HI All again after some research, I have managed to find out that the COKIN P007 (89B) IR filter is not too good with the 350D, but an up shot is the HOYA R72 works excellently. Heres a link for a website which gives most settings for cameras, the most usual for the 350d seems to be Avg Ev 1.6 EV 1.6 T 2.5 (this will be dependent) F 11 (so will this) ISO 1600(Alter as necessary) I would watch out for high noise at these levels, and the focus, but that should not be a major problem as long as you are careful, I think you might also get away with T 1 with a f8 and ISO 800/1600 BUT REMEMBER TO DECREASE the T anf the ISO levels. As with anything I would suggest a serious learning curve to get the best you want. I also recommend setting the camera to B&W and setting a White Balance using 18% GRAY CARD.

but there is a test image to look out to get the best out

Jessops Are doing the HOYA R72 58mm Diameter for 34.99, if you look around you may be able to pick one up, But the COKIN is Around 10 cheaper from JACOBS.

TIP

Remember to remove any other filters off the lens 1st, like polarisers and skylights/uv's.

Hope its of some help.
