Well that's a start. Taking IR photos with a film camera is no easy task and it is very very expensive to buy the film and process it. Using a digital camera is far easier and cheaper.

OK, the first thing you need to do is find out if your camera is IR sensitive or not (digital cameras).
With a point and shoot camera aim a remote at the camera and press any button. If you see a blinking white light then it's IR sensitive. The method for a DSLR is a bit different. Go into a dark room and manually set the camera for a 30 second shot with the aperture wide open which is probably F2.8 or 3.5. Fire the camera and hold the remote in front of the lens while holding any button. Once it takes the picture then preview it and see if you can see white flashes or trails. If you can then it's IR sensitive.
So if your camera is IR sensitive then the next thing you need is an IR filter. The most common filter is a Hoya R72 infrared filter or equivalent. The 72 filter blocks all light under 720 nm which is the threshold between IR and visible light. A 650 nm filter is cool for color IR because it allows some visible light to enter the picture and the results are bizarre to say the least. There are filters that are in the 900 or 1000 nm range which are really really cool for pure IR but they are expensive and it's a real bitch to use them. Super long exposures and high F stops equals giant headaches. Anyway start with a 72 filter and worry about the rest later.
Now the fun part, taking the pictures. For now I'll talk about black and white IR photo taking because it is far easier to do than color IR. First afix your filter to the camera lens. Turn it on and go into manual mode. Set your camera to take B&W images, ISO 200, white balance to auto or 5500K, shutter at around 15 seconds and your F stop at around 11. Oh yeah, a tripod is required. Focus the camera and fire away. In bright sun this will give you a starting point to work with. Adjust shutter speed and or F stop until you get decent images. One final thing, IR focuses ahead of normal visible light so keep that in mind if you're trying closeups. If the camera won't focus then go to manual focus and set it to just shy of infinity for scenic shots and you should be OK.
Color IR is an animal but well worth it if you can tolerate setting the camera up and doing the post processing. Here's an idea of how weird it is. My white balance for the pics above was 2500K with a Green 9 filter tossed in. The WB in color IR changes during the day and from scene to scene if there are clouds or haze. My camera has a manual WB mode and it eats whatever I feed it which makes my life a whole lot easier. If you cannot manually set the WB then don't even bother with trying color IR.
I'll explain how to do color IR photography and post processing if you really really want me to. It might take me a day or two........
