Adobe Photoshop CS3 includes a black & white feature that transforms the colored picture into pretty realistic infrared black and white image.
From the Menu Image -> Adjustments -> Black & White (or Alt+Ctrl+Shift+B). In the Black & White Tab select Infrared. Now you can decrease the RED channel even more (and increase the GREEN channel) if you want the greens to be closer to white. The image after this step does not yet look like a perfect infrared, but by adding more contrast to it (until the green becomes white), you get it right. The result is grainy due to the high contrast. You can uniform the grain by adding Filter -> Texture -> Grain, and then desaturate the image. Or, you can choose to remove the grain with Neat Image plug-in.
