HOW TO HANDLE FEELING RUN DOWN:

This is a flash bracket/battery holder for a Nimslo.  It replaces the three tiny button batteries with 3 AA batteries.

It also allows for a remote flash location to eliminate "red eye".  You would need additional hot shoe to PC cord adapters of course.

MATERIAL: Wood; AA battery holder (a four holder, but one space will have a jumper wire installed since you only want 3 batteries); snap clip for the wire connection; pen spring; tripod screw; crimp on wire connector.

SKILL LEVEL: Easy.

RISK: Low.  You aren't going to lose anything but the cost of parts.

RESULTS: Very good unit.  It works great. I  also use it to carry to shows when buying Nimslo's.  It allows for quick checks of the camera.


The wires run down a slot routed in the wood.  The negative wire goes to a crimp on eyelet that is around the tripod screw, and when tightened it contacts the metal camera body.   The positive wire goes into the round dowel and is soldered to the pen spring that is placed inside of a drilled hole.  The spring contacts the metal battery compartment tab in the camera at the bottom.  The AA battery holder is a 4 place holder, but you only want 3 batteries for the right voltage.  You place a jumper wire or metal plate in place of one battery.


 


THE "TWINGE" BRACKET

It's a horizontal bracket.

It's broken?

It's a vertical bracket.

 

It's whatever you want it to be in 1 second.

The stereo twin hinge (twinge) bracket is the most versatile twin bar around.  You can switch from hyper horizontal to normal vertical lens spacings in only 1 second.  

It works great for slides and prints.

MATERIAL: Two flash brackets @ $12 ea. (with or without handles, or one of each); 1" wide hardware hinge.

SKILL LEVEL: Easy.  You just have to attach the hinge precisely, otherwise the cameras will be tilted or pigeon toed.  The hinge will need modification by removing the sloppy pin and replacing it with a 1/8" spring pin.  Oil the pin and work it in.  This bracket will not work well with a sloppy hinge!  The two camera screws will be common 1/4-20 pan head screws with the heads ground down in height to allow the brackets to close onto each other.

RISK:  Low. (except for the cost of two cameras) 

RESULTS: Excellent.  This is the only twin bracket I will use.  There are no compromises with this design.  The handle makes carrying it around very comfortable.   It can be attached to a tripod easily in either horiz. or vert. configurations.

NEXT TIME: I wouldn't change a thing.  


SON OF TWINGE

Want a smaller, full frame, twin hinged bracket?  With flash?  Auto focus? Zoom lens?

Here we are again.  

 

Note that the flashes are positioned next to each other at the center.  This is why the bracket is hinged like it is.  With both flashes inward there is less discrepant shadowing between the two images.

You can use the previous bracket design too with these cameras. It would be an easier bracket to make than this one, but the flashes will be outboard, and could produce more pronounced differential shadowing.

MATERIALS: Wood; momentary pushbutton switch; two germanium diodes to isolate the cameras; light duty hinge (not sloppy). Cameras are Ricoh with the elect. remote socket.

SKILL LEVEL: Medium.  This one takes careful dimensioning specific to your cameras. Usually takes some trial and error fitting to get the spacing correct.

RISK:  Moderate.  Since you need to buy two identical cameras , you will be risking their cost.  This can be expensive.  Of course you can use cheap 35mm cameras too.

RESULTS: Very good.  I love this setup.  It is so easy to take pictures with this that you are in danger of using too much film too fast!  I have taken both slides and prints, and the results are great.  The only occasional problem is the autofocus happening at slightly different times, producing an unsynch'd condition.  This is the difficulty of autofocus, the two cameras may focus on different objects because of the offset distance.  I don't think autofocus is necessary with twinned stereo photography, a pan focus or manual focus lens is better.  If one was building a one piece stereo camera, linking the two lenses to one autofocus mechanism would work.
