With the reduced availability of color transparency film, I am wondering if there would be a market for tricolor stereo cameras. These use three rolls of black & white film, dichroic mirrors and/or half-mirror beamsplitter mirrors with filters. Black & white films have higher resolution and wider dynamic range than color stock, and the "color separation records" produced on them are as archival as other black & white stock. These could be made in any size for which black & white films are available, including both 35mm and 120 (MF). Once the black & white separations are processed, color transparencies or prints could be made from them using any of several processes, including IB Dye Transfer, Cibachrome silver dye bleach, offset printing, and several others, including digital ink jet, and other digital and analog printers. If there is any interest, let me know.

I only use my W3 for snap shots that aren't that important. For important shots and artistic photography, I only shoot medium format film. There's a wonderful lab in Toronto that will process or cross-process E6 stuff by 4pm if you get it to them before noon. No push/pull charge. For black and white film, I use dr5 in Colorado. Incredible results.
I took my TL-120 to Cuba, my Rolleidoscop to Israel, and my AGFA Samulette to Florida. With the Samulette I also took my Simda Panorascope. That one is the only non-medium format one...that one takes 16mm film.
You'll never achieve results as beautiful as film with a digital camera.

I thought Technicolor stopped doing IB dye transfer about 10 years
ago. Even if they were still doing it I can't imagine what it would
cost to get 120 length strips done.

Ctien (one of the last dye transfer printers) ran a final dye transfer
print sale on The Online Photographer
<http://theonlinephotographer.com/> and closed his darkroom this past
Spring/Summer.

Ilford Imaging Switzerland (the inkjet paper, and color products,
company with the Ilford name) has gone backrupt. The final batch of
Ilfochrome Classic was made in 2012.

Technicolor only did dye imbibition printing on motion picture film stock, not for the still image market. The Dye Transfer process for still images was pre-packaged by Kodak for many years under the Kodak Dye Transfer trade name. But, the basic process can be done by anyone or any company using standard stock chemicals and a suitable substrate (prints have been transferred to photographic film, paper, plastic, glass, and probably other materials as well. Patents have run out years ago, and these are all now in the public domain.

Cibachrome printing is currently done by The Lab Ciba, in Burbank, California. This process also is now in the public domain.

These were just listed as examples. There are many other processes by which black & white separations may be printed to color, in addition to chromogenic films and papers.
