[photo-3d] Zeiss Contessa-Nettel 10x15 stereo camera

[Ralph Johnston/Linda Sherman <copley@xxxxxxxxxxxxxxx>]

I took this camera over to Henry Weisenburger yesterday and he showed me a
few things about it I didn't know.

The lens board has shift and tilt AND the left lens can be moved over
toward the center to reduce the stereo base for close ups.  The bellows is
double-extension, so you can get almost 1:1 images.  We focused on a
flashlight and measured the image in the ground glass.  There is another
scissors support inside the bellows to steady the lens board when extended.
 If you cap the other lens and remove the septum divider, then you can get
10x15cm "panoramic" images per McKeown.  I think the close-ups are a better
use for this feature.

The focal plane shutter works.  The small dial sets the tension to one of
three.  The large dial as three scales, corresponding to the 0, 1, or 2
tension settings.  Set it to "T" for ground glass focusing.

The ground glass slides out and can be replaced by either the film pack
holder, or one of three dual plate holders.  These have metal septums for
holding 4x5 cut film.  A stop has been added to keep the film located.
(You would lose almost 1" off one image I think)

The camera is a "Deckrullo-Nettel Stereo" 1919-1926 by Contessa, then
continued by Zeiss.  It was also made in 6x13cm and in teak.

It is about 2/3 of the way down.  I plan to split this page into two (or
three) soon to help out those w/o cable or DSL modems.
