Description

KODAK PROFESSIONAL TRI-X 320 and 400 Films are high-speed panchromatic films that are 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 400 Film (400TX) is available in120 and 135 sizes and 35 and 70 mm long rolls. You can retouch the 120-size film on the emulsion side. TRI-X 400 Film is recommended for push-processing applications.

TRI-X 320 Films (320TXP) feature excellent 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.

One TRI-X 320 Film (320TXP) is available in 120 and 220 sizes on a 3.9-mil acetate base, the other is available in sheets on a 7-mil ESTAR Thick Base. You can retouch these films on the emulsion or base side.

Sizes Available

Catalog numbers and packaging may differ from country to country. See your dealer who supplies KODAK PROFESSIONAL Products.

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 24°C (75°F) or lower in the original sealed 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, see KODAK Publication No. E-30, Storage and Care of KODAK Films and Papers—Before and After Processing.

Exposure

Daylight

Use the exposures in the table below for average front-lit subjects from 2 hours after sunrise to 2 hours before sunset.

Exposure and Development Adjustments for Long and Short Exposures

At the exposure times in the table below, compensate for the reciprocity characteristics of this film by increasing exposure and adjusting the development as shown.

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

Filter Corrections

Multiply the normal exposure time by the filter factor.

Darkroom Recommendations

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 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 No. K-4, How Safe Is Your Safelight?

Processing

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: Tank development times shorter than 5 minutes may produce unsatisfactory uniformity.

Manual Processing

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.

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

NR = Not Recommended.

Tray and Large-Tank Processing —Sheets

Provide continuous agitation; rotate the sheets 90 degrees as you interleave them. Prewetting sheet film may improve tray process uniformity.

Rotary-Tube Processing

Follow the agitation recommendations for your processor. The design of the machine and the agitation will significantly affect the development time required to obtain optimum contrast. The times given below are starting-point recommendations. Make tests to determine if results are acceptable for your needs.

Final Steps

65 to 75°F (18 to 24°C).

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 these films' exposure latitude, you can underexpose by one stop and use normal processing times. Prints will show a slight loss in shadow detail.

You can underexpose by two stops 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 TRI-X 400 Film / 400TX by three stops if you increase development time by push processing. 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.

NR = Not Recommended.

NR = Not Recommended.

Machine Processing

Roller-Transport Processors

KODAK VERSAMAT Film Processors

You can process these films in roller-transport processors, such as the KODAK VERSAMAT Film Processor, Model 5, 11, or 411, with KODAK DURAFLO RT Developer Starter, KODAK DURAFLO RT Developer Replenisher, and KODAK Rapid Fixer.

The recommended machine speeds for processing KODAK PROFESSIONAL TRI-X 320 and 400 Films are as follows:

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.

Processing Conditions for Other Roller-Transport Processors

Adjust the machine speed so that the development time for normally exposed film is approximately:

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.

Replenishment Rates

Developer—Because most film loads will consist of a variety of film types, use an average replenishment rate of 0.20 mL per square inch of film processed.

Fixer—Use 0.55 mL per square inch.

Push Processing: Roller Transport Processors

To process pushed TRI-X 320 or 400 Film in a machine with DURAFLO RT Developer (working solution), use a normal machine process with the machine speed shown in the appropriate table below.

Large Tank Rack-and-Tank Processors

The development times for large-tank rack-and-tank processors are based on a machine speed that transfers the film every 2 minutes. The times given below are starting-point recommendations for T-MAX RS Developer and Replenisher and XTOL Developer. Make tests to determine if results are acceptable for your needs.

Replenishment Rates

T-MAX RS Developer and Replenisher—Add 45 mL (1.5 ounces) of replenisher solution for each 135-36 or 120 roll or 8 x 10-inch sheet of film processed. Stir or recirculate the solution after each addition of replenisher solution.

Note: Do not use T-MAX RS Developer and Replenisher to replenish T-MAX Developer. They are not designed to work together.

XTOL Developer—Add 70 mL (2.4 ounces) of replenisher solution for each 135-36 or 120 roll or 8 x 10-inch sheet of film processed. Stir or recirculate the solution after each addition of replenisher solution.

Retouching

You can retouch KODAK PROFESSIONAL TRI-X 400 Film (135 and 120 sizes) on the emulsion side. You can retouch KODAK PROFESSIONAL TRI-X 320 Film (120, 220 and sheet sizes) by applying liquid dyes to the base or emulsion side. You can also use retouching pencil on the base side after applying KODAK Retouching Fluid.

Compared to KODAK TRI-X Pan and KODAK TRI-X Pan Professional Film, the newer TRI-X 400 and 320 Films may have a slightly different retouching "feel".

Image Structure

The following information was generated using the old versions of these films. Granularity testing of old and new films in several other developers suggests this information should also be valid for the new versions.The data in this section is based on development in KODAK HC-110 Developer (Dilution B), 68°F  (20°C).
