Small Format Aerial Photography

A geologist may produce for himself a surprisingly accurate photo base map and stereo coverage at low cost without the use of expensive equipment and complex photogrammetry. If care is taken and the program well thought out, good results can be expected. The only equipment necessary in this method is a small format (small negative size) camera, a few rolls of film and the appropriate filters. A light aircraft, with an opening in the bottom, is preferable so that the pictures can be taken vertically and from inside - the aircraft. The method will produce high resolution prints at large scales in the range of 1: 1200 to 1:7200.
