Nov., 1932] TREATMENT OF NEW FILM 421
have indicated that damage due to these causes can be reduced very considerably; but a visit to almost any theater in which is being projected film that has been booked once or twice before and which has not been properly treated prior to its initial run, will disclose a screened picture marred by many scratches.
The buckling or warping of film is no inconsiderable item of film damage. The buckling or warping is either so bad that the picture can not be kept focused on the screen, or is insufficient to cause any trouble at all.
This kind of difficulty is likely to occur only with new film, unless the new film has been properly treated to obviate it, prior to its first screening; for it is due to the sudden withdrawal of moisture from the gelatin, or the swelling of the gelatin from being heated by the projection lamp and is not likely to occur with film that has been properly seasoned.
It is evident that the efforts, artistic and technological, that have been made in producing a picture, will all be for naught if the effects produced are marred by physical defects of the film that prevent a satisfactory screening, but which could be prevented by proper treatment. Nearly all the difficulties described here are in connection with improperly treated, or untreated film and such defects do not occur in film, the gelatin of which has been chemically seasoned prior to its initial screening.
When film is sent to a theater in which it will be passed through a projector for the first time, that theater is certainly entitled to receive film that has been thoroughly prepared for screening; and it should not be necessary for the projectionist to wax, oil, or otherwise treat the film so as to assure himself of an uninterrupted screening. Nor should the projectionist be held responsible for the oil that he must necessarily apply to film that is improperly prepared for screening when the accretion of emulsion causes the projector to protest loudly against overloading when pulling the film past the aperture. Some of the largest producers and distributors have found a relief from these conditions by chemically treating the film at their laboratories; and it seems safe to say that it would be the wish of every projectionist in the country that all new film be given a treatment that would produce as good results for them as are enjoyed by these companies, so that they could feel reasonably sure that no film would be damaged while in their charge.
