>Hasselblad used to sell a copying devise designed to make the film >plane and the subject plane precisely parallel. It was done with two >mirrors. One was placed at the center of the item you were copying and >the other was mounted on a lens flange in place of a lens and had a >hole in its center. The 1966 Hasselblad catalog has a picture of the >unit with the following description: >#40185 Linear Mirror Unit. "The Hasselblad linear mirror unit is used >in photo-copying when extremely accurate parallel alignment between >film plane and subject is essential. Using the linear mirror unit, >parallelism can be adjusted to closer than two minutes of arc. The >linear mirror unit consists of a lens flange mirror 40193 attached in >place of the lens on the Hasselblad 500C body and a reflecting mirror >40207 placed on the subject plane." that is a very good tip...and a fellow club member is a glass pro...that means experimentation! and generally i like playing around with gadgets... have saved your message for future reference, thanks... kostas ============================================================ so... no matter what, CHEER UP MY FRIENDS!
