COLOR NEGATIVE FILM

KODAK PROFESSIONAL PORTRA

160NC, 160VC, 400NC, 400VC,

400UC, and 800 Films

KODAK PROFESSIONAL PORTRA Films offer

photographers both variety and consistency. You have your

choice of speed, color saturation, and format for virtually any

shooting situation. PORTRA Films deliver beautifully

matched final prints across speeds and formats: 35 mm, 120,

220, and sheet formats; NC (natural color), VC (vivid color),

and UC (ultra color); 100T, 160, 400 and 800 speeds. The

PORTRA Film family yields consistently rich and detailed

negatives with a neutrally balanced tone scale from shadows

to highlights. An emulsion overcoat and scanner friendly

design make PORTRA Films the perfect choice for

photographers and labs who scan negatives.

KODAK PROFESSIONAL PORTRA 160NC Film

features natural colors and medium speed. Use 160NC Film

for smooth, natural flesh tones in controlled lighting

situations.

KODAK PROFESSIONAL PORTRA 160VC Film

features vivid colors and medium speed. Use 160VC Film

for rich, enhanced colors in controlled lighting situations.

KODAK PROFESSIONAL PORTRA 400NC Film

features natural colors and high speed. Use 400NC Film for

smooth, natural flesh tones in low light or on-camera flash

situations.

KODAK PROFESSIONAL PORTRA 400VC Film

features vivid colors and high speed. Use 400VC Film for

enhanced colors in low light or on-camera flash situations.

KODAK PROFESSIONAL PORTRA 400UC Film

features very vivid ("ultra") colors and high speed. Use

400UC Film for the highest color saturation in low light or

on-camera flash situations.

KODAK PROFESSIONAL PORTRA 800 Film

features the highest film speed with neutral flesh-tone

reproduction, tight grain, and medium color saturation. Use

PORTRA 800 Film when using long lenses, shooting action,

or shooting in low light.

KODAK PROFESSIONAL PORTRA 100T Film

delivers color accuracy under tungsten illumination (3200K)

and allows long exposure times with minimum effect on

color balance and contrast.

STORAGE AND HANDLING

Store unexposed film at 21°C (70°F) or lower in the original

sealed package. For extended periods, store film at

13°C(55°F) to preserve consistency.

To avoid moisture condensation on film that has been

refrigerated, allow the film to warm up to room temperature

before opening the package. Typical warm-up times are

given in the table below.

Load and unload roll-film cameras in subdued light. Total

darkness is required when you load and unload sheet film

holders.

Process film as soon as possible after exposure. Protect

negatives from strong light, and store them in a cool, dry

place. For long-term storage, keep negatives at a temperature

between 2°C (35°F) and 13°C (55°F) and at a relative

humidity between 30 and 35 percent.

Note: High speed films, such as PORTRA 800 Film, are

sensitive to environmental radiation. Expose and process this

film promptly. As exposure to radiation is cumulative, you

may want to request visual inspection of PORTRA 800 film

at airport and other security x-ray inspection stations.

DARKROOM RECOMMENDATIONS

Do not use a safelight. Handle unprocessed film in total

darkness.

EXPOSURE

Film Speed

Use the speed numbers in the tables below with cameras or

meters marked for ISO, ASA, or DIN speeds or exposure

indexes (EIs). Do not change the film-speed setting when

metering through a filter. Metering through filters may affect

light meter accuracy; see your meter or camera manual for

specific information. For critical work, make a series of test

exposures.

*

For best results without special printing.

Note: The latitude of PORTRA 160NC and 160VC Films

allows you to use 100-speed proofing products for test

exposures.

Daylight

Use the exposures in the table below for average frontlit

subjects from 2 hours after sunrise to 2 hours before sunset.

*

Use f/5.6 for backlit close-up subjects.

†

Use f/8 for backlit close-up subjects.

Use the appropriate guide number in the table below as

starting-point recommendations for your equipment. Select

the unit output closest to the number given by your flash

manufacturer. Then find the guide number for feet or metres.

To determine the lens opening, divide the guide number by

the flash-to-subject distance. If negatives are consistently too

dense (overexposed), use a higher guide number; if they are

too thin (underexposed), use a lower number.

Fluorescent and High-Intensity Discharge

Lamps

Use the color-compensating filters and exposure adjustments

in the tables below as starting points to expose

PORTRA Films under fluorescent or high-intensity discharge

lamps. For critical applications, make a series of test

exposures under your actual conditions.

To avoid the brightness and color variations that occur

during a single alternating-current cycle, use exposure

times of 1⁄60 second or longer with fluorescent lamps; with

high-intensity discharge lamps, use exposure times of

1⁄125 second or longer.

*

CCT = Correlated Color Temperature. Phosphor emission emulates the color temperature of a continuous spectrum lamp, such as tungsten.

CCT = Correlated Color Temperature. Phosphor emission emulates the color temperature of a continuous spectrum lamp, such as tungsten.

Adjustments for Long and Short Exposures

No filter correction or exposure compensation is required for PORTRA 160NC, 160VC, 400NC, PORTRA 400VC, or PORTRA

400UC Films for exposures from 1⁄10,000 second to 10 seconds. For PORTRA 800 Film, no adjustments are required for exposures

from 1⁄10,000 second to 1 second. For critical applications with longer exposure times, make tests under your conditions.

JUDGING NEGATIVE EXPOSURES

You can check the exposure level with a suitable electronic

densitometer equipped with a filter such as a KODAK

WRATTEN Gelatin Filter No. 92 or the red filter for

Status M densitometry. Depending on the subject and the

light source used for exposure, a normally exposed and

processed color negative measured through the red filter

should have the approximate densities listed below.

Because of the extreme range in skin color, use these red

density values for a normally lit forehead only as a guide. For

best results, use a KODAK Gray Card (gray side).

SCANNING NEGATIVES

You can easily scan PROFESSIONAL PORTRA Film

negatives with a variety of linear-array-CCD,

area-array-CCD, and PMT film scanners. You can scan

negatives on desktop scanners as well as high-end drum

scanners.

Because no standards exist to define the colored filter sets

that film scanners use to capture the red, green, and blue

information of the film image, each manufacturer’s scanner

has its own characteristic output. The output depends on the

scanner’s sensitivity to the dyes in the film. This sensitivity

is determined by the spectral distribution of the colored filter

sets and/or the spectral sensitivity of the

charge-coupled-device (CCD). In addition to these spectral

specifications, scanner output depends on the look-up tables

or matrices that the scanner uses to output information for

CRT monitors, transmission, etc. These tables or matrices

are part of either “plug-in” programs used with specific

software packages designed for image manipulation,

updateable ROMs included with the equipment, or fixed

algorithms for calibrating and balancing, similar to those

used in photographic color printing equipment.

The generic “color negative film” channel designation

available with scanner software is only a starting point. You

can adjust the final color balance and the scene-dependent

contrast and brightness of an image by using the scanner’s

controls during pre-scan, or by using an image-manipulation

software program or workstation after acquisition. Some

scanners allow you to use “plug-in” programs to customize

scanner setups.

IMAGE STRUCTURE

Print Grain Index

The Print Grain Index number refers to a method of defining

graininess in a print made with diffuse-printing illumination.

It replaces rms granularity and has a different scale which

cannot be compared to rms granularity.

•The method uses a uniform perceptual scale, with a

change of four units equaling a just noticeable

difference in graininess to 90 percent of observers.

•A Print Grain Index rating of 25 on the scale represents

the approximate visual threshold for graininess. A

higher number indicates an increase in the amount of

graininess observed.

•The standardized inspection (print-to-viewer) distance

for all print sizes is 14 inches, the typical viewing

distance for a 4 x 6-inch print.

•In practice, larger prints will likely be viewed from

distances greater than 14 inches, which reduces

apparent graininess.

•Print Grain Index numbers may not represent graininess

observed from more specular printing illuminants, such

as condenser enlargers.
