I'm intrigued, then, as to how the 'false-colour' IR photos I've seen are produced in-camera as I understood them to be?
Kodak Ektachrome IR Film would do it, but I'm not sure it's still available. It was E-4 process, which is way out of date now.

Very good Nigel, your exploration of the darker depths has paid off!

Usually we tend to see black and white IR shots. They can look very pleasing and have lots of impact and drama.

False colour IR photography is, I think, more difficult to do well. There are not as many subjects that are enhanced by it. On film, it's usually done without a filter for strange effects. This can be emulated in Photoshop by altering colour mixes. Anything is possible, but I suspect the novelty soon wears off.

The IR filters will just give you a red image. Some cameras are also more sensitive to IR than others, so the *istDS for example is quite nice for the best effects.

I usually stick to Photoshop for pseudo-IR effects. Other than that, it's down to having a go and seeing what comes out of it.

Sadly, fame eludes me and it is not me.

There are no electronic contacts on the M series lenses, and no "A" on the aperture ring. This means they cannot do some programs such as Tv and will only work in M and Av modes. Stop down will also have to be manually set.

The A series will work with almost everything, apart from not being autofocus of course. Just set the aperture ring to "A" and let the camera control things.

I'll make this a Sticky, for a while at least, to give those interested a chance to have a look at an interesting and useful idea.
