DIMi is running an infrared photography competition sponsored by
MaxMax.com with monthly IR filter prizes and a grand
prize of a digital camera conversion to IR mode, worth US$450.

Erm, presumably you need an IR camera in order to take part in the
competition, and so the grand prize would, kind of by definition, be
worthless to its winner?

Not necessarily so. Many digital cameras can take IR pictures using the
relevant filters.

That is not IR Photography. There is a big difference between using a
filter and using the film.

True, especially if you're thinking of Kodak IR film. With digital, if
you want halation and massive grain, you need to add it in processing.

Not a slam of HIE, I actually do like its halation and grain. But if
you have a good digital IR image, you really can add the halation and
grain afterwards.

As far as sensitivity to IR, digital cameras that still have their
internal IR-blocking filters are slower than Konica 750 IR film with an
87-series filter. But if you have a camera without the internal IR
blocking filter, digital can be as fast as HIE, and most digital sensors
are sensitive much deeper into the IR spectrum than film IR was.
