Sorry for responding so late. When I created that category my intention was to gather photographs from vertical cameras used in surveying, mainly for photogrammetry, like the Wild RC8. Those photographs show the features used in en:photogrammetry, such as time stamp, calibration marks, calibrated camera constant and other things that could come in handy in more detailed wikipedia articles about photogrammetry, and also of course wikibooks touching that subject.
