The Transparency Copy Holder; The Microscope Adapter; The Microscope Shutter; Miscellaneous Accessories - Hasselblad 500 C User Manual

The extension bellows can also be used for copying transparencies with
the aid of the transparency copy holder. This fits on the front of the
extension hood and takes transparencies (or negatives) which are
illuminated from behind by suitable light source.

The Transparency Copy Holder

This is an attachment which is used in conjunction with the extension bellows and hood. It permits copying of colour negatives and
transparencies. You can at the same time correct under-exposure, colour casts, too contrasty or flat colour transparencies. You can
also duplicate colour copies or black-and-white ones. Finally, you can use the copy-holder for making colour separation negatives.
To use the copy holder, push it into the grooves on the front of the hood of the assembled extension bellows unit. Attach the support
bracket to the bellows with its tripod screw. Release the ground glass screen by the catch on its base, insert the object to be copied
and tighten the locking screw above the catch. Focus and set the degree of enlargement. Tighten the support bracket screws and
expose.

The Microscope Adapter

This can be attached to the Hasselblad 500C to provide an effective, convenient connection between the camera and the microscope
eyepiece. The microscope adapter can be connected either directly to the camera-in which case the exposure is made with the rear
shutter in the camera body-or with the microscope shutter especially designed for photomicrography.

The Microscope Shutter

This is an XM-synchronized Synchro Compur shutter with speeds from 1 to 1/500 see. and B. It is tensioned and released
automatically and is used in conjunction with the microscope adapter. Use a cable release to avoid vibration. Alternatively, open the
rear shutter before the exposure, by pressing the quick-release button. The exposure will then be made by the micro-shutter alone on
pressing the release button on the camera.
If the extension bellows is fitted between the microscope shutter and the camera the magnification provided by the microscope lens
can be adjusted continuously.
The extension bellows, like the microscope adapter, provides a completely vibrationless microscope attachment. If the focusing hood is
used, the microscope image appears directly on the ground glass. The double cable release for the extension bellows then opens the
rear auxiliary shutter immediately before the between-the-lens shutter, and so ensures a vibration-free exposure.
A LENS MOUNT ADAPTER is available to connect special lenses such as generally used for photomicrography to the Hasselblad 500C
camera.
THE LINEAR MIRROR UNIT permits extremely accurate parallel alignment between film plane and subject in copying. It consists of a
lens flange mirror attached in place of the lens of the Hasselblad 500C and a reflecting mirror placed at the subject plane.
A RINGLIGHT can be attached to all Hasselblad 500C lenses, except the 500-mm. It gives even, shadowless illumination in close-up
work in research, medicine, technology, etc. It is fitted with cables to connect with Paffrath C Kemper electronic flash units.
