.4 and the 430 EX II... a nice light rig that takes excellent quality pics.
This was handheld 1/5th of a second expose, f2.8 Aperture priority mode, ISO 800, was very dark inside... the AF barely worked.
