BLACK-AND-WHITE REVERSAL FILM

KODAK TRI-X Reversal Film 7266

We are committed to black & white film—improvements to

our family of reversal films prove it. New KODAK TRI-X

Reversal Film 7266 offers finer grain and increased

sharpness, and includes EASTMAN KEYKODE Numbers

for easy cross-reference of shots in minutes, not hours.

Reduced static support allows for a cleaner image

throughout the filmmaking process. And because our new

films do not require processing in a bleach containing

heavy metals, they are easier on the environment. Our

improved films provide the rich blacks and high contrast

you have come to expect from KODAK Black & White

reversal films.

KODAK TRI-X Reversal Film 7266 (16 mm) is a

high-speed, panchromatic black-and-white film with an

antihalation undercoat that makes it suitable for general

interior photography with artificial light. It can also be used

in daylight and is particularly useful for sports pictures

taken at regular speed or slow motion in weak light

(overcast sky or late in the day). This film is characterized

by excellent tonal gradation and sharpness.

When processed as a reversal film, the resulting positive

can be used for projection or for duplication. If processed

as a negative material by conventional methods, the film

will yield satisfactory results, although there will be some

loss in speed and an increase in granularity.

BASE

KODAK TRI-X Reversal Film 7266 has a grey acetate safety

base with an additional anti-halation undercoat. The back

side of the base contains an anti-static layer with a

carnauba wax lubricant.

DARKROOM RECOMMENDATIONS

Reversal Processing

All processing operations should be carried out in total

darkness until the bleaching step has been completed. If

necessary, the film can be examined (for a few seconds

only) after development is 50 percent complete. Use a

KODAK 3 Safelight Filter / dark green, with a 15-watt bulb,

no closer to the film than 1.2 metres (4 feet). Following

bleaching, normal room lighting can be used.

Negative Processing

No safelight is recommended until after the stop bath.

Unprocessed films must be handled in total darkness.

STORAGE

Store unexposed film at 13°C (55°F) or lower. For extended

storage, store at -18°C (0°F) or lower. Process exposed film

promptly. Store processed film according to the

recommendations in ANSI/PIMA IT9.11-1998: for

medium-term storage (minimum of ten years), store at

10°C (50°F) or lower at a relative humidity of 20 to

30 percent; for extended-term storage (for preservation of

material having permanent value), store at 2°C (35°F) or

lower at a relative humidity of 20 to 30 percent. For active

use, store at 25°C (77°F) or lower, at a relative humidity of

50 +/- 5 percent. This relates to optimized film handling

rather than preservation; static, dust-attraction and

curl-related problems are generally minimized at the

higher relative humidity. After usage, the film should be

returned to the appropriate medium- or long-term storage

conditions as soon as possible.

For more information about medium- and long-term

storage, see ANSI/PIMA IT9.11-1998, SMPTE RP131-2002,

and KODAK Publications No. H-845, The Essential

Reference Guide for Filmmakers.

EXPOSURE INDEXES

Tungsten (3200K) - 160 Daylight - 200

Use these indexes with incident- or reflected-light

exposure meters and cameras marked for ISO or ASA

speeds or exposure indexes. These indexes apply for meter

readings of average subjects made from the camera

position or for readings made from a gray card of

18-percent reflectance held close to and in front of the

subject. For unusually light- or dark-colored subjects,

decrease or increase the exposure indicated by the meter

accordingly.

EXPOSURE TABLE - TUNGSTEN LIGHT

At 24 frames per second (fps), 170-degree shutter

opening:

At 18 frames per second, use 3/4 of the footcandles (fc) shown. When the

film is used as a negative material, the values specified should be doubled.

Lighting Contrast -

The recommended ratio of key-light-plus-fill-light to fill

light is 2:1 or 3:1. However, you may use 4:1 or greater

when a particular look is desired.

FILTER FACTORS

For use in bright sunlight to reduce the exposure without modifying color

rendering or depth of field. This filter which has a neutral density of 0.90

provides a reduction in exposure equivalent of 3 full stops.

RECIPROCITY CHARACTERISTICS

You do not need to make any exposure adjustments for

exposure times from 1/1,000 to 1 second. If your exposure

is in the 1/10,000 second range, it is recommended that

you increase your exposure by

⁄

stop.

1.Super 8 automatic cameras will expose the film at ASA 160 due to the ANSI

standard cartridge.

REVERSAL PROCESSING

KODAK B&W Reversal Process

This film should be processed with KODAK B&W

Reversal Process Kit Chemicals or with solutions prepared

according to the formulas presented in KODAK

Publication No.H-24.15, Manual for Processing KODAK

Motion Picture Films, Module 15.

Note: KODAK B&W Reversal First Developer and

Replenisher (D-94A) and KODAK B&W Reversal Bleach

and Replenisher (R-10) should be used with this film.

The recommended starting points for processing times

and temperatures are shown in the table below. Actual

processing times may differ from the ones shown because

of machine design variables, such as film transport speed,

degree of solution agitation, amount of solution carry-over,

etc.

Notice: Observe precautionary information on product labels and on the

Material Safety Data Sheets.

IDENTIFICATION

After processing, the product code numbers 7266,

emulsion and roll number identification, emulsion letter

designator ED, and KEYKODE number are visible along the

length of the film.

AVAILABLE ROLL LENGTHS

For information on film roll lengths, check Kodak's Motion

Picture Films product catalog or see a Kodak sales

representative in your country.
