fstop, what effect do CPF's have on IR light? could do a couple of similar shots like the way you've done them with the ND?

While I don't know the maths. The CPF will have an effect on the exposure. Its not massive. but as you can see its helped with the sky in this example.

I'll do the test a little later but I would say probably but not as effective.

Does anyone know if the Canon 450D is any good for IR work? I'm coming to the conclusion that on Sunday I'll be getting a decent tripod and thinking about an IR filter as well but only if i can get some feedback on the suitability of my camera. :confused:

I'm interested in this as well (I have a 400D but imagine it will be similar)
