right,
I've tried this and it worked okay
however, this weekend a snapping weekend away and it all went wrong

the centre of the picture over exposed, happened on my 50mm and my friends kit lens
i've managed to make it work before okay on the 28-105 canon
I have a 350D

is this the hot spotting!? or is my filter borked!?
could do with a filter for my 17-85mm and give it another whirl

Get your camera and tripod.
Set it up on a garden.
Composure your shot looking at some grass only.
Get the focus right etc etc.
Put the IR filter on
Take the shot.
Go into your camera menu and choose custom white balance.
Set it to the picture you last shot

Well you can shoot RAW and do the WB later but when you get chance I would still create a custom WB and then use that.

You need to use M mode. Manual.

Your exposures will not be metered in anyway so it will be up to you to decide just how much exposure the shot is going to need. Start off with

ISO200
F8
15 Seconds (long exposure noise reduction on)

If you really have no idea of what sort of exposure to use (which you won't at first) then an easy way to work is shooting at the highest ISO and widest aperture available.
Then use cunning maths to transpose your decided exposure to a lower ISO and stopped down aperture.
