Working Group 3 Organization and Individual Studies of Workers: 
The group is composed of scientists and engineers who have recognized and in- 
vestigated imagery and the effects of the environment on photographic sensor 
systems. Their individual studies, referenced to Working Graup 3 are briefly 
discussed. 
Clarice L. Norton is chairman of the W.G. 3. For the last three decades she 
has been concerned with the capabilities and qualitites of aerial reconnaissance 
and mapping cameras serving as the Director of the Fairchild Camera Calibration 
Laboratory and Chief of the Optical and Photographic Quality Section until 
1968. Since 1970 she has directed the technical activities of the Camera 
Calibration facility at Hill Air Force Base in Utah, and provided technical 
consultation on photographic sensors. She has been involved with image quality 
and geometry investigating their properties under laboratory, flight, and 
simulated environments, writing papers and serving as chairman on image quality 
panels of professional societies. 
Norton was Secretary of Commission I from 1968 to 1972 and chairman of the 
OTF/MTF working group from 1972 to 1976. She has been Director of the Photo- 
graphy Division, Chairman of the Color Committee, and Chairman of the Image 
Quality Committee in the American Society of Photogrammetry. She is presently 
Chairman of the Sentinel Sigma Image Quality Committee, which is investigating 
and rewriting U.S. Air Force standards on photographic systems. She has con- 
tributed to ASP III Manual of Photogrammetry and Aerial Color Manual. Norton 
has a B.A. from New York University and has pursued advanced courses in photo- 
grammetry. She is a member of ASP, OSA, and SPIE. She is listed in Who's 
Who of American Women, the World's Who's Who of Women, Who's Who in Engineering, 
and others. She received the ASP Photogrammetric Award in 1964. In her WG-3 
study Mrs Norton has drafted a questionnaire on the conditions of pressure 
and temperature to which cameras are subjected during surveys. The answers, 
received from seventeen countries, are analyzed in a following section. Plans 
are made for a simulated laboratory study. 
Philip Douglas Carman is conducting the vibration studies reported by this 
  
working group. His studies on vibration started during the second World War 
and about five years ago renewed interest was generated. Important results 
of flight and laboratory tests were subsequently published. 
Carman earned his BA at the University of Toronto and his MSc at the University 
of Rochester. He is presently Senior Research Officer at the Canadian National 
Research Council directing the activities of the Camera Calibration Operation. 
Associated with NRC since 1941 he has been involved with testing, design of 
photographic equipment, photogrammetry, and research on optical and photo- 
graphic instruments. Optical and photographic image quality has been a pri- 
mary concern, as attested by his various papers and membership on national 
and international standards committees. He has served Commission I in many 
capacities, as Secretary, as correspondent for several quadrenniums, in many 
committees. He was largely responsible for collating the Commission I standard 
"Procedures for Calibrating Photogrammetric Cameras and Related Optical Tests".
