Does it exist? My local camera shops look at me like I'm speaking gibberish...

Well there's Ilford SFX - not a true IR but black and white with extended IR sensitivity.
There's also the Rollei/Maco type...

Yep, get a nice beechwood box of Rollei IR B&W film from here. Or even Ilford SFX200, which is sort of a halfway house between visible and IR that doesn't need loading into the camera in darkness.
The shop wasn't Je$$ops per chance?

Yes it does - just. Genuine IR film is quite hard to find since Kodak stopped supplying its high speed ir film which gives a wonderful ghost like quality to some subjects. A new IR film - MACO IR 820C is available but I haven`t tried it. Both these films require complete darkness for loading etc. So as I am still getting to grips with medium format, I opted for Ilfords SFX200. This is sensitive to some IR but also visible light so you have to use a filter such as a HOYA 72IR filter to block out the visible light. I`v shot 4 rolls and am reasonably pleased with results. The film can be loaded in normal conditions making it easier to handle than the purists IR film.
By the way Ilford SFX 200 is b & w, - I`ve used the 120 format.

Doubt it - they don't have many branches in the US, I think...

Yeah, richmond virginia, USA. The HOYA filter will be a trick, as I'm using a Yashica-D, granted it's a Bay I filter set (compatible with Rolleis) but can you get the HOYA filter that small?

There used to be a Rollei IR filter available in the three Rollei bayonet sizes. There is/was also a Cokin adaptor available, IIRC.

SFX200 through a X8 (+three stops) deep red is not terribly impressive. However, use the recommended very dark filter supplied in the SFX trialpack and it's a different beast. VERY much more dramatic. The filter is almost opaque to the naked eye- but on a TLR that's no problem.

Try the B+W 092 which is very dark red; the 091 is a deep red (equivalent to Wratten 29, which is deeper than the usual W25A which is what the Hoya red filter is); you can also get the B+W 093 which is a true "black" IR pass filter.
The short wavelength 50% transmission values for these filters are, approximately,
W25, 575nm; W29/B+W 091, 610nm; B+W 092, 650nm
The B+W 093 transmits less than 1% at 800nm, rising to 88% at 900nm (according to the manufacturer's website).
It is unlikely that CCD/CMOS sensors of the type found in digital cameras will have much response to wavelengths longer than 900nm even with the anti-alias/IR blocking filter removed or replaced by clear glass.

Beejaybee-
I'm a newbie at photography, would you be so kind as to put your post in english please? 
Is any of what you are talking about available for a Bay I attachment or filter size for a Yashica-D?
Thanks

Does the taking lens on your camera allow use of a filter? If so you can probably get a filter system from Cokin or similar which will allow you to use the Ilford SFX filter mentioned earlier.

I think you'll find the Maco film is off the market and Rollei infra-red, which seems to be fairly similar, is now the one to go for if Ilford SFX isn't dramatic enough. The Rollei film is finer grain than SFX.
Incidently I wonder whether anyone else has tried loading the Rollei film (35mm) in deep shade out of doors rather than pitch black? I did, as an experiment, and could see no sign of fogging after I developed the film. What have other people found? I did make sure that the cassette didn't spend any unneccessary time out of its container of course. I haven't tried the 120 version yet but have just bought a film to try with an old TLR.
Incidently I never had any problems using plastic developing tanks or plastic cameras in the days of the much missed Kodak product, despite the warnings one used to read in some places. However I most certainly did not try loading that one in anything except complete darkness!

Yes, the Maco IR820C has long gone, there was 2 versions, and the Maco/Rollei film that replaced it was quite different. But Since last year Efke/Adox IR820, very similar to the original Maco is on the market. Not as fine grained as the Rollei, slower, but more IR sensitive. All need at least an R72 filter for a good IR effect. Personally I find a Heliopan RG715 opaque filter works very well, no problem when used with a Mamiya TLR.
The 120 version of the Rollei and Efke IR films can be loaded in subdued light, I've done this in the boot of the car and in the shade behind a church and in a bus shelter. Not so with the 35mm version. The base of the Rollei film is very thin, when using the 4x5 version its dead easy slipping 2 sheets into a film holder without realising until you count up the sheets left and find a discrepancy. I've bought these films via mail order from both Silverprint and Retrophotographic.

Steve,
Did you actually try with 35mm and get fogging? I did try and no fogging resulted. Perhaps I was just lucky that time. It would be most interesting to hear other people's first hand experience.

What's the problem here? The cassette is just as opaque to IR as it is to visible light... and I can't see that the tiny amount of IR emitted by a body at ~20C can possibly affect the film, in fact it would be fogged anyway unless the film storage before & after use plus the camera were continuously refrigerated if black body radiation was a significant problem.
It's always best to load film in subdued light (*), direct sunlight is asking for trouble by fogging through the film slot in the cassette or past the spool ends for roll film.
(*) Except for sheet film, where full blackout is mandatory irrespective of film type.

It's the felt light-trap that allows IR to pass more than visible light, apparently.

Nick, yes- my understanding is that the felt light trap is 'transparent'to infrared. That's partly why I like SFX200. I sometimes shoot with a Horizont swing-lens panoramic. Film loading is a bitch, and hard enough when you can see what you're doing. Kodak HIE needed loading in darkness- SFX is loadable (?) in daylight and with the Horizont just makes life so much easier.
