[AT] Digital Archiving

[Larry Goss]

Define "best."

For those who want no compression, true fidelity to the original image, and some other features, there is no substitute for TIFF.  But I'm more concerned about a virtual paper-trail.  As such, I can work in the header of JPEG (rather than the actual image database) and be perfectly content even though I know there are compromises being made behind the scenes.
