11x14 Fidelity Medical Cassette (11x14 Fidelity Film Holder)

Recently I looked to buy some NEW 11x14 film holders for my Deardorff and Seneca 11x14 view cameras. New 11x14 holders are very expensive and hard to find because no manufacturer makes them anymore. After extensive searches and long waits I was lucky that I found some new old stock of 11x14 Fidelity Medical Cassettes which are exactly the same as the regular 11x14 Fidelity film holders after the bars/ears that were modified for X-ray machine are removed from the cassette. The holders were well made in USA. Dark slides and septa are real metal sheets (not plastic) and unbreakable.

Restoration of an Ultra Large Format 11x14 Improved Seneca View Camera


Part I: The original camera


I bought this camera and wanted to restore it. The camera frame looks good, but the bellows is bad and several knobs are missing, no rear extension rail.

This camera is about 100 years old and was made in Rochester, New York, USA. It weighs only 12 ½ lbs without the extension rail and constructed of mahogany/cherry with polished brass hardware. Focusing is accomplished via front and back rack and pinion movements. This camera has rising and falling in the front standard, swing and tilt in the rear standard.


Part II: Camera was cleaned and the bellows was removed

Camera without bellows

Bellow frames



Part III: Make a 11x14 bellows

Fabric: 2 layer Gore Tex nylon

Craft bond glue and poster board 

Pleat design for bellows


Pleat printouts


Pleats are made from poster cardboard and are ready to be glued on to fabric


Folded bellows

Part IV: After installation of bellows
