I have little experience with Polaroid since the '60's when I occasonally
used a Polaroid back for my 4x5 (9x12 cm) Linhof. Since then I've only used
Polaroid for 'scope pictures.

However, what I do recall is that while they're OK for use as full-scale
snapshots, the film is too grainy for enlargement. I learned about this
when I used the negative film from Polaroid. I've concluded that the
quality of the photos from this technology is not as high as what's wanted
by users of digital photography in general, i.e. I doubt it's up to the
quality of the 640x480 resolution of the Sony cameras.

My interest in digital photography has been stimulated by the need to
integrate photographs into technical documents and correspondence. There's
plenty of software for rendering the color photos as what they are, up to
"glossy-paper-magazine" e.g. Time or Spiegel but once you start to enlarge
the image, the lack of resolution becomes a major factor. I've considered
other image processing approaches, e.g. scan-rate conversion software which
reduces a raster image to Fourier series in both directions, thereby
allowing you to "fit" the image to whatever resolution you like, though it
requires post-processing to straighten and sharpen edges, etc.
What really puzzles me is whether it can process and render a photo as black
and white line-art. Anyone have
experience with this?
