October 2006 • E-190

This publication has been superceded by Kodak

publication E-4040, KODAK PROFESSIONAL PORTRA

160NC, 160VC, 400NC, 400VC, and 800 Films.

This change reflects improvements made to the PORTRA Film
family in September 2006. A new generation of KODAK
PROFESSIONAL PORTRA 160- and 400-speed Films have
been reengineered to deliver significantly finer grain while
maintaining superb skin tone reproduction. These new
PORTRA Films will be available worldwide on a stock-turnover
basis beginning in Q4 2006. For more information, please

--NOTICE--

.

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) and VC (vivid
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 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.

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.

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.

Adjustments for Long and Short Exposures

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

Electronic Flash

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.

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.
