Since I just stuck a link to this photo on a thread about doing IR photography, I should probably describe how it was done:

I used an unmodified Canon A650IS compact camera to record the image. I used an after-market filter adapter that mounts to the bayonet mount at the base of the lens barrel. (I urge anyone using their Canon PowerShot cameras in the field to do this, since you get the added benefit of having a metal tube around your otherwise fragile lens barrel!) A Hoya R72 infrared filter was screwed onto the filter adapter.

The A650IS will meter and auto-focus correctly under these conditions, so no other tweaking was necessary. Exposure time was close to a second, and the shot was done from a tripod.

A wonderful shot - should be pages of comments imho. I've taken a few ir's, but none as striking as this. My Canon Eos just doesn't work well with an ir filter - the exposure times are just too inhibitive.

I did this one with an A650, but I've tested the same kind of thing on an EOS 20D. It works just as well. Better, actually, because of the larger sensor. The only catch is the A650 does a decent job of metering IR, but the 20D won't. You have to manually dial it down.

But the exposure times are about the same. If I remember right, the shots that went into this were on the order of a second apiece. Any of the EOS cameras should do just as well. But as you pointed out, the exposure times really are long unless the camera is modified.
