PAN OR SuPER-PAN Ortho Reversal, with a speed of 19 Scheiner or soo H & D, and 23 3 Scheiner or 1,300 H & D. QUALITY Quality and definition good, with a tendency towards bright, contrasty results. Freedom from halation. Fineness of grain. These remarks apply to both Ortho and Panchromatic film and the colour sensitivity is high in both grades of emulsion, although the Panchromatic film is, of course, sensitive to a wider range of the spectrum. It should be noted that the Panchromatic grade is only super-pan film available in the 8mm. size. Ortho Reversal, per spool, processing 3/per spool. Panchro super Reversal 6/per spool, processing 3/9 per spool. PrIcz 4/6 GENERAL REMARKS. Apart from its excellent quality. and its suitability for home processing the outstanding feature of Gevaert 8mm. is the patented method of scoring the film to enable it to be separated after processing. As will be well known, 8mm. is purchased in the form of 16mm. film with double the number of perforations. This film is first exposed all down one side and then all down the other and after processing the film is slit in half longitudinally, giving a total length of 50 ft. of 8mm., which, in showing time, is equivalent to 100 ft. of 16mm. The original sponsors of the 8mm. system patented the method of separation and rejoining in the | 1 In this feature, which appears regularly in “Amateur Cine World,” new apparatus likely to bz helpful to the amateur worker is critically reviewed—judged solely on merit and from the standpoint of usefulness. such a manner that it was not possible for the home-processor to use this type of film. The Gevaert method enables a user to process his film at home in the normal way and then, with no more complicated instrument than his own finger and thumb to split the film into two 8mm. strips. This is made possible because the film is scored down its centre with a thin line which fractures smoothly when the film is bent. Some roughness might be expected at this fracture, but we have found on test that the edge is smooth and offers no resistance when passing through the projector. We also found the base to be tough and very resistant to wear after repeated projection. We have received for test a sample of Agfa Isopan Supersensitive film, which is to supersede Novopan. This will be reviewed next month. WHAT DO SPEED YOU NEED? Relatively all Agfa films are fast and ISOPAN S:S. fine grain has the distinction of being the fastest 16mm. film available. It makes possible work under conditions hitherto impossible, and under normal lighting gives a new and more beautiful rendering. LATITUDE An inherent characteristic due to the special Agfa processing— errors of exposure are more easily corrected with Agfa and your films are more successful than ever. RICHNESS 5 COLOUR RENDERING An essential with reversible film. A deep velvety richness of the shadows and a clear brilliant sparkle in the headlights are consistent with Agfa ISOPAN S:S. film. All Agfa films give particularly good colour rendering without recourse to filters, while with suitable filters some beautiful effects can be secured. Weak film scratches easily and tears at the sprocket holes.
