To Scott:
To 100% I would like to agree with your statement. The requirements for optical printing require an increase of 60% image cleanliness in the negative. In contact printing, many dust grains would remain invisible. All of the labs were reluctant to switch to Bell & Howell Model C in the contact process due to the rejects and too slow printing on serial production on subtractive optical printers. As a rule, 65mm negatives in the same format take 1 to 1 prints. In the case of the Ultra Panavision films, however, they worked together with the Technicolor laboratories, because variable rectified prints (more compressed at the edles) were required for Ultra Panavision/70mm Cinerama prints (THE GREATEST STORY EVER TOLD) or even copied spherically (FALL OF THE ROMAN EMPIRE). After the start of the additive serial copying in contact printing with CLEOPATRA (A/B and C reels) at DeLuxe 1963, the labs Technicolor, Rank Film and LTC St. Cloude also switched to additive printung in the contact process. At least for the European copy Labs, especially for Technicolor in London or in Rome, I know that. As you already argue for medium format photography, this also applies to the film printing: the purity of the colors was unsurpassed in the additive printing process! In the subtractive and optical printing it came again and again to impurities of complementary colors. The effort also for the preparation of the original negatives extremely questionable (treatments for 35mm for example).
It is therefore an absolute feat as Technicolor has succeeded in producing perfect 70mm prints as well as perfect 35mm Scope prints of Technirama negatives. And it's just one disaster that has been released in recent years in Burbank on behalf of the 70mm movie.
