Default Using gels to change the color of the background...

Is it possible to use gels to change the color of the background? And if so, what is the best technique to do so?

Can you be a bit more specific? Sure you can change the color of the background as long as you have a surface to project the geled light onto or into.

Sorry, I should have mentioned that I will be using them on a white seamless paper. Does anyone have an example of pictures they have taken using gels to change the background? And where is the best place to get the gels?

There's so much on the site that I'm not sure where to point you as a start...

I guess start with the links in the "Similar threads" section at the bottom of this page.

I'm using the little lastolite gel holders on my speedlights. They come with a basic assortment of gels and don't take up much space when I'm not using them. For the gels themselves, many people like to the little sample packs because the small sample gels are the perfect size to put in front of a speedlight.

It's a cool feature but it's at the bottom so most people overlook it.

You'll get much better results if you use a darker color background. The white will be too reflective.

Here's a recent thread with some good samples. Notice that the background is gray, not white, for the reasons jra mentioned.

The background in this image was nearly black. I used a red gel over the background light & moved it rather close (like 2 - 2.5 feet) to the BG so the edges would go a little darker.

Also there's the trick of gelling your main lights and using natural or ambient light in the background and then shifting your WB. This works to give only certain color combos though, but you can use it in situations where your shooting against an open background as opposed to a studio type backdrop or wall.
