Digital imaging

In reply to Bas van Velzen's posting for his colleague: yes,
research has been done comparing digital and analog duplication of
negatives, as well as print materials. The people to contact on this
topic are Steven Puglia at the National Archives and Records
Administration in Washington, D.C., and James Reilly at the Image
Permanence Institute. Jim gave a presentation on this topic at both
the AIC's Photographic Materials Group 1995 Winter Meeting (held in
D.C.), and at the IS&T's (Society for Imaging Science and
Technology)'s 48th Annual Meeting. His presentation is included in
the final program and proceedings for that conference. Jim Reilly
can be contacted at:
