TECHNICAL DATA / BLACK-AND-WHITE FILM
KODAK PROFESSIONAL PLUS-X
125 Film / 125PX
KODAK PROFESSIONAL PLUS-X 125 Film is a
—NOTICE—
medium-speed, continuous-tone panchromatic film that is a
good choice for general-purpose outdoor or studio
photography. It features extremely fine grain and excellent
sharpness.
KODAK PROFESSIONAL PLUS-X Film is available in
135 size and 35 mm long rolls on a 5-mil gray acetate base,
and in 120 and 220 size on a 3.6-mil acetate base. The 120
and 220 sizes have a retouching surface on the emulsion side.
To reflect our enduring commitment to black-and-white
photography, black-and-white film production will take place in
an even more advanced film-coating facility. New technology
applied to these superior, time-tested emulsions will result in
slightly different processing times for the film family. But the
same great films—those you've known and trusted for years—
will still deliver the same breathtaking results.
Use the packaging examples below to determine which film
you have, then refer to the corresponding publication for
development times.

MANUAL PROCESSING
DARKROOM RECOMMENDATIONS
Handle unprocessed film in total darkness.
Small-Tank Processing (8- or 16-ounce tank)
With small single- or double-reel tanks, 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. Provide initial agitation of 5 to 7 inversion cycles in
5 seconds; i.e., extend your arm and vigorously twist your
wrist 180 degrees.
Using a safelight will affect your results. If absolutely
necessary, after development is half complete, you can use a
safelight equipped with a KODAK 3 Safelight Filter (dark
green) with a 15-watt bulb for a few seconds. 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.
Then repeat this agitation procedure at 30-second
intervals for the rest of the development time.
For information on safelight testing, see KODAK
Publication No. K-4, How Safe Is Your Safelight?
Large-Tank Processing (1/2- to 3 1/2-gallon
tank)—Rolls and Sheets
PROCESSING
Agitate continuously for the first 15 to 30 seconds by raising
and lowering the basket, rack, or spindle 1/2-inch. Do not
agitate the basket, rack, or spindle for the remainder of the
first minute. Then agitate once per minute by lifting the
basket, rack, or spindle out of the developer, tilting it
approximately 30 degrees, draining it for 5 to 10 seconds,
and reimmersing it. Alternate the direction of tilting the
basket, rack, or spindle.
These starting-point recommendations are intended to
produce negatives with a contrast appropriate for printing
with a diffusion enlarger. To print negatives with a condenser
enlarger, you may need to adjust the contrast by reducing your
development time. Tank development times shorter than
5 minutes may produce unsatisfactory uniformity.

PUSH PROCESSING
Push processing allows you to expose the film at higher
film-speed numbers for conditions such as low-level light,
stop action, or existing light. However, there will be a loss
of shadow detail and an increase in graininess.
Because of the film's exposure latitude, you can
underexpose by one stop at EI 250 and use normal
processing times. Prints will show a slight loss in shadow
detail.
You can underexpose by two stops at EI 500 if you
increase development time by push processing. Prints will
show an increase in contrast and graininess with further loss
of shadow detail. However, results should be acceptable for
many applications. Expose a test roll to determine the film
speed that gives the best results for your application.
You can underexpose the film by three stops (EI 1000)
when you use 3-stop push processing in KODAK XTOL
Developer. Prints will show an increase in contrast and
graininess, and an additional loss of shadow detail.
However, results should be acceptable for some
applications. Expose some test rolls to determine the film
speed that gives the best results for your application.

You may need to use higher dryer temperatures (135 to
140°F [57 to 60°C]) to dry several sheet films processed in
succession. If you are processing only roll films, a lower
temperature will be adequate.

Adjust the machine speed so that the development time for
normally exposed film is approximately 60 seconds. The
development time is measured from the time the film enters
the developer to the time it enters the fixer. Differences in
machine design that affect agitation and crossover times
from one tank to the next may require development-time
adjustments.
