filmscanners: Infrared scan

[Rob Geraghty]

I just tried scanning a slide and outputting a colour TIFF and an IR one.
It was very educational.  Any sort of mark, scratch or dust spot is utterly
black in the IR scan.  Some of the image is also visible as is some of the
grain, which probably explains why the image is softened by ICE.

I haven't tried a non-chromogenic film yet, or kodachrome.
