In Reply to: Which film for helicopter pictures? posted by Ryan on February 12, 2002 at 15:25:16:
Most helicopter manufacturers make film that is suited to their particular models. Textron, which makes Bell helicopters has several types from asa 400 to 1600. They are treated with special 'active' dyes that harmonize with the frequency and rotation direction of the rotors. A word of caution though is that they are not to be used less than 100 feet above the ground because the synchronisation of the elastomeric bearings can nullify the vibration reduction benefits of this special film.
If you can't get this film then I recommend any film that will allow you to shoot at a minimum speed of 1/125 sec. otherwise the vibration of the helicopter may cause loss of sharpness.
