Kodak P-255 manual Processing, Liquid Developer Agitation Technique

PROCESSING

Handle unprocessed film in total darkness. After development is half complete, you can use a suitable a safelight lamp equipped with a KODAK 3 Safelight Filter (dark green) and a 15-watt bulb for a few seconds. Keep the safelight at least 4 feet (1.2 metres) from the film.

When you use these films for pictorial applications, you must select a film-and-developer combination carefully. With 35 mm Technical Pan Film, use TECHNIDOL Liquid Developer. With Technical Pan Film / 4415 and 6415 (sheets and 120 size), use only TECHNIDOL Liquid Developer. Observe the precautionary information on the developer packaging.

KODAK TECHNIDOL Liquid Developer Small-Tank Processing (rolls)

You can process roll film in small 8- or 16-ounce stainless-steel or 10- or 20-ounce plastic tanks with spiral reels using the following instructions. With some spiral reels, the 35 mm film may be susceptible to nonuniform processing effects if agitation is not carefully controlled. Pouring the developer on dry film through the light trap in the tank top can also produce nonuniformity. To avoid processing problems, pour the developer into the tank before you insert the loaded reel, and follow the agitation recommendations below.

Preparing a Working Solution: Mix your liquid developer according to the instructions packaged with the developer. Use water at 68 to 86°F (20 to 30°C).

To process one roll of 135-36 film, make 8 fl oz (237 mL) of developer solution. Stir until the solution is completely mixed. To process one 120-size roll or two 135-36 rolls of film in the same process, prepare one pint (16 fl oz [473 mL]) of developer.

You can reuse the developer if you increase the development time of the second process by 1 minute. Store the developer in an air-tight bottle, and use it within a week.
