I just got my Canon EOS 350D and a Hoya 72 IR filter. When I attach it, all I get are black pictures. Sorry for being a noob, but what am I supposed to do?

Take much, much, much longer exposures. There's an infrared filter over your sensor, and the R72 is actually a *visible* light filter (it's called an "ir filter" because it's for use in IR photography, but it's actually the opposite of that).

So the only light that your sensor is getting is stuff that sneaks past both filters. There won't be much of it, so you need to use looooong exposures.

Digital camera sensors come with Infrared filters already. So, if you use an extra filter than only lets IR get through, you'll get dark exposures.

Basically, to get any exposure from IR at all, you'll need to crank the shutter speed way up.

Try bumping the ISO as well... and using a larger aperture.

If that doesn't work, you're fucked.

This looks exactly like the pic I took a week ago when testing my new/old Industar lens. HOW DID YOU GET A SHOT OF MY POTTED PLANT?!

Was this 30 second exposure in bright sunlight?

Might just be that the IR filter on your 350d is too good.

Take off the lens cap.

This is a good idea, too. It's a pretty advanced technique, but once you get to be more of a professional you'll find that it makes your pictures a lot more vibrant and interesting.
