infrared photos?

[cartoonvillain]

Hey, does anyone know how to take infrared photos wth the canon 40d??
or even if you can.....im quite keen to try it but have had alot of trouble finding reliable info. Thanks

Two ways to do it

- Infared filters which mount on lens
- Infared slide which replaces the one over the existing sensor making it a permanent thing. Most people do this on older cheaper cameras like 350D's.

do i have to adjust WB or change things to black & white, or will the camera figure out what im doing and react accordingly?

make a custom wb by taking a pic w/ the ir filter on and set that as the wb. you can also try it w all the other wb preset on the camera. im a nikon guy so idk what wb presets the canons have

Attach the IR filter to your lens and take a picture of a very green subject (patch of your lawn, etc)...make sure that it is nice and green (no brown patches). Then, set a custom white balance with this picture as the source, and you're set to go.
