DEVELOPMENT TIME (seconds)

The above chart can be used to determine other development time/temperature combinations that provide equivalent photographic quality. Temperatures between 90 and 100°F (32 and 37.8°C) are optimum for total system performance.

Notice: While the data presented are typical of production coatings, they do not represent standards which must be met by Eastman Kodak Company. Varying storage, exposure, and processing conditions will affect results. The company reserves the right to change and improve the product characteristics at any time.

After-Process Information

Keeping

This film is suitable for archival keeping when processed as recommended. However, due to possible variations in conditions, it is recommended that users establish their own compliance with existing archival-keeping requirements as outlined in pertinent standard ANSI/NAPM IT9.1-1996, ISO 10602 - 1995, and in Kodak Booklet D-31. This film is within thiosulfate limits for microfilm, when processed according to manufacturer’s recommendations.
