Welcome to photo-3d, John.  WE do sometimes omit some topics, but 
when one comes that sparks interest,... do we ever get into it!  ;)

You have already turned up a few stones.  

Digital is a new thing for a lot of us, and it is costly.  

Giving consideration to the optimum method for obtaining, processing, 
and sharing images, my decision was to invest in the combination of 
Realist produced transparencies, and a high quality digital camera.  
Now, both cameras go on expeditions with me.

The slide copy adapter for the Nikon 990 camera just arrived 
yesterday. Teaching, e-mail and family obligations have kept me from 
experimenting beyond opening the box, but what I see looks inviting.  

The adapter will receive the RBT mounted slides readily from either 
direction side-to-side, therefore the Realist images can be mounted 
before copying. 

The light screen and holder rotates and locks in place, to bring the 
image into the horizontal position, but it is necessary to devise a 
track to elevate the image to the center of the shooting area.  I 
also plan to use one additional black half of an RBT mount to give 
more pressure, when holding the slide in the adapter.

Daylight, or artificial illumination can be used, therefore some 
effects can be produced by shifting the light source around.

A dual slide holder is included.  This will work well for those who 
use twinned film camera rigs.

And... a film holder for uncut strips is included. If we could only 
get them to make one with adjustable openings, it would be really 
handy for all of the typical 35mm films used in stereo photography. I 
will probably remove the vertical partitioning bars, then use the RBT 
slide as a mask for copying the uncut film.

I have been using the Bogen slide bar on a tripod, or "cha-cha" shots 
for making digital 3d images, but the thought of twinning did occur 
to me in one of my "less fiscally responsible" moments.  Thank 
goodness that I do not often act upon those ideas!

I did, however, think about the use of the remote control, that can 
be obtained from Nikon for my camera, I called Nikon technical 
services to find out whether or not it would be possible to get one 
remote control to operate two of the cameras at once... This would be 
the equivalent of producing an instant RBT type rig at about the same 
cost as a film RBT camera... Sorry about that thought, Jon Golden, 
but say maybe you will want to get that corner of the market. I am 
retired :)

I pointed out the obvious for Nikon... two cameras would have to be 
purchased, instead of one, and there would be an additional revenue 
from the specialized remote. (One that would operate the camera 
settings and the capture time of both cameras in tandem.) 

At least, the suggestion was considered to be of some merit.

Others may re-issue comments on the hacking of other cameras to get 
them to work together on the twinning rig, but my knowledge and skill 
at fiddling with electronic devices is limited to finding out how to 
work the things as they come from the package.  That can be difficult 
enough.  

Once again, welcome and have a good time. Do you know Dick Wood of 
the Alaskan Heritage Bookshop in Jeneau? Who else in Juneau do you 
know who is interested in stereo photography?   Thank goodness for 
the Internet.
