Amateur Cine World (September 1934)

Sesion A shot of this kind looks well—if not held on too long, a rule to remember in cine portraiture. there are any dull water marks on the back of the film, they should first be removed by means of a chamois leather moistened in methylated spirits. At the present time there are two good positive stocks on the market, made by Pathe and Gevaert. The negative and positive films are now threaded through the gate with their emulsion sides facing, and the gate closed. The makers’ instructions must now be followed as to the operation of the printer, usually the exposed positives and developed negatives are collected PROCESSING 9.5 mm. ““ Neg-Pos” Film at Home (Continued from previous page) in a bin placed underneath the printer, to be re-wound later. Unfortunately, positive film is now only obtainable in 30 foot lengths and the makers would do well to market this stock in roo foot lengths for printing. When the exposed film has all run through the printer, it is rewound ready for development. Tests should be made first, before the whole reel is exposed to find out what intensity of printing light will be required for the various scenes. The positive film is developed in exactly the same way as the negative, with the exception that a developer which will give more contrast must be used. The following will be found to give excellent results with the two positive stocks mentioned above.

The positive is then fixed and dried as described for negative film. When it is quite dry it is cleaned and is then ready for projection. When winding the positive on to the projection spool, it should be remembered that a print is projected with the emulsion facing away from the screen, ie., the opposite way round to a direct reversal film. An article on how to process 9.5mm. reversal film at home appeared in the July issue of ‘‘ Amateur Cine World,” a few copies of which can still be obtained from the Publisher. East Mudlands Federation N our last issue we gave details of the East Midlands | Federation of Amateur Cine Societies, formed on June 3rd, with the object of linking together moviemakers within a radius of fifty miles of Nottingham.
