Time for a ghetto tutorial. Using a CD jewel case we'll make a nice gel light.
This is an older tutorial that I posted quite awhile ago. I apologize for just ripping it down like that. Having said that, let's get on with it.
I was desperate for a color light tonight. I didn't have one and I was too lazy to go to the store (it's like 1:00am on top of me being lazy). So what to do, what to do.
I'm sure you have a color jewel case or two laying around?

Take it apart and tape a few together like so.

Then set it up like so.

Then take a photo like so.
Do NOT use the term ghetto unless you're trying to refer to a high density, impovershed section of a city inhabited primarily by people of the same race, religion, or social background, often because of discrimination.
It shows your class and race, which, lets be honest, is unbecoming of you.
