The first one was a rehearsal of a musical performed by 2 actors/singers. It was in a hotel lobby and the lighting situation was really F-light: on one hand, day light coming from windows (but not enough to make the picture printable by our old print press); on the other, fluorescent lights on the ceiling and incandescent/energy saving lamps on the tables. Decided to do my own lighting with two flash units I had. One on camera, bouncing off the ceiling for overall lighting. The other one, a slave, sitting in front of the piano and bouncing off the music sheet, to light the singers' faces.
The result is not too bad, and this is the pic I chose for publication. Only after having turned it in, I realized that the flash unit was visible! but only after a second or third look (it's sort of camouflaged by the piece of furniture behind it, and I hadn't even noticed it while toning the picture!). Did you actually noticed it?

The other assignment, on the very next day, was at a country music bar that has family-friendly karaoke on Thursdays. I swear the only lights there were those little christmas bulbs, which is to say: there was no light. I needed to capture the "family atmosphere", and that implied more than one layer. I put a slave unit on top of one of the amplifiers to give some light to the stage (you can't see it: it's behind the lady) and used the unit on camera to bounce light off the ceiling on the lady dancing with her grandson (funny: I didn't know it at the moment, but the guy singing on the stage was her boyfriend... all in the family, I guess).
THANK YOU RITA!
