WG-3 Questionnaire 
  
The Working Group 3 of Commission I is concerned with the variables of image 
properties due to environments which differ from controlled laboratory 
conditions under which cameras are calibrated. A questionnaire was developed 
to determine the actual environments of temperature and pressure which existed 
when photography was acquired. The questionnaire heading also requested in- 
formation on preflight environments. The paragraphs which follow quote the 
question, summarize the answers, and make limited analyses.
