DESCRIPTION

KODAK TRI-X Pan Film / TX
KODAK TRI-X Pan Professional / TXP and TXT

KODAK TRI-X Pan Film is a high-speed (ISO 400/27°) panchromatic film that is a good choice for photographing dimly lighted subjects or fast action, for photographing subjects that require good depth of field and fast shutter speeds, and for extending the distance range for flash pictures. TRI-X Pan Film (TX ) is available in120 and 135sizes and 35 and 70 mm long rolls. You can retouch the 120-size film on the emulsion side. TRI-X Pan Film is recommended for push-processing applications.

Both TRI-X Pan Professional Films have an ISO speed of 320/26°, and feature e x cellent tone gradation and brilliant highlights. They are especially well suited to low-flare interior lighting or flash illumination. They are also useful for portraiture with low-contrast backlighting outdoors.

TRI-X Pan Professional Film (TXP) is available in 120 and 220sizes on a 3.6-mil acetate base. You can retouch this film on the emulsion or base side.

TRI-X Pan Professional Film (TXT) is available in sheet sizes. You can retouch this film on the emulsion or base side.

FEATURES BENEFITS
Fine grain Good for producing high-quality images
Wide exposure latitude Rich tonality maintained with over exposure and underexposure
High sharpness Good for applications that require a moderate degree of enlargement
High resolving power Good rendition of detail

STORAGE AND HANDLING

Load and unload your camera in subdued light.

High temperatures or high humidity may produce unwanted quality changes. Store unexposed film at 75°F (24°C) or lower in the original package. Always store film (exposed or unexposed) in a cool, dry place. For best results, process film as soon as possible after exposure.

Protect processed film from strong light, and store it in a cool, dry place. For more information on storing negatives, see KODAK Publication No.E-30, Storage and Care of Photographic Materials--Before and After Processing.

DARKROOM RECOMMENDATIONS

Do not use a safelight. Handle unprocessed film in total darkness.

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 4feet (1.2metres) 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?

MANUAL PROCESSING

General Recommendations

Handle unprocessed film in total darkness.

The following starting-point recommendations are intended to produce a contrast Index of 0.56. Make tests to determine the best development time for your application.

Note: Development times shorter than 5 minutes may produce unsatisfactory uniformity.

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

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 5to7 inversion cycles in 5seconds; i.e., extend your arm and vigorously twist your wrist 180 degrees.

Then repeat this agitation procedure at 30-second intervals for the rest of the development time.

Large-Tank Processing ( 1/2 to 3 1/2-gallon tank)--Rolls and Sheets

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 5to 10seconds, and reimmersing it. Alternate the direction of tilting the basket, rack, or spindle.

PUSH PROCESSING for
KODAK TRI-X
PAN FILM / TX

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 EI800 and use normal processing times. Prints will show a slight loss in shadow detail.

You can underexpose by two stops at EI1600 if you increase development time by push processing. Prints will show an increase in contrast and graininess with additional loss of shadow detail. However, the results will be acceptable for many applications.

You can underexpose by three stops at EI3200 if you increase development time by push processing. Prints will show an increase in contrast and graininess with further loss of shadow detail. However, the results will be acceptable for many applications. We recommend exposing a test roll to determine the film speed that will give the best results for your application.

Following are starting-point recommendations to produce a contrast Index of0.72 (representative of a 2-stop push).
