Default Re: Using Gels To Change The Background Color
JG,

"Let's say I wanted a photo with a background that has a heavy blue tint to it. No problem I would just throw a blue filter on my lens. Now if I add a model and wanted her to NOT be blue, could I put an orange filter on the flash so that she comes out "normal"?

Theoretically yes. But getting the flash unit to illuminate only the subject could be a problem. I remember seeing a technique years ago "invented" by Larry Peters where he put three flash units several inches apart beside the subject, one red one green one blue. Each cast a shadow of its color only so where they all overlapped each canceled the colors of the other two out and that part was correctly lit!
