Dolores Archaeological Program Technical Reports, DAP-071: Photography - 1980

Author(s): Michael J. Hilton

Year: 1983

Summary

This report describes the activities of the Dolores Archaeological Program Photography Group during the 1980 analysis year (1 May 1980 through 30 April 1981) and documents changes in the photography system that occurred during that period. A total of 889 person-days was expended during the reporting period by the Photography Group. A total of 225 rolls of film were exposed on fieldwork subjects, and 193 rolls of film were exposed in the production of laboratory photographs. A new graphic catalog form, one which made possible more accurate recording of photographic data, was instituted. More emphasis than in previous years was placed on bipod photography. A new camera mounting system was employed on the bipod, and ground control point placement was more rigorous than in the past. Eight additional film lines were calibrated and new equipment was acquired for the production of chips. Topical packages were prepared during the reporting period--22 containing photographs of single sites, and 5 containing photographs of particular topics, which include photographs from all applicable sites. The review of computer codes describing photographs was shifted from the data coordinator to the Photography Group. Photometric research continued in 1980 and included both the production of photomosaics and photogrammetry. Included is a discussion of the comparative costs of the two processes.
