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 characteristic 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. Note: This curve represents granularity based on modified measuring techniques.

2.NOTE: Sensitometric and Diffuse RMS Granularity curves are

produced on different equipment. A slight variation in curve shape may

be noticed.

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.
