[filmscanners] RE: Compression

["Paul D. DeRocco" <pderocco@ix.netcom.com>]

I've experimented with JPEG2000, and think it's much better than JPEG.
However, until my image cataloging software (ThumbsPlus) learns to read
JPEG2000 with 16 bits per channel (which is promised in the next version), I
haven't converted all my 16bpc TIFF files yet. I can hardly wait.

There's also Genuine Fractals .stn files. But I think of that more as a tool
for preserving edge detail while upsampling, and not a general purpose
storage format, since it is only processed by their proprietary software.

This only gets more important when you get a digital camera, and the cost of
taking pictures drops to zero. You get trigger happy, and your shelf fills
up with CDs pretty fast.
