This is an image taken and processed in 2003 :o
I was using the 10D then, and that camera is blind as a bat when it comes to IR, but I was determined to do it.
Got the Hoya R72 filter, a reasonably priced IR filter. Try to do this on day with no wind, because you'll have very long exposures.
Set your tripod up and the camera firmly attached.Preset your white balance to custom metering on green grass or foliage. No filter yet! Focus on your scene (f/11 or more) with as high an ISO as our camera can handle and get away with. Once you have obtained your focus, set the lens to manual focus. The filter is very dark and you will not be able to see anything, if you leave th AF on, it will hunt and not find anything. If it is on manual focus, it will keep your distances.
Attach the filter and take the picture as metered now (it may be a several seconds exp), using a cable release or the self timer to avoid moving the camera when pressing the shutter.
Your resulting image should have a reddish brown cast. If not, play with the white balance or set the white point in the vegetation.
Once converted, go to File>Image Adjustments>Channel Mixer
Choose the Red channel and adjust the slider to show 0 on the red. Go to the Blue channel and adjust the blue until 0 is on the blues. Leave the Green Channel alone. Now process your image to taste, curves, sharpening etc.
Playing further with the Channel mixer should give you different hues, as in the case here. Usually you'll get blue skies and white vegetationPlease, keep in mind this was done as a rookie ;)
