ive come across it. With digital its kind of a lot of work. You'll need the IR filter and a sturdy tripod like bogen/manfrotto, benbo etc. for those long exposures, even if the tripod ends up weighing a ton its a good investment if you pursue long exposures. Thats also why most IR shots are scenary, people just cant sit still that long. Even the slightest wind of a IR shot of a tree will blur the leaves a bit. Also you'll have to compose and manually (or auto) focus your shot before placing the filter on because once its placed you wont be able to see what youre photographing through the viewfinder. And because of the filter and the technique itself you may have to overexpose a bit for the end result to be properly exposed (if you know what i mean).
I think thats the most of what i know about it. I believe there's more to it like certain lighting conditions etc but like all things once you get the hang of it it wont seem like so much work.
and like digital BW, digital IR is often overused for shots where their lighting/tonal range is best left unaltered.
good luck!
p.s.
I didnt get a chance to click your link but I moused over it and saw its wiki. although wiki is awesome, most of their articles are composed by different sources gathered into one, very little are from first hand experience. Try searching or even posting your inquiries on photo.net. Their forums are extremely informative and you can usually already find a topic already posted about what youre looking for. Of course Im not saying dont post here, im just letting you know that if you cant find the answer here you will most likely find it there.

Jonny, with digital photography I haven't yet tried it, but I read from Vahephoto he bought a second hand Canon 20D (mine ) which is the one to be changed into a specific IR DSLR camera! Changed! This means it will only do it from that day on! Maybe you can email him and ask for details!
(Oh, you are going to have a big trouble when you say there's no limit of pics to this very first NFC (New Fortnightly Challenge ) ! And that in future the limit will be 10 per member!!! Think that next juries may not have time to see and choose, for instance, 10 X 60 members!!! Don't you think a limit of 3 pics per member, from the next one on, will be the right thing?! Think of it) Oh, I like this very first NFC!
Greets,
Miguel

Hi,
Miguel already partially answered your question, and Leilani gave a very detailed answer on IR filters, but let me fill you in on how i've approached this.
I used to do a lot of IR film photography, but the impossibility of carrying IR film through airports made me abandon this... I didn't want to use IR filters with a digital camera, mainly because of the limitations that Leilani mentioned. Then, about 6 months ago, I heard of places that converted DSLRs (and some point and shoots) to IR. The one I chose after a lot of research was lifepixel (www.lifepixel.com). As Miguel said, I bought a used 20D and sent it to them. It cost $400 to have it converted, and I chose the "Deep B&W IR" filter. What they do is take out the filter that blocks out IR from the CMOS sensor and replace it with a filter that only lets in IR. Even with the deep IR filter, you expose at normal speeds (I usually find that i have to overexpose one stop), which means you don't have to use a tripod (I usually do). You may want to look at some of the photos I've recently uploaded, as I have posted about 20 photos that Ive taken in the last several months. Please feel free to email me if you have any questions!!!

Hello Klaas,
I have used the Hoya R72 IR filter in both my film slr (Praktica BC1) and with adaptor ring for the present digicams. Here is a link on the use of the filter from "Digital Photography for what it's worth" :

Hope it is of use.
Best regards.....sawsengee
