A two-color process. Orthochromatic and panchromatic B/W negatives, bipacked emulsion-to-emulsion in the camera, were exposed simultaneously, and then printed on a single strip of film with emulsion applied to both sides. Subsequently treated to produce red-orange images on one side, and blue-green images on the other.

History

At NIKFI ((НИКФИ/ Scientific Research Institute of Cinema and Photography), a laboratory dedicated to the development of color film systems was set up in February 1931, not long after the Institute became operational, in the latter months of 1930. Located in Moscow, the aim of the lab was for the USSR to achieve greater autonomy across various technical areas of cinema and photography, especially in the manufacture and processing of film. The lab was led by Natan Ovechkis (main specialist), Nikolai Fedorov (head of the lab) and Nikolai Agokas. The first report on the work of the lab was published in December 1931 (Skavronskii, Agokas & Fedorov, 1931). Initially, NIKFI researchers carried out experiments using foreign-made film products and were leaning towards adopting a subtractive two-color process similar to those developed by German companies (such as the Ufacolor process). Highly confident at the time of the 1931 report, the authors mentioned they had ordered a double-coated print film from a new film manufacturer (later named Svema) based in Shostka, Ukraine, and were in talks with Soiuzkino (Союзкино, the Soviet state film production group) regarding the production of a series of color short films. 

Ultimately, the double-coated print film stock was imported from Germany (Agfa Dipo film), as was the negative (Agfa Bipack film) – both products used for the German Ufacolor process. Extensive research efforts towards developing a homegrown bipack film at NIKFI apparently failed to move beyond the experimental stage (Kolosov & Kuznetsov, 1937). In addition to Agfa Bipack, the Soviets also used Eastman Kodak Bipack – on Artek (1937), for example (Maiorov, 2016). Another obstacle the Soviets faced, stemmed from the development of the technology required for toning. It was designed from scratch at NIKFI, and a model that could be run under studio conditions was eventually built by Fedor Provorov (Ovechkis, 1936).

In the end, the team moved to the commercial production stage not with Soiuzkino, but with its competitor, the Mezhrabpomfilm studios in Moscow. Fedor Provorov, an architect by training who joined NIKFI in 1931, became head of Mezhrabpomfilm’s color lab, technical director for color shoots and also performed duties as a camera operator. Together with director Nikolai Ekk and assistant operator Georgii Reisgof, Provorov presented an experimental film, Karnaval tsvetov (Carnival of Flowers), to the general public in September 1935. The film brought together, according to the film’s narrator, the “successes and failures” of color rendering. The film opened with demonstrations of “static color”, with reproductions of painted canvases (portraits of the country's leaders, genre scenes, landscapes), sculptures on colored backgrounds and posters. The film went on to present “color in movement”: beginning with military manoeuvers, sports and a May Day parade on Moscow’s Red Square (including a close-up of a red flag flying against a sky above the Kremlin); which were then followed by Labour Day night-time illuminations, and, finally, some folk dance performances.

The final part of Karnaval tsvetov, “Autumn in the South”, was shot in Georgia. It featured alternating close-ups and general shots, with an emphasis on blues and oranges: sea, sky, mandarin picking and sunset. Cinematographer Aleksandr Golovnia published a negative review, criticizing the film for its lack of depth and relief, its “all-pervading aniline tints” and the omnipresence of red and green [sic] tones (Golovnia, 1935). 

Karnaval tsvetov was made as a test for the production of the first color feature film by the same team, Grunia Kornakova, which was released in June 1936. Sixty prints were reportedly printed in color on the only color printing machine existing in the USSR, at the rival studios' laboratory, Mosfilm. In spite of their public acclaim, these two-color films received little support from the state film industry's governing body because the development of the three-color method was prioritized at that time (Cavendish, 2016). After making a short documentary on the Artek children's camp, Provorov and his collaborators were reassigned to Mosfilm.

The NIKFI two-color process continued to remain in use until 1941, mainly at Mezhrabpomfilm’s successor Soiuzdetfilm and Mostekhfilm studios, but with minimal resources for producing short non-fiction and animated films. Related two-color technology was also in limited use in the Kiev and Leningrad film studios (Deriabin, 2002; Cavendish, 2021). From 1937 onwards, Eliazar Rozenfeld became the principal in charge, while pursuing a thesis in photographic chemistry at NIKFI. He worked on developing alternative reagents, in particular to find a replacement for uranyl nitrate, which was used in the toning process and was prohibitively expensive to import. He also developed a strengthener to compensate for defects at the various stages of processing, as well as a weakener (Luchanskii, 1939: pp. 41–4). 

In 1938, in collaboration with the Moscow Newsreel Studios, Soiuzdetfilm also produced a film featuring a culture parade Tsvetushchaia molodost (Blooming Youth) for the twentieth anniversary of the Komsomol (Communist Youth League), and two short films on the monuments of Samarkand, Registan and Pamiatniki èpokhi Timura (Monuments to Timur) for the educational film studios Mostekhfilm. Konek-Gorbunok (The Little Humpbacked Horse) (1941) seems to have been one of the last ambitious productions shot using this process in the USSR. The film was released with only five prints in August 1941 – it was distributed again in 1943.

NIKFI and the State Committee for Cinematography both remained ambivalent about this two-color process. In principle, it was considered unsuitable for rendering the full range of colors, and it was deemed necessary to be replaced by a three-color process. Nonetheless, from a pragmatic point of view, it was the only Soviet-produced process that had thus far enabled color films to be produced.

Technology

The NIKFI two-color process initially used Agfa bipack negatives and double-coated print film. Later, similar products from Eastman Kodak were used. As such it is similar to many two-color processes developed at the same time around the world, such as Ufacolor, in Germany, and Cinecolor in the United States.

The following description is drawn from Natan Ovechkis (Ovechkis, 1936):

Using a regular camera, we shoot using two films stacked one on top of the other, emulsion against emulsion. The front film has an emulsion layer that is sensitive to blue-green light (orthochromatic), while the back film is sensitive to all the colors of the spectrum (panchromatic). To ensure that red-orange colors are recorded on the back film, the front film contains a red-orange dye in or above the emulsion layer (in the form of a special layer), which acts as a light filter and stops blue-green rays. This creates two separate negatives.

The positive is printed from the two negatives using a special film coated with emulsion on both sides. The side of the positive that contains the image printed from the negative exposed through the red-orange light filter, is turned blue by a special treatment called iron toning; the other side of the positive is treated with uranyl nitrate toning to obtain an orange colour.

It is difficult to say whether all the chemicals required for printing were imported, or if some were adapted or ‘reinvented’ locally from the outset, before being replaced by others, or whether the process was really an improvement in comparison to initial prototypes and to what extent, if any, it differed.
