KODAK EKTACHROME 64T Color Reversal Film 7280 is a 64-speed color reversal motion picture camera film designed for exposure with tungsten illumination (3200 K). This film offers excellent color reproduction, fine grain, and high sharpness. 7280 has outstanding reciprocity characteristics, which give consistent color balance and speed over a wide range of exposures. EKTACHROME 64T Film should be processed in an E-6 Process.

KODAK EKTACHROME 64T Color Reversal Film 7280 has an acetate safety base. DARKROOM RECOMMENDATIONS
Do not use a safelight. Handle unprocessed film in total darkness. 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 the recommendations in ANSI/PIMA IT9.11-1998: for medium-term storage (minimum of ten years), store at 10"C (50"F) or lower at a relative humidity of 20 to 30 percent; for extended-term storage (for preservation of material having permanent value), store at 2"C (35"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 ANSI/PIMA IT9.11-1998, SMPTE RP131-2002, and KODAK Publications No. H-1, KODAK Motion Picture Film available online at http:// www.kodak.com/US/en/motion/support/h1, and No. H-23, The Book of Film Care. EXPOSURE INDEXES
Tungsten (3200 K) - 64 / Daylight (5500 K) - 401 Use these indexes with incident- or reflected-light exposure meters and cameras marked for ISO or ASA speeds or exposure indexes. These indexes apply for meter readings of average subjects made from the camera position or for readings made from a gray card of 18-percent reflectance held close to and in front of the subject. For unusually lightor dark-colored subjects, decrease or increase the exposure indicated by the meter accordingly. COLOR BALANCE
These films are balanced for exposure with tungsten illumination (3200 K). For other light sources, use the correction filters in the table below.

1 These are approximate corrections only. Some light sources are extremely variable. For critical applications, light source color temperature should be verified and test exposures should be performed.
Note: Consult the manufacturer of high-intensity ultraviolet lamps for safety information on ultraviolet radiation and ozone generation.
You do not need to make any filter corrections or exposure adjustments for exposure times from 1/10,000 to 1 second.
Process this film in KODAK Chemicals, Process E-6, cine machine only.
After processing, the product code number and other manufacturing identifications are visible along the length of the film.
When you transfer the film directly to video, you can set up the telecine using the KODAK EKTACHROME Telecine Analysis Film (TAF) supplied by Eastman Kodak Company. The TAF consists of a neutral density scale and an eight-bar color test pattern with a LAD gray surround.
The TAF gray scale provides the telecine operator (colorist) with an effective way to adjust subcarrier balance and to center the telecine controls before timing and transferring a film. The TAF color bars provide the utility of electronic color bars, even though they do not precisely match the electronically generated color bars. Using the TAF will help obtain optimum quality and consistency in the film-to-video transfer. For more information regarding TAF, see KODAK Publication No. H-822, KODAK Telecine Analysis Film User's Guide.
The modulation-transfer curves, and the diffuse rms granularity data were generated from samples of 7280 Film exposed with tungsten light filtered to 3200 K and processed as recommended in Process E-6 chemicals.
