My infra red experience with black and white film in the 1960s failed to impress me - wrong subjects, wrong expectations. I really enjoyed using Kodak IR Ektachrome and still have a couple of rolls. It does require E4 processing though and we're now on E6.
It did result in my trying again with one of the visually opaque IR filters on a Sony a7rii, and surprisingly (to me) if I set the highest possible ISO I could get an image with the lens wide open and a rather longer exposure than I care to hand hold. It confirmed that some cameras are able to just about manage an IR image without having the filter removed, so it's well worth a try to see how it goes.
I've seen a lot of stunning IR photos in black and white, and someday may get a camera converted. I'd like to try colour IR again, if only to test a theory that with two exposures made with and without a filter and using a tripod could be combined in Photoshop with channel changing and discarding the blue image.
IR Ektachrome was conceptually just like a normal RGB three colour emulsion, except that the colours were all shifted one place, dropping the B and inserting IR in the sensitivities but keeping the normal colours, so IR came out red etc..
Definitely worth giving it a go.
And as this will probably be my last post this year, a happy new year to everyone.
