I just got a red filter as a birthday present  and I'm trying to adjust some images in PS to get that blue and white effect. can anyone please explain how it's done or send me a link to a good tutorial, because I've been looking and I can't find anything. thanks.

What I do is basically a swap in in the red blue channels.
In Photoshop:
Image-->Adjustments-->Channel Mixer-->
in the Red channel take red to 0 and Blue to 100
in the Blue channel take blue to 0 and Red to 100
I shoot IR with a camera that I modified by removing the hot mirror and replacing it with a an IR pass filter. (FWW the next one I do I'll replace with clear glass and mount the filters outside of the camera. That would let me explore UV and IR Notch filters) The reason I mention what I shoot with is because each filter has a different look and on mine the contrast is very low but the image is very sharp and the exposures are about equal to normal exposures. With an unmodified camera the exposures are longer and I'm not sure what the contrast range is.
I'd be interested in what an image comes out of your camera looking like. Any chance you could share one with us?
One thing I'd like to do, and can't because my camera only shoots IR, is to take two images exactly the same one IR and the other normal then use the IR image as a layer or mask to modify the normal image. Specifically I'm wondering what happens if you use the IR image as a Layer and blend it using luminosity. I'm betting you could come up with some pretty cool stuff.

Basically... I tried doing several things and finally realized that my camera (DUH) is not IR sensitive. I don't think I want it converted, though... thanks for taking the time to help me, guys, much appreciated...

Before you decide that. Point your tv's remote at the lens and press a button. If you can see light then it's ir sensitive.
