6 KODAK PROFESSIONAL Technical Pan Film • P-255
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.

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.
Processing with TECHNIDOL Liquid Developer in a
Small Tank: The following procedure may vary from the
instructions provided with your tank, but you must follow it
to obtain good results.
Develop roll film for the amount of time in the table below,
according to the developer temperature you choose.
1. Fill the tank with developer adjusted to one of the
temperatures in the table.
2. In total darkness, drop the loaded reels into the tank of
solution and attach the top to the tank.
3. Firmly tap the bottom of the tank on the top of the work
surface to dislodge any air bubbles. (You can then turn
on the room lights.)
4. Provide immediate agitation by shaking the tank
vigorously up and down 10 to 12 times for 2 seconds.
Do not rotate the tank.
Liquid Developer Agitation Technique
5. Let the tank sit for 30 seconds, and then start the next
