Hi everyone, how do i shoot infrared using my new 20D? Is there a option in the camera or do I have to buy a infrared filter? If i have to get a filter, what kind should i get?
I have a 20D with a 17-85 Canon lens.
Thanks Emil

But how could we focus if we cannot see visible light?

Maybe pre-focus first without infrared filter and then add the filter before pressing the release.

maybe sepearte the exposure, and autofocus in the CF menu, then autofocus w/out filter, put on filter, and press shutter button.

You will need a InfraRed filter to cut out all wavelenght except IR
