Anyway, I recently got the urge and had the camera out, with my flashes. Originally, I wanted to paint harsh edges on the boombox with light, which is why I chose the colours I ended up using; I wanted it to look like a 3D anaglyph photo from the 80's.
Then, I had the bright idea (pun intended) of placing the flashes just off camera and shooting the light into the lens on either side. This was tough to balance, since that drastically reduces contrast. I think this retains enough sharpness while still getting that disco-lighting feel.
Yes, I know there is dust and some scratches, I cleaned it up as best I could.
"80's Dance Party":
85mm @ f/9, iso400, two gelled, off-camera SB-600s triggered via CLS.
For comparision, here is what it looks like in real life:
YEAH BOIIIIIIII, PEACE!
