Effects of Filters

I'm doing a presentation in the near future on "filters." I am looking for a set of pictures to show how they work. Specifically, pics of objects unfiltered, and then filtered.

Anybody have any idea where I can find such?

Here is one...

This shows the effect of using an IR/UV cut filter on a modified camera. The camera had the stock filter replaced with clear glass. The left image was taken without the IR/UV filter.
