Gels

How do they make backrops look? Can some show me an example? Like a before and after. I have been hearing some stuff about them and was wondering about them. Thank you.

You can use them to change to color of the backdrop.

Whatever color gel you have, the light hitting the backdrop will be that color...

Other than being a different color, the backdrop wouldn't really look any different.
