EASTMAN EXR 500T Film 5298

1) Description

EASTMAN EXR 500T Film 5298 (35 mm) is a high-speed tungsten-balanced color negative camera film with

microfine grain, very high sharpness, and high resolving power. It feature wide under and over exposure latitude,

with whiter whites, and accurate color and flesh-to-neutral reproduction. Enhanced shadow detail provides crisper,

richer blacks. It also offers improved shadow detail and blacks in telecine transfers. This film reproduces a wide

range of colors for increased performance in special-effects applications.

2) Base

EASTMAN EXR 500T Film 5298 has an acetate safety base with rem-jet backing.

3) Darkroom Recommendations

Do not use a safelight. Handle unprocessed film in total darkness.

4) Storage

Store unexposed film at 13ºC (55ºF) or lower. For extended storage, store at -18ºC (0ºF) or lower. 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 10ºC (50ºF) or lower at a relative humidity of 20 to 30 percent; for extended-term

storage (for preservation of material having permanent value), store at 2ºC (35ºF) or lower at a relative humidity of 20

to 30 percent. For active use, store at 25ºC (77ºF) 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 No.

H-1, EASTMAN Professional Motion Picture Films (1992 Edition) and No. H-23, The Book of Film Care (1992

Edition).

5) Exposure Indexes

Tungsten (3200K) - 500/28 Daylight¹- 320/26

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 (such as one of the KODAK Gray Cards, KODAK

Publication No. R-27) held close to and in front of the subject. For unusually light- or dark-colored subjects, decrease

or increase the exposure indicated by the meter accordingly.

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.

8) Reciprocity Characteristics

You do not need to make any filter corrections or exposure adjustments for exposure times from 1/1000 to 1 second.

9) Processing

Most commercial motion-picture laboratories provide a processing service for this film. There are no packaged

chemicals available for preparing the processing solutions. See KODAK Publication No. H-24.07, Manual for

Processing EASTMAN Color Films, Process ECN-2 Specifications, Module 7, for more information on the solution

formulas and the procedure for machine processing these films. Normal processing is recommended for all exposure

levels of this film.

10) Identification

After processing, the product code number 5298 (35 mm) emulsion and roll number identification,

KEYKODE number, and internal product symbol (T) are visible along the length of the film.

11) Laboratory Aim Density (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, negative originals should be

timed relative to Laboratory Aim Density (LAD) Control Film supplied by Eastman Kodak Company.²The LAD

Control Film provides both objective sensitometric control and subjective verification of the duplicating procedures

used by the laboratory.

In the LAD Control Method,³the electronic color analyzer used for color timing is set-up with the LAD Control 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.

12) Film-To-Video Transfers

When you transfer the film directly to video, you can set up the telecine using the negative 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-9, TAF User's Guide.

²Direct any inquiries to one of the regional sales offices.

³Use of the LAD Control Method is described in the paper, "A Simplified Motion-Picture Laboratory Control Method for

Improved Color Duplication," by John P. Pytlak and Alfred W. Fleischer in the October 1976 SMPTE Journal.

13) Image Structure

The modulation-transfer curves, the diffuse rms granularity, and the resolving-power data were generated from

samples of 5298 Film exposed with tungsten light and processed as recommended in Process ECN-2 chemicals. For

more information on image-structure characteristics, see KODAK Publication No. H-1, EASTMAN Professional

Motion Picture Films.

NOTE: These photographic modulation-transfer values were determined by using a method similar to the one

described in ANSI Standard PH2.39-1977(R1984). The film was exposed with the specified illuminant to spatially

varying sinusoidal test patterns having an aerial image modulation of a nominal 60 percent at the image plane,

with processing as indicated. In most cases, the photographic modulation-transfer values are influenced by

development-adjacency effects and are not equivalent to the true optical modulation-transfer curve of the emulsion

layer in the particular photographic product.
