Techniscope resurgence!

Techniscope: 2-perf 35mm for straight to letterbox films.
Developed by Technicolor Italiana, l in 1962 by Dr. Giulio, it's hey day was in the 70's with Sergio Leones spaggetti westerns but 100's of films were shot this way. Modern post production techniques & telecine are today's pitfalls with this format, and when you can find a modified camera it's probably an old and noisy Arri 2c (though not as loud as running it at 4 perf!). Pros: you can use standard lenses and it will halve your stock and processing costs: still the cheapest way to shoot 1:2.37, 'scope.

1962: Technicolor Italy introduced Techniscope, a 2-perf 35mm spherical format (half-frame). This was blown-up and strectched to 4-perf 35mm anamorphic during the process of making the b&w matrices for their dye transfer process. Techniscope died out when Technicolor killed off their relativly grain free dye transfer process in the mid 1970's. However, with modern film stocks, DI and dupe stocks getting better, there has been an attempt to bring it back as "Multivision 235" by a lab in Australia. The low-budget indie film The Slaughter Rule used this format and blew-up to scope.
