Abstract
The contrast of Kodak Ektaspeed decreased sharply when developed at the test temperatures above 22°C during manual processing with GBX solutions. Ultraspeed did not exhibit this effect. During automatic processing, neither film suffered loss of contrast at the test temperatures higher than 28.3°C. Both films showed wide latitude through the full range of time variations in both processing methods.Keywords
