Subject: [filmscanners] PNG File format?



Hi all,

Just looking at file formats for archiving images. I've been told that
PNG is a lossless format that supports 24-bit (or higher) colour, and
has a compression ratio similar to Jpeg? Is this true? Is there any
sensible reason why I shouldn't archive my scans in this format rather
than JPEG? (I don't archive raw scans as they simply take up too much
space - I've got over 3,000 images to store).

Thanks

Mark
