Kodak SO-219, 7219, 5219 Image Structure, Curves, Modulation Transfer Function, Rms Granularity

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-tape transfer. For more information regarding TAF, see KODAK Publication No. H-9, TAF User's Guide.

IMAGE STRUCTURE

The modulation-transfer and diffuse rms granularity curves were generated from samples of 5219 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, KODAK Motion Picture Film available online at http://www.kodak.com/US/en/motion/support/h1.

Modulation Transfer Function

The "perceived" sharpness of any film depends on various components of the motion picture production system. The camera and projector lenses and film printers, among other factors, all play a role. But the specific sharpness of a film can be measured and is charted in the Modulation Transfer Function Curve.

rms Granularity:

Refer to curve.

Read with a microdensitometer, (red, green, blue) using a 48-micrometer aperture.

The "perception" of the graininess of any film is highly dependent on scene content, complexity, color, and density. Other factors, such as film age, processing, exposure conditions, and telecine transfer may also have significant effects.

The curves describe this film's response to red, green, and blue light. Sensitometric curves determine the change in density on the film for a given change in log exposure.4

Note: The exposure scale for VISION3 5219 / 7219 Film is longer than previous VISION and VISON2 Films. Because of the extended highlight latitude of and because we need to measure in this region, we expanded the exposure scale from a zero to four increment to a zero to five scale. In addition to the longer exposure scale, we are plotting twenty-one steps instead of twenty.

NOTICE: The sensitometric curves and data in this publication represent product tested under the conditions of exposure and processing specified. They are representative of production coatings, and therefore do not apply directly to a particular box or roll of photographic material. They do not represent standards or specifications that must be met by Eastman Kodak Company. The company reserves the right to change and improve
