After seeing the announcements of the new Burder repro of the Realist
Macrostereo camera, I knew I wanted one. Unfortunately on a retirement income,
I didn't have $3k to spend. I'm definitely not in Burder's league when it
comes to camera construction-- his cameras are works of art-- nor in the
league of people like De Wijs, who is probably the best builder of stereo gear
in the world. So a few friends gave me some tips, reviewed the math for
aperture and lens placement, and supplied camera parts out of their junk
drawers. My tools are comprised of a cheapo Chinese drill press, a Dremel
tool, hand files, screwdrivers, and the usual odds and ends, plus basic
measuring tools. The camera in the photo is the result. A wire framing box
will be attached later-- I don't much like the prong system for composing-- I
need to find just the right coat hanger to bend... It was built in about a
week on the kitchen table, much to my wife's dismay. The body is a Realist--
the model with the double exposure release-- and the lenses are from a Nimslo
(moved out from the film plane 10mm beyond the intended 30mm fl). It uses a
Prontor type shutter from a Polaroid copy stand, many will work if the center
opening is big enough. If it's a shutter with aperture adjustment, just
superglue the aperture at full open. The front plate was made from a piece of
scrap 1/8 inch aluminum that cost a dollar at the local sheet metal shop. The
camera back was opened up with a metal file and a septum added. (the little
sprocket gear needed one side shaved off a little). I made a few blunders, but
overall, the construction is pretty simple. Construction time, not counting my
errors, is about 25 hours. This Hackro Macro cost about $40, plus a little
help from my friends. So if you don't have big bucks and want a macro, don't
be dismayed. If you can handle basic tools like a file and a drill, you can
just build one. I'm pulling together a photo compilation of the construction
that I'll forward to Sam's camera hacker site in the next month or so. Also,
the photo that was taken with the camera is a Lara Crofts 6" tall "Tomb
Raiders" action figure, photographed from a distance of 5.5 inches, and with
the flash angled from the left(cross eyed stereo viewing). Note that this
image is much lower quality than the razor sharp original-- I scanned a slide
at 1000 dpi and further reduced the image quality for Internet use. It was
just field tested yesterday-- all the film advance was perfectly even, as were
the exposures.
I think you could make this rig with any junk stereo camera with a good
advance mechanism and a lot of room inside-- the camera I used had no lenses
or shutters, but you throw all that away in any case, as well as the shutter
trip mechanism.
So haul out the hacksaw and have some fun!
