Process Techniques

The terms "skip bleach," "bleach bypass," "ENR," etc., refer to a number of related proprietary processing techniques currently being offered by some motion picture laboratories as a means of increasing contrast, darkening shadows and reducing the color saturation of images.

Push/Pull Processing

Eastman Kodak recommends a controlled ECN-2 process for the optimum performance of all of its color negative films. However, it is recognized that creative control and/or physical limitations may dictate exposing film under less than ideal conditions (i.e. normal exposure). This may necessitate the use of push / pull chemical processing.

Turbulation Guide

Streakiness is typically found in motion picture photography in scenes having large areas of static uniform density such as skies, sand and interior/exterior walls. Our goal here is to provide the framework for problem-solving.

Controlling Biological Growth (Slimes)

Biological growth (slimes) may be controlled using solutions. Either Proxel GXL or Spectrus NX106 is recommended for use in the final rinse of Process ECN-2. Some cost and amount differences exist, so users should make decisions based on availability and economics.

Shoreline Effects

A lot of work on shoreline drying was performed in 1973-74 when ECN-2 came along and a manufacturer of processing machines took our specifications at face value and designed a machine with only 3 minutes of drying time with impingement drying.

Darkroom Lighting Basics

By choosing the proper type of illuminant and carefully controlling the light it emits, darkroom illumination can be optimized for operator safety, comfort, and efficiency, while having minimal effect on the unprocessed film.
