And as non PC as it is, I don't believe in archival digital images anyway.
Just because we can capture huge images, should we? Digitize for Access, yes
and mass distribution, but not for preservation, except as it reduces
handling of the original. The right resolution for proper access
In terms of original digital capture, not surrogate conversion, I think we
must look at it as we did (do) film; different formats ( slides,
transparencies etc) for different purposes. What you need to define is:
The access you want to achieve.
The level of detail that your originals warrant.

Thank you to all who responded to my query. Your questions and
responses have in turn challenged my thinking about the original
problem. While the functional master will need to be quite large to
meet many potential uses, I wonder if we need an archival master of a
surrogate of a surrogate of a

It details all the theory behind scanning, not only what can be done - but what a scanner cannot do. You may also want to look into software that gives you the flexibility to do what you need. We use a program called VueScan
The bigger the file size (70MB - 250MB is not uncommon) the better. In
other words, the bigger the file the more information on the object is
captured. Also, focus on one master format, i.e. TIFF is a very common
format in this regard (do not compress the files) and if you apply color
As I said, surrogates, not masters. Masters are un-cropped, first
acquired digital images. Any corrections to the original digital image
makes it a surrogate.
Color corrections are necessary once you start making reproductions of
the masters for print or online display. Those copies of the
I second this. Don't get in the habit of keeping layered Tiffs around
beyond the image processing / pre press stage.

Simple. Memory and budgetary limitations.

You might also want to make sure that your camera / scanner can
deliver 4000 DPI; otherwise your making a lot of pixels. There are some
benchmarking techniques available to ensure your device can produce the
resolution you expect.
