Kodak 7229, 5229 Sensitometric Curves, MODULATION-TRANSFER Curves, Diffuse RMS Granularity Curves

SENSITOMETRIC CURVES ➤

"0" on the x-axis represents normal exposure of an 18-percent gray card in the red, green, and blue layers of this film. A white card is 2 1/3 stops higher than normal exposure, and there are at least 2 1/2 stops above that for capturing specular highlight detail.

A 3-percent black card is 2 2/3 stops below normal exposure. There are at least 2 1/2 stops of latitude below that for capturing shadow detail.

RECIPROCITY

No filter corrections or exposure adjustments for exposure times from 1/1000 of a second to 1/10 second. In the 1-second range, increase exposure 2/3 stop and use a KODAK Color Compensating Filter CC 10Y. In the

10 second range, increase exposure 1 stop and use a KODAK Color Compensating Filter CC 20Y.

MODULATION-TRANSFER CURVES ➤

This graph shows a measure of the visual sharpness of this film. The x-axis, “Spatial Frequency,” refers to the number of sine waves per millimetre that can be resolved. The y-axis, “Response,” corresponds to film sharpness. The longer and flatter the line, the more sine waves per millimetre that can be resolved with a high degree of sharpness—and the sharper the film.

DIFFUSE RMS GRANULARITY CURVES ➤

To find the rms granularity value for a given density, find the density on the left vertical scale and follow horizontally to the sensitometric curve and then go vertically (up or down) to the granularity curve. At that point, follow horizontally to the Granularity Sigma D scale on the right. Read the number and multiply by 1000 for the rms value.

SPECTRAL-SENSITIVITY CURVES ➤

These curves depict the sensitivity of this film to the spectrum of light. They are useful for determining, modifying, and optimizing exposure for blue- and green-screen special-effects work.

SPECTRAL DYE-DENSITY CURVES ➤

These curves depict the spectral absorptions of the dyes formed when the film is processed.

They are useful for adjusting or optimizing any device that scans or prints the film.

NOTE: Cyan, Magenta, and Yellow Dye Curves are peak-normalized.

Note: Sensitometric and Diffuse RMS Granularity curves are produced on different equipment.

A slight variation in curve shape may be noticed.
