E-Journal Photo Rez

[TomDeVrie@xxxxxxx]

One of the limitations for electronic journals in paleontology is the
resolution of scanners for photographic plates.  I have yet to see an
electronic graphic with the clarity and resolution of a darkroom-produced,
traditionally-published figure in JP.

How much resolution is necessary to produce a photo that is (a) adequate or
(b) excellent for electronic dissemination?  300dpi? 600 dpi? 1200dpi? More?

At the other end, what kind of screen or printing resolution do we need for
using the electronic photo?  The 72dpi on my Mac screen?  Do I need to invest
in a Tectronix high-res monitor?  What about the printer?  300dpi? 600?  How
many levels of gray?  Color?

These technological considerations would affect my decision to submit and
subscribe to an electronic journal.
