EASTMAN Fine Grain Duplicating Positive Film 5366 (35mm) and 7366 (16mm) is a low-speed duplicating film intended for making master positives from black-and white camera negatives which when printed onto EASTMAN Fine Grain Duplicating Panchromatic Negative Film 5234 and 7234, produces duplicate negatives that are only distinguishable from the originals by skilled observers. This blue-sensitive black-and-white film has very high resolution and incorporates a yellow dye, which is removed during processing, to provide very high acutance.

Base

This film has a clear acetate safety base.

Darkroom Recommendations

Handle unprocessed film in total darkness. If necessary, you can examine the film for less than one minute, using the following safelight combination: a 15-watt bulb and KODAK OC Safelight (greenish-yellow), no closer than 4 feet (1.2 meters) to the film.

Storage

Store unexposed film at 13°C (55°F) or below. Process exposed film promptly. Store processed film at 21 °C (70°F) or lower at a relative humidity of 40 to 50 percent for normal commercial storage. For more information on long-term storage conditions, see KODAK Publications No. H-1, EASTMAN Professional Motion Picture Films, and No. H-23, The Book of Film Care.

Exposure

For laboratories with subtractive printers, such as a Bell & Howell Model D Printer, these recommendations should be helpful as a starting point. Use a 500-watt tungsten lamp operating with a diffuser at a lamp setting of 75 volts. With a printer speed of 90 feet per minute and a diaphragm setting of 15,satisfactory master positives should be produced from original negatives of average density. (The maximum density of the negative image should produce a density of about 0.6 to 0.8 in the master positive, i.e., just above the lower end of the straight-line portion of the characteristic curve.)

Processing

The following starting-point recommendations are for a typical continuous immersion processing machine. See KODAK Publication No. H-24.01, Manual for Processing EASTMAN Motion Picture Films, Module 1, for more information on solution formulas and procedures for machine processing.

* Agitation in the developer and fixing bath should be by recirculation through submerged spray jets that impinge on the film strands.
+ Develop to recommended control gamma of 1.2 to 1.6 calculated using Status M densitometry (blue).
** Fixer-laden water from wash tank, pH about 6.
§Drying depends on many factors such as air temperature, humidity, volume and rate of air flow, flow distribution pattern, final squeegeeing, etc. In a typical motion-picture film drying cabinet with air at about 95°F (35°C) and 40- to 50-percent relative humidity (RH), satisfactory drying will require 15 to 20 minutes. Film leaving the drying cabinet when it has reached room temperature should be at equilibrium with room air at approximately 50-percent RH.

Identification

After processing, the product code number 5366, emulsion and roll number identification, and internal product symbol (D) are visible along the length of the film.

Image Structure

The modulation-transfer curve, rms granularity, and resolving power data were generated from samples of EASTMAN Fine Grain Duplicating Positive Film exposed to tungsten light and processed in KODAK Developer D-96 at 21 °C (70°F) to the recommended control gamma. For more information on image structure characteristics, see KODAK Publication No. H-1, EASTMAN Professional Motion Picture Films.
