Single 8 is at the Hannover Messe 1966 imagined by the Japanese company Fuji cine-film system ( film format ). It was and still is in Japan the dominant cine system, but little used in Europe and hardly known.
Commonality with Super 8
Single 8 uses the same film format, so the same image size and the same perforation as the recently introduced by Kodak Super 8 system. Therefore, no special projectors are needed for single 8, the films can be demonstrated at any Super 8 projector. Also, most single- 8- tapes contain 15m film, which results in the standard frame rate of 18 frames per second 3min 20s duration.
Super 8 and Single 8 use completely different cartridges, which has fundamentally different design according cameras, which can then in principle be loaded only with the cassette of the respective system. As a rare exception to this principle, a camera of the brand Elmo was available on the Japanese market, which could use both types of cassettes.
At the Super 8 cartridge unwinding and coiling roller are arranged side by side, resulting in a correspondingly thick cassette according. But above all, it does not allow its construction actually rewind the movie as it is interesting for various film tricks. However, some cameras can be about 90 pictures back jam in the free cassette space, which is sufficient for transitions. The instruction manual usually recommends but from having to do it at the end of the film.
In Single-8 cartridges are the two roles - similar to the audio compact cassette - on separate axes to each other, whereby the cartridge correspondingly thin fails. Overall, the volume of the Single-8 cartridge is significantly lower than that of the Super 8 cartridge. The cassette allows unlimited Rewind, the best camera model from Fuji ( FUJICA ZC 1000) even allows the backward films. The unproblematic Rewind was emphasized from the outset in advertising. For the camera-side pressure plate the Single-8 cartridge has a recess.
Film pressure plate
Another difference between the two systems is that Kodak has waived at the Super 8 for the sake of a simple insertion of the cassette into the camera on a camera's own film pressure plate; the film swims with virtually no proper contact pressure in a narrow channel, which is formed from the film guide plate in the cassette and the camera-side counterpart. A cassette imprecise produced can easily cause an irregular image steadiness, sharpness defects and pump the sharpness are common. Single-8 cameras have against it ( like almost every other film cameras as well) over a camera's own, metal film pressure plate without affecting the loading of the cartridge would be significantly more difficult.
The coils of a single 8- cassette and thus the entire cassette are kept very small. The reason offered by Fuji Single 8 original footage used instead of the usual Super 8 Acetatmaterials as film supports a polyester material that is 1/3 thinner, yet more dimensionally stable and resistant to tearing. This makes it possible that in the Single 8 film cartridge as well as in a Super 8 cartridge 50 feet/15 m film are included. Polyester film, however, can not cut the film with Filmkitt ( = " wet" ), but only with transparent films ( = " dry" ) stick. Since polyester film, however, does not shrink as acetate material, has no such disadvantages ( light gap formation ) as the case of bonded films with acetate film. The application of a Magnettonspur is not possible with the "normal" glue so that the world apparently only Fuji (Japan), Ingo Reinsdorf ( Germany ) and Chris film technique ( Germany ) soundtracks may apply. Due to the different thickness it is not advisable also, zusammenzuschneiden acetate and polyester film material, but this is essentially possible.
Fuji's Single 8 film exists currently still in two variations: as R25N ( daylight film with a sensitivity of ISO 25/15 ° ) and as RT200N ( tungsten film ISO 200/24 ° ); both materials are developed only by a laboratory Fuji and a laboratory of the company Retro8 (both in Tokyo ).
Fuji, however, has announced that it would no longer offer these films and their development. Selling for R25N is currently March 2012, for the RT200N May 2010, the development by Fuji should still be guaranteed until at least September 2013. Sound film cartridges that allow it to be incorporated into special sound cameras simultaneously with the image tone on Magnettonrandspur (s ), there are at Single 8 as at Super 8 for years no longer. Was also set by Fuji selling vorbespurtem material in standard cassettes ( R25M and RT200M ) for the overdubbed sound.
The Japanese company Retro Enterprises, through which also the Fuji - film material can be sent to the development, but now offers an alternative to Fuji Velvia slide film 50 (ISO 50/18 ° ) is assembled under the name Cinevia as a single 8 film. This material is - as well as the now placed also under the name Cinevia to market Super 8 film on Velvia 50 base - developed in the common E6 process. It should therefore no longer be sent to the development of Japan and is otherwise available in Germany. However, the Cinevia single 8 film used as well as the Super 8 variant as acetate film base. This offers the advantage that the film section, a wet adhesion is possible. On the other hand, the Single-8 cartridge when Cinevia because of the thicker film carrier only 40 meters Fuß/12 film, so that the running time to 2 minutes 40 seconds per cassette is reduced (at 18 frames per second). For fall 2007, another " Cinevia " Single-8 color reversal films have been announced:
- Cinevia T64 Professional Single-8 ( Fujichrome T64 Professional ISO 64/19 °, Tungsten film, available since about 2008, in Germany )
- Cinevia / Astia 100F ( Fujichrome Astia 100F, ISO 100/21 °, daylight film, since about 2008 also available in Germany )
- Cinevia / Provia 400X ( Fujichrome Provia 400X, ISO ISO 400/27 °, daylight film, apparently also 2009 not yet available)
Black -and-white films that no longer existed for a long time in Single-8 cartridges are available once again for some time. Retro Enterprises provides them with 12 m SW- acetate film from German production of (sensitivity to ISO 200/24 °).
The company also announced Single8film.com had to offer from the summer of 2006 Single8 empty cartridges with codes for all 5 film speed, which can then be filled with Super8 meter. Since Fuji but continues to offer its R25N/R200N, these plans are (for now) from the table.
