EASTMAN High Contrast Positive Film II 5363 and 7363 is a medium speed black-and-white positive film that is suitable for making both positive and negative titles. It is also useful for production of printer effects, such as silhouette and traveling mattes. This blue-sensitive film is characterized by high contrast, excellent sharpness, and very high resolving power.

Base

This film has a clear acetate safety base with an antihalation undercoat. The backside has an anti-static coating with a lubricant.

Darkroom Recommendations

Use a KODAK OC Safelight Filter / greenish-yellow with a 15-watt bulb, no closer to the film than 1.2 meters (4 feet).

Storage

Store unexposed film at 13°C (55°F) or lower. For extended storage, store at -18°C (0°F) or lower. Process exposed film promptly. Store processed film according to recommendations in NAPM IT9.11-1992: for medium term storage (minimum of ten years), store at 25°C (77°F) or lower, at a relative humidity of 20 to 50 percent; for extended-term storage (for preservation of material having value), store at 21 °C (70°F) or lower at a relative humidity of 20 to 30 percent. For active use, store at 25°C (77°F) or lower, at a relative humidity of 50 +5 percent. This relates to optimized film handling rather than preservation; static, dust-attraction and curl-related problems are generally minimized at the higher relative humidity. After use, return the film to the appropriate medium- or long-term storage conditions as soon as possible.

For more information about medium and long-term storage, see NAPM IT9.111992, and KODAK Publications H-1, KODAK Professional Motion Picture Films, and H-23, The Book of Film Care.

Gamma

This film should be developed to a recommended control gamma of 2.90 to 3.20 (Status M Densitometry with a blue filter).

Available Roll Lengths

For information on film roll lengths, check Kodak's Motion Picture Camera Films Price Catalog or see a Kodak sales representative in your country.

Processing

The following are starting-point process recommendations for most conventional continuous-immersion processors with solutions prepared according to the formulas in KODAK Publication No. H-24-15, Manual for Processing EASTMAN Motion Picture Films, Module 15. The processing times may require modification for a particular machine.

Notice: Observe precautionary information on product labels and on Material Safety Data Sheets.

* Agitation in the developer and fixing bath should be by recirculation through submerged spray jets that impinge the film strands.

§Many factors affect drying: air temperature, relative humidity (RH); volume, rate and distribution of the air flow; final squeegeeing, etc. In a conventional convection-type drying cabinet with air at about 35°C (95°F) and 40- to 50-percent RH, drying will take 15 to 20 minutes. In an impingement-type drying cabinet, with a higher temperature and lower RH, drying time is greatly reduced. With either type of dryer, the film should be dry without tackiness 1/2 to 2/3 of the way through. Upon cooling to room temperature after leaving the dryer, the film should be at equilibrium with the room air at approximately 50-percent RH.

Diffuse RMS Granularity* 10

*Read at a net diffuse visual density of 1.0, using a 48-micrometer aperture.
+ Determined according to a method similar to the one described in ISO 6328-1982, Photography-Photographic Materials- Determination of ISO Resolving Power.
