Kodak 2393 Sensitometric Curves, SPECTRAL-SENSITIVITY Curves, Diffuse RMS Granularity Curves

SENSITOMETRIC CURVES

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.

SPECTRAL-SENSITIVITY CURVES

These curves depict the sensitivity of this film to the spectrum of light. They are useful for adjusting optical printers and film recorders and for determining, modifying, and optimizing exposure.

The spectral sensitivity of VISION Premier Color Print Film / 2393 more closely matches EASTMAN EXR Color Intermediate Film 5244, 2244. This gives a better match between direct prints and prints from a duplicate negative produced on EASTMAN EXR Color Intermediate Film.

DIFFUSE RMS GRANULARITY CURVES

The emulsion granularity of this film is similar to Film 2386 / E / 3386 / E. VISION Premier Color Print

Film / 2393 does have a higher level of very small matte. The matte particles may be visible at extremely close viewing distance to the screen, especially in clear (D-min) areas of the print.

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.
