I ran out and bought some colored gels thinking that I would simply place them on the front of the remote flashes and bingo I would get that color on my background. BUT it did not happen. I placed a bright blue filter on each of the remote flashes and proceeded to take some photos. Na da. Nothing changed. I changed the power output on both flashes and still nothing. I did notice, however, that when I pushed the test fire button on each that I could indeed see color on the background. So, do you have idea as to why I can not get the camera with the flashes to register any color? I know there must be a simple explanation but I am confused. Thanks, Denny.  |
My best guess is that the pre-flash fires the other two units which are still recovering when the main flash fires. A white background does not work well with gels because they reflect the light rather than absorbing it. Placing a blue gel on a flash that is positioned behind your subject and using a white background will result in a light blue background and a blue halo around your subjects expecially their hair.
