DESCRIPTION
EASTMAN Fine Grain Release Positive Film 5302 (35 mm) and 7302 (16 mm) is a low-speed, high-resolution print film. This blue-sensitive black-and-white film is designed for general release printing. It is also useful for making both positive and negative titles, and dubbing prints for sound.
BASE
This film has a clear acetate safety base with anti-static protection, and a base thickness of 5.6 mils. In addition, 7302 Film has an anti-curl layer applied to the base.
DARKROOM RECOMMENDATIONS
Use a KODAK OA Safelight Filter / greenish yellow, with a 15-watt bulb, no closer to the film than 1.2 metres (4 feet).
STORAGE
Store unexposed film at 13˚C (55˚F) or lower. For extended storage, store at -18˚C (0˚F) or below. Process exposed film promptly. Store processed film according to the 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 permanent value), store at 21˚C (77˚F) or lower at a relative humidity of 20 to 50 percent; for extended-term storage (for preservation of material having permanent 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 usage, the film should be returned to the appropriate medium- or long-term storage conditions as soon as possible.
For more information about medium- and long-term storage, see NAPM IT9.11-1992, and KODAK Publications H-1, KODAK Motion Picture Film, and
H-23,The Book of Film Care.
PRINTING CONDITIONS
You can make satisfactory prints using negatives of average density if run on a continuous additive printer (such as a Bell
&Howell Model C) at 180 feet per minute, equipped with a 1000-watt lamp at 80 volts dc (85 volts for 35 mm) and a ground glass in the beam. Typical starting-point printer settings are as follows:
| Trim Setting | Tape Setting |
| | | | |
Beam | 16 mm | 35 mm | 16 mm | 35 mm |
| | | | |
Red | 17 | 21 | 32 | 24 |
| | | | |
Green | 17 | 21 | 32 | 24 |
| | | | |
Blue | 17 | 21 | 32 | 24 |
| | | | |
For laboratories with subtractive printers, such as a
Bell & Howell Model J, use the following starting-point recommendations for 16 mm film: 1000-watt lamp at
55 volts dc and a printer speed of 62 feet per minute. For 35 mm films with a Bell & Howell Model D Printer, use these starting-point recommendations: 500-watt lamp at
75 volts dc and 90 feet per minute. For both 16 and 35 mm setups, use a neutral density filter (such as the KODAK WRATTEN Neutral Density Filter, No. 96) with a density of 0.50 in the beam and a diaphragm setting of 13.
SOUND-TRACK PRINTING
A variable-area positive silver sound track can be printed on 5302 / 7302 Film from a negative sound record on EASTMAN EXR Sound Recording Film 5378™ / 7378™. The optimum variable-area sound-track density for the print lies between 1.2 and 1.4, measured visually for both 16 and
35 mm films. This print density is chosen to provide a good compromise between signal-to-noise ratio and frequency response. The densities of the sound-track negatives required to produce optimal print densities are determined by using recognized cross-modulation test procedures.
