first of all thanks to kort to advise me about this tread...
than excuse me for my english mistakes :(
my experience has start with an hoya r72... probably the well know infrared filter... it works at 720 nm... than i've tried a very cheap filter (10 dollars at ebay) that works at 900nm... the difference is really strong....
in the first case we may able to to capture part of visible light and the infrared light...
in the second case just infrared ... the result are strong contrast between the dark parts (for examples skies) and glowin' parts (foliage)... but due to the extremely long exposure (30" seconds... i've not yet a modified cam... hope it will come when the canon 40d will released)
and the monochrome result my choice was the hoya r72... i like false colours infrared a lot....
in this case the first rule is (as john said) to forgot auto white balance!
the best result is setting the white balance manually... if you've the possibility to save your photography in raw this process may be very fast!
in the past some people has ask me a lot about infrared... so i've written a first-steps tutorial on my site
you may see the difference of white balance choices!
the rest depends by your fantasy!
hope it helps!
