Tom, Surely the whole purpose of collimated light sources is to achieve maximum resolution (I seem to remember this from my light microscopy days many years ago). If you use diffuse light, you will not achieve max resolution: it's equivalent to blurring the image. The Minolta 5400 has a removable diffuse light filter, and if you switch it into position, you lose resolution, and the image becomes soft. You also lose resolution on the dust and scratches, but you can't have one without the other (as Doris Day used to sing).
Bob Frost. ----- Original Message ----- From: "HPA" <[EMAIL PROTECTED]> DIFFUSION OF LIGHT SOURCE: The Polaroid uses diffuse light, which minimizes dust and scratch marks on the base side of the film. The Nikon uses collimated light and this accentuates dust on the base side. Of course the Nikon has the automatic dust removal, however that does not work with Kodachrome because the film is opaque to IR light. ---------------------------------------------------------------------------------------- Unsubscribe by mail to [EMAIL PROTECTED], with 'unsubscribe filmscanners' or 'unsubscribe filmscanners_digest' (as appropriate) in the message title or body
