So I have a new project. I went to Walmart (gag) and picked up some Avery "Insertable Plastic Dividers" Basically colored folder dividers. They are made of light see-through plastic. I have two ideas for using them. The first is to buy a blank thread on filter for my camera. (do they sell blank / clear filters that don't affect the image? Then I'm cutting a (72mm) circle of the colored plastic and will put it behind the blank filter. What's cool is that since my camera has the 1.5x crop factor, the edges of the plastic don't have to be "exact" just close enough.

My second project is to tape the colored plastic over my flash. I basically have filters for my flash. Turn out the lights, pop a few photos and enjoy. I've also thought of putting these over my flashlight to make a colored spotlight for my night photography.

Weee!

**edit** okay the optical quality of the plastic is too poor, but the flash and spotlight are good to go.

I did something similar a couple years ago. I just used regular transparency sheets (for some reason I have hundreds of them) and printed big colored squares on them. Then I made holders out of posterboard. I only use them with my spotlights though.

If you want a bunch of colors to put over your small flashes there are swatchbooks that are available for free or nearly so.

Here are links to two you can order for a penny.

I probably wouldn't recommend using found plastic as photo filters,. but if your going to do it,. skip the round and get a square filter holder. Probably a lot easier.

Actually as long as the flash is the only lightsource, I think it's pretty much the same as using a color filter. Here's my results with flash.

I thought about this before upon seeing those in the store once. I decided to go another way and make a "white balance card" that would emulate the different filters. I still have it and need to update it with my new printer (and the colors a bit) and for my D70. Definitely is fun. But now what I am shooting much more in RAW it is easier to use the tint and Wb slider.

Colored gels over your flash/spotlight can be very much more creative than just having an image of all one color and impossible to duplicate with just an altered white balance.

Troy Paiva of Lost America really impressed me when I first saw his photos. He really shows there is a lot you can create with some inexpensive gels and lights. I originally found him through The Nocturnes website. A great collection of night photographers and photography. I'm also impressed with another artist featured there, Michael Frye. He often uses some slightly more advanced equipment and his photos are just amazing.
