Oh - it is so easy to make Infrared Photos. Most of the ir photos are made with normal digital cameras and an infrared filter which you simply screw on the lens.
With some cameras it is easier to make infrared images - even hand held - because they have something like a "nightshot mode" like certain Sony models (f.e. F717 or F828). Or they are technically converted into an infrared camera. That means that someone has removed the internal infrared blocking filter.
With some other camera models it might be a little more difficult to make good infrared photos because they have inside stationary strong infrared blocking filters on the chip for a better color management of the camera. Some camera models or some lenses may also produce a big white "Hot Spot" in the center of the photos. E.g. to make some good IR-Shots with a Canons seemed to be more difficult. You have to expose at least 30 Seconds and more even in the full midday sun because of that strong internal infrared blocker.
Most of the Nikon models produce better results. If you google your camera model plus the word "infrared" you may find some sample pictures and descriptions whether your camera "is ready" for infrared photography and how to use it correctly for this technique. All you need is an infrared filter (and maybe a tripod).
There are many different types of Infrared filters. I am using 1 x Hoya r72 720nm (most ir-photographers are using this type of filter) and 1 x noname 950nm filter. A filter with 720nm is good for some day light + infrared light mixture. With a color editing processing (blue-red channel changing) the results are very good. If you are using a strong 950nm IR-Filter all visible daylight will be excluded - totally excluded! So the results are more monochrome like in black and white photography.

and in Gilad's journal -->> [link]
We have also a photo gallery with analog infrared images which are made "traditionally" with Kodak (and other) Infrared films -->> [link]
You see there are variety of ways to make infrared photos. But all those photos seemed to be more or less surreal and show us rays of light which we can not see just with our normal eyes view. And very simple photo motifs will suddenly change with infrared techniques into a magic world. It's easy to learn and you will have good results soon. So just give it a try!
