I processed (as in "evaluated") quite a few miles of that film as a Photo Interpreter in the Air Force, mid-late 1950s. Exceedingly sharp and detailed at lower altitudes when perfectly synched between air speed and film advance. "Bombing" practice runs were photographed on 9x9 masks, as well. The 9x18s were used in split verticals, so the center image formed in overlap was in stereo. Many happy hours spent with a forehead on the stereoscope over a light table, cranking and marking those big rolls of negative film, and a few of positives. I saw some really long-distance obliques made from a very high-flying airplane with an immense folded lens in its narrow body. Not very impressive in the sharp/detail sense. -- Frank ess |

Possibility the longest panoramic image was made this way, the film moved over a slit as the aircraft travelled over the country side. I think they ran out of film eventually. |

Shots he's taken with a digital camera of old newspaper and magazine ads and printed. I'm sure old aerial reconnaissance shots would be very interesting to print large. I worked for awhile for Kenting Earth Sciences, and we printed mural sized aerial abstracts as office decor. Landscape aerials always looked interesting. Now they could have an interesting decor market, but they have closed down. They were interesting to do, some landscapes on the 9" film looked like macro shots. I have some here on 9" film - at one stage was printing them up but then came along Google earth. |
