I would like to experiment with IR film and have been thinking of getting some Rollei IR400. I have an Arca-Swiss F line basic. I am wondering what things I should be aware of when using IR films.

I have read some of the threads about bellows issues and that one should conduct a test to make sure their bellows is IR tight. Besides the need for a Hoya R72 filter (for the Rollei stuff), are there any other things I should be aware of? For example, does the shot process differ at all?

Thanks in advance.
