Choosing Eastman Color Negative Film 5247 or Eastman Color High-Speed Negative Film 5294

Since the introduction of high-speed color negative films, the cinematographer is frequently faced with selecting between shooting medium-speed (EI-125) Eastman color negative film 5247 or high-speed (EI-400) Eastman color high-speed negative film 5294. As an aid in making this decision, several objective parameters are examined as a function of exposure. In addition, general guidelines are presented for choosing the most appropriate film for different exposing conditions.

Printing System Evaluation

The Printing Systems Evaluation (PSE) compares printer operations in terms of printer lights. The system relies on standard industrial practice, incorporating such parameters as lamp type, trims and tapes, filters, shutter angle, aperture, and film transport speed. The PSE can improve the efficiency of both additive and subtractive printers, and can also be used by printer and film manufacturers to design better equipment and new films.
