Oh, by the way. Our plan here for our collection photography
is to store the raw file, create a master tif file (that has been
corrected for dust, color, etc.) and from that make various jpg
derivitives (as needed). However, do to storage space limitations, we
are considering using a new system that uses an application
to generate derivatives on "the fly" to be delivered to our users.
Saving the cost of storing each derivative file.
We also keep each file seperated in a folder for that file type, raw,
tif, jpg_screen, jpg_thumb.

There's probably no perfect way to store images on
a filesystem, so maybe it should just come down to personal preference. Unless
you need specific security settings--for example, so some people can see/edit
some files but not others. In that case, you might want to build the
arrangement to mirror the security arrangement, which will make setup easier,
and corrections a lot easier. There might also be other factors like that,
that I'm not thinking of. Anyone else?
The "right" way to store images
is in some kind of databasing system that keeps image metadata alongside the
image files so that you can always find them again by working your way down a
hierarchical tree (bad but demonstrative example: Paintings--19th
Century--Impressionism--American--Cassatt, Mary--The Cup of Tea) or by
searching according to subject, artist, media, title, etc. It's hard to
impossible to duplicate that with directories on disk and maintain it
reliably. These syst ems go all the way from $0 to high six figures in cash,
and take significant effort and time to implement and maintain.
good
luck,
Matt

Hi all:
I'm currently developing our digitization
procedures and I was wondering what other institutions do to organize their
content. I'm planning on photographing identification & database images
in a fairly high resolution jpg and photograph in RAW for
publication-quality. Once the images are downloaded, I'll be processing them
in small, medium and large dpi (72/150/?) and saving the original. What I'm
really sort of curious about is how many different file sizes people save in
and if they keep file directories for each size or lump them all
together.
Hope you're all having some relaxing
holidays!
