You now know how to make black and white and standard false-colour infrared images using your digital still camera. Now's the time to really experiment. Sure, film manufacturers have only made B&W IR film, or colour IR film with IR represented by red, red by green, and green by blue. You now have more control than that. The this page and the next show what happens if you combine the IR and non-IR images in other ways...
For
instance, you might just swap the IR+red channel from the IR image for the red
channel of the standard image, giving a false-colour image with sensitivity
extended into the IR, but perhaps a small dropout in the short-wavelength red
region. Most colours will look perfectly normal, but IR-reflecting objects will
be red.
Or
you might substitute the IR red channel from the IR image for the green channel
in the standard colour image. After all, in landscape photos, anyway, most of
the objects that reflect lots of IR are normally green in colour. I rather like
this one.
Or,
perhaps, you might try substituting the IR red channel for the blue channel
of the standard image. Not very natural, but a potentially interesting effect.
