Hi Kurarensu,
Thank You for the comments. I'm a newbie too....We'll learn from each other. IR is infrared. Thus IR photography means you are taking pictures using only the infrared light. This can be achieved by buying an an ir filter that will block away all other spectrum except for the IR light (which is above 700nm).
1) First of all you must ensure that your camera is capable of capturing IR.
2)Also ensure that your lens is able to capture IR without causing hotspots. (hotspot is something like a circular reddish/orangy spot in the middle of your shot) Do avoid these lenses.
Below is the thread that list down cameras and lenses that are capable of capturing IR shots.

3)Once ok, you are required to get an IR filter (an example is Hoya R72)
4) Customise your white balance before shooting. On how to do so follow the link below:

5) The picture that you see is edited. You must edit your photo. For me I'm using photoshop. Click on the link below and follow the instruction starting from no. 6 (no. 1-5 can be a repetition):
