I have no idea how to set up IR for 40D, but this is how i set up my Nikon D70 previously
1. Camera set to "P" mode. Fit filter (R72) onto lens. Zoom to max, on the kit lens or any lens you may use. This ensures colour reference for CWB will fill up the frame.
2. Press WB button at back of camera and turn command dial to change WB to "PRE". View this on the top LCD.
3. Press and hold WB button at back of camera. You will notice "PRE" flashing at top LCD.
4. Point camera at a bright sunlit patch of grass, press shutter as in taking a shot. Make sure you fill the whole view frame with the patch of grass.
5. If CWB is recorded in the camera's buffer, "GOOD" will show at the top LCD.
6. Done. CWB is set for IR shooting.
There is a timer in the camera when "PRE" stops flashing in step 3. Repeat the step again by pressing and holding the WB button to get "PRE" flashing again.
So everytime you want to shoot IR, just change your WB to PRE. Once set the CWB can be used indefinitely, unless you find the colors strange and want to reset it.there's also some photoshop tweeking
