I scan at 3600 dpi and 16 bit, clean up dust and scratches then save as a TIFF. From there I do whatever modifications seem appropriate and save that as a different file in TIFF mode. When I get 20 or 30 gigabytes I burn some DVD's then clean the hard drive. Remember, I always have the original negative or slide as the ultimate backup. Currently, I am moving my collection of CD's to DVD's. I expect that when the Blue Ray standard stabilizes I will migrate to that. Archiving for me is pretty simple, I have proof sheets of all the discs and proof sheets attached to the discs filed by date and or subject. For those of you in the entirely digital world, I would probably do the external hard drive routine as well using a data base program to find images. Remember the mantra, storage is cheap, redundant copies are a good strategy, storage in conditions you find comfortable but a lot dimmer is also a good thing. Enjoy the process.

I have the same problem with tiff files of large hi res scans. A 4000 DPI scan saved as a 14 bit (Nikon V) Grayscale TIFF is something like 41MB per frame. A roll of film is over 1GB and won't even archive to a CD, perhaps a more serious issue for me than HD space (although, that too quickly becomes an issue). Different applications have different problems with TIFF lossless compression schemes (zip, lzw), so that doesn't present itself as a viable option. What's worse, though, is that JPEG is 8 bit, so I loose alot of information before even JPEG compression kicks in. The whole thing is odd to me, I recall the days of PCX, and we've come a long way since then. But why isnt' there a universally supported lossless compressed format that supports 16 bit gs and 48 bit color? Really wierd to me. What do other folks do to archive hi rez scans of rolls of film?
