The simplest facts are often more interesting than creative knee-jerk cynicism and paranoia. When you constantly wade up to your armpits in bull**** it is difficult not to stain everything you post. Measure twice. Post once. The film used exactly the same plastic, coated with the exact same photo-chemicals and processing. Thinner emulsion only improves some of the details and it can otherwise increase the ASA/ISO speed of recording photons in low light conditions, and that didn't even measurable improve upon its dynamic range. Those NASA/Apollo missions didn't need or having demonstrated any of those benefits. The lens (all of them) was terrestrial standard optics with the exact same coatings. Your Semite run government lies to us so much of the time that you think everything is exactly as it should be, as long as the whole truth and nothing but the truth never gets out. http://groups.google.com/groups/search http://translate.google.com/# Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG / “Guth Usenet” |

The simplest facts are often more interesting than creative knee-jerk cynicism and paranoia. When you constantly wade up to your armpits in bull**** it is difficult not to stain everything you post. Measure twice. Post once. Kodak went along with them to the moon – in a couple of ways. We provided three different types of film: Ektachrome EF film SO168 Ektachrome MS film SO368 35mm film used in the stereo Panatomic-X recording film – this was specially developed for use on the moon - http://www.kodak.com/eknec/documents...8fe/ti2344.pdf STORAGE For consistent results, all aerial films should be stored under fairly constant conditions. Kodak aerial films are “usually” packaged in equilibrium with 40 to 50 percent relative humidity. High temperatures or high humidity may produce undesirable changes in the film. Unexposed Film Store unexposed film in a refrigerator at 13°C (55°F) or lower, or freezer at -18 to -23°C (0 to -10°F), in the original sealed container. If the film is stored in a refrigerator, remove it about 2 hours before opening; if stored in a freezer, remove it about 8 hours before opening. A sufficient warm-up time is necessary to prevent moisture condensation on cold film— otherwise, moisture spotting, ferrotyping, or sticking may occur. Exposed Film Keep exposed film cool and dry. Process the film as soon as possible after exposure to avoid undesirable changes in the latent image. If it is necessary to hold exposed but unprocessed film for several days (such as over a weekend), it should be resealed and refrigerated at 4°C (40°F) or lower. Before unsealing and processing exposed film that has been held in cold storage, follow the warm-up procedures. - They didn't use this type of thin film, because the film they used was wide thermal tolerant and rad-hard, as well as their color film was impervious to temperature extremes, radiation and automatically filtered out all weird and natural colors. Even pictures of Earth were pastel and/or way underexposed. http://groups.google.com/groups/search http://translate.google.com/# Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG / “Guth Usenet” |
