Hi,

Margie Purser and I are putting together a poster session for the SHA 
meetings in Sacramento: "The Principle Then and Now: An Update on 'Photography for 
Discovery and Scale.'"

Margie's abstract reads as follows:

"In 1988 Gene Prince of the Phoebe Hearst Museum of Anthropology published a 
short note in Antiquity entitled 'Photography for discovery and scale by 
superimposing old photographs on the present-day scene.' The technique he'd 
developed was simple, relatively low-tech and low cost, and leant itself to a myriad 
of applications. Dubbed 'Prince's Principle' by Ivor Noel Hume, the technique 
has had a fascinating if not highly publicized career. In the intervening 
years, it has been used for purposes of site location, architectural 
reconstruction, and public interpretation. Experiments have extended the application from 
historical photographs to paintings and lithographs, and have reproduced the 
technique digitally for website applications. This poster session showcases a 
sampling of the Principle's case studies, both to increase awareness of this 
amazingly useful technique, and to provide a forum for sharing innovations for 
using it in a range of different physical and technological contexts."

We would like to hear from people who have used the photographic method for 
discovery and interpretation, successfully or not, since I gave a paper on it 
at the SHA meetings in 1986, or from its original publication as noted above.

Probably better to reply to me off list.


Best,

Eugene (Gene) Prince
