It may be difficult to use the table to estimate the adjusted times for calculated exposure times between 1 and 100 seconds. The graphs below will help you find the adjusted times for calculated exposure times between those given in the table.

DARKROOM RECOMMENDATIONS

Use a safelight equipped with a KODAK 1A Safelight Filter (light red) with a 15-watt bulb. Keep the safelight at least

4 feet (1.2 metres) from the film. Run tests to determine that safelight use gives acceptable results for your application.

For information on safelight testing, see KODAK Publication K-4, How Safe Is Your Safelight?

PROCESSING

Small-Tank Processing (8- or 16-ounce tank)

Develop EKTAGRAPHIC HC Slide Film at 68°F (20°C) in a small tank. We recommend using KODAK Developer D-11 or KODAK PROFESSIONAL KODALITH Super RT Developer for processing this film. KODAK Developer D-11 provides slightly lower contrast, more exposure latitude, longer solution life, and high projection contrast. It also produces faster film speed or short camera exposures.

Note: For even development of the entire roll, first fill the tank with developer. Then, using the above safelight handling instructions, drop the loaded film reel into the developer and attach the top to the tank. Firmly tap the tank on the top of the work surface to dislodge any air bubbles. Agitate for 5 seconds every 30 seconds throughout development. You can do the remaining operation in room light.
