K OD AK VISION2 500T Color Negative Film 5218 / 7218 / SO-218

March 2006 • H-1-5218t

KODAK VISION2 500T Color Neg ativ e Film 5218 / 7218 / SO-218 is a high-speed, tungsten-balanced color negative film with the finest grain a vailable in a 500T product. The toe speed has been optimized to give enhanced shadow detail and improved shadow neutrality. It delivers true, natural color over a wide range of exposures. The curve shape of this film is very linear contributing to the overall neutrality and flesh-to-neutral tone reproduction. This film delivers improved performance for special effects and digital compositing. The neutral tone scale provides easier color timing and grading in postproduction. KODAK VISION2 500T Color Negative Film delivers clean, crisp images.

BASE

KODAK VISION2 500T Color Negative Films 5218 and 7218 have an acetate safety base with rem-jet backing.

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 (3200K) - 500 Daylight1 - 320

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 (3200K). You can also expose them with tungsten lamps that have slightly higher or lower color temperatures (+/- 150K) without correction filters, since final color balancing can be done in printing. For other light sources, use the correction filters in the table below.

These are starting-point recommendations for trial exposures. If the kind

IDENTIFICATION

After processing, the product code numbers 5218 (35 mm), 7218 (16 mm), or SO-218 (16, 35, and 65 mm; edgeprint shows 0218) emulsion, roll, and strip number identification, KEYKODE Numbers, and manufacturer/film identification code (EH) are visible along the length of the film.

Use this table for average subjects that contain a combination of light, medium, and dark colors. When a subject includes only pastels, use at least 1/2 stop less exposure; dark colors require 1/2 stop more exposure.

Lighting Contrast -

The recommended ratio of key-light-plus-fill-light to fill light is 2:1 or 3:1. However , you may use 4:1 or greater when a particular look is desired.

RECIPROCITY CHARACTERISTICS

You do not need to make any filter corrections or exposure adjustments for exposure times from 1/1000 to 1/10 of a second. If your exposure is in the 1 second range, it is recommended that you increase your exposure by 2/3 stop and use a KODAK Color Compensating Filter CC 10R. If your exposure is in the 10-second range, it is recommended that you increase your exposure by 1 stop and use a KODAK Color Compensating Filter CC 10R.

PROCESSING

Process in Process ECN-2.

Most commercial motion-picture laboratories provide a processing service for these films. See KODAK Publication No. H-24.07, Processing KODAK Color Negative Motion Picture Films, Module 7 available online at http:// www.kodak.com/US/en/motion/support/processing/ h24m7.shtml, for more information on the solution formulas and the procedure for machine processing these films. There are also pre-packaged kits available for preparing the processing solutions. For more information on the EASTMAN ECN-2 Kit Chemicals, check Kodak's Motion Picture Films for Professional Use price catalog.

LABORATORY AIM DENSITIES (LAD)

To maintain optimum quality and consistency in the final prints, the laboratory must carefully control the color timing, printing, and duplicating procedures. To aid in color timing and curve placement, negati ve originals should be timed relative to Laboratory Aim Density (LAD) Control Film supplied by Eastman Kodak Company. Film provides both objective sensitometric control and subjective verif ication of the duplicating procedures used by the laboratory.

In the LAD Control Method,

used for color timing is set-up with the LAD Cont rol Film to produce a gray video display of the LAD patch, corresponding to 1.0 neutral density (gray) on the print. The negative printing original is then scene-to-scene timed. There are specific LAD values for each type of print or duplicating film that the original can be printed on. For print films, the LAD patch is printed to a neutral gray of 1.0 visual density. For duplicating films, the specified aims are at the center of the usable straight-line portion of the sensitometric curve of the film.

Due to normal variations in exposure and processing of color negative films, particular scenes may not print exactly at the same printer lights as the LAD Control Film. The LAD Control Film is intended as a set-up tool for electronic color analyzers and printers. It is NOT a reference that every scene must match. Normal film-to-film and scene-to-scene exposure variability is accommodated by the color timing (grading) process, on an electronic color analyzer set up with the LAD Control Film. Normally exposed and processed color negatives will typically print well within the range of an additive printer setup with the LAD Control Film, although SIGNIFICANT or UNEXPECTED departures from this center point balance may indicate an exposure/ filtration problem with the cinematography or with the process control. Some specialized films and/or specialized negative processing techniques (push-processing, pull-processing, "skip-bleach" processing, etc.) may require more extreme adjustment from the LAD printing condition to attain desired results.
