TDC History

Here is a very nice german site detailing the history of the Bodensee factory that assembled the Stereo Colorist I and II. If you don't read German, just use Google translator. Colorist I development began in 1952 and Colorist II development in 1954. Between May 1954 and June 1956 the Bodensee works provided approximately 20,000 stereo cameras to Cinefot, who supplied these cameras to Bell & Howell aka Three Dimension Corporation (TDC). 13,000 were Colorist I's and the remaining 7,000 Colorist II's. There was originally planned to be a Colorist III in two versions (right) but stereo photography didn't exactly take off in America- the new trend was color photography- and Bell & Howell got out of the stereo market. By 1960, remaining Colorist I's were being sold for as little as $19.95

One innovation of the Colorist was its use of a machined aluminum top plate instead of chromed stamped brass. At one point the Bodensee factory tried to sell the Colorist to the German public as the Bodan Stereo, but Cinefot put a quick stop to this as the cameras were to be built exclusively for them.

The Colorist I and II are basically the same. The II added a coupled rangefinder. The II's original list price was $125 but had dropped to $79.50 by 1958.

Cooke Triplet


The lenses on the Stereo Colorist are f/3.5 Cooke Triplets. These are 3 element in 3 group lenses. Here is a link to some information from Cooke Optics. Crown glass is in blue, flint glass is in green. The Cooke Triplets were used on these Realist format cameras...

A Nice Stereo Site

http://www.stereoeye.jp/index_e.html I learned how to view stereos cross-eyed!

Kodak


Kodak may get rid of its film business...
Here's the story

B&W Slides

My decision to finally get a stereo camera was brought on by several factors...



  • We now have two incomes so we a can afford a few luxuries.
  • My father-in-law is into stereo photography and has a Realist and a projector
  • I discovered it's possible to make B&W slides with TMax 100 Film and the Kodak Direct Positive film developing kit. Reversal processing is a lot like processing motion picture film. Note: this kit cannot be shipped via standard shipping. You can't mail order it from B&H or buy it over Ebay. Call Kodak and they will tell you where the nearest photo shop is that can order it for you.
  • I already have a nice shoe-mounted light meter.

Stereo Colorist


My father-in-law has gotten me interested in stereo photography so I purchased my Stereo Colorist II off Ebay for $175. I can't wait for it to arrive. Differences between the Colorist and the Colorist II

  • Addition of a split-image rangefinder
  • Frame counter is slightly different
  • Slightly heavier (717g vs. 660g)

Nice features

  • Shutter cocks with film transport (unlike Realist)
  • Split-image rangefinder integrated with viewfinder (Revere/Wollensak and Realist have separate rangefinder window- who wants to look through two windows when you can do everything in one?)
  • Hotshoe compatible with electronic flash (TDC Vivid has a non-stanard flash terminal)

Owner's Manual link is here. Another link here.

A very nice document on the history of TDC and their stereo products is here. I was going to get a TDC Vivid, but I read about some flare issues here and image overlap problems here and the film transport seems unnecessarily complex.

I already own a Voigtlander VCII Meter which mounts right in the hotshoe so who needs the Vivid's Expo Sure calculator?
