Movie cameras either have moving registration pins that insert into the film moving along a fixed path (the Mitchell movement), or fixed registration pins and a movement that lifts the film away from the pins, moves it, and presses it back onto the pins (the Bell and Howell movement). Adding a moving registration pin to a still camera would be a major piece of engineering, made worse on the Hasselblad because it wasn't built to use sprocketed film in the first place. Adding a B&H-type movement would probably require replacing much of the film path no matter what you started with. Do you know anything about how the Nikon was modified? Anyway, my original comments were about a stock Hasselblad, not what you might be able to do by modifying it. (I've deleted net.columbia from the newsgroup list, since this no longer seems relevant to the shuttle.) Dave Martindale

As a matter of fact I do. Precise film registration is also required for some multi-image slide shows (i.e. projecting slides where the images from multiple projectors must overlap exactly), and for other applications. The following info is from "Nikon World", Vol. 14, No. 1, June 1981. Please note that I have no connection with any of the companies mentioned, and have never used the described products. * Two Firms Offer Pin-Registered Nikons * * It is widely known that Nikon is a favorite camera for photojounalists, * deep-sea divers, and astronauts. But did you know that Nikon is the 35mm of * choice for graphic artists, map makers, and animators? * It's true, and two companies, Oxberry Inc and Maximilian Kerr Assoc., * are marketing specially modified pin-registered Nikon systems that meet the * demands of the most discriminating multi-image photographer. * Oxberry's "Pro Copy Camera System" features a modified Nikon F2 camera * body, with MD-3 motor drive, electronic pin-registered camera back, AC/DC * power supply, 55mm Micro-Nikkor lens, and field guide. Oxberry claims to * make 14 modifications to the Nikon F2 body resulting in a Pro Copy Camera * "which will always advance to the correct position and stay in register * exposure after exposure, even when you wind back and advance through a * second, third, or tenth series." * The big news about Maximillian Kerr's "Pin Registered SS-F3 Camera * System" is a new 3-pin configuration. Kerr claims an accuracy of * +- 0.0001 "with moveable pins and pin-registration as close as 0.093" * from optical center. Other SS-F3 features include an improved Slide-magic * Optical Grid (focusing screen), fast film rollback, forward and backwinding * film counter, and provisions for Rotoscope Projection. * For more information on these two pin-registration systems, write: * * Maximilian Kerr Associates Inc * 2040 State Highway 35 * Wall, N.J. 07719 * or * * Oxberry * Division of Richmark Camera Service * 180 Broad Street * Carlstadt, N.J. 07072 * * (Nikon makes a disclaimer stating that the specs are that of the companies * and that Nikon has nothing to do with these people) While this info is over five years old (amazingly I remembered where it was 8-) ), I recall seeing other info about pin-registered systems for multi-image shows within the last year, but unfortunately cannot find the source. As I recall, the system (using an F3) was very, very expensive. Doug Wong
