to highlights. An emulsion overcoat and scanner friendly
design make PORTRA Films the perfect choice for
photographers and labs who scan negatives.

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.

50-sheet box 3 2 2
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.

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.
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.

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, PORTRA 400VC, or PORTRA

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.
