Description

Medium-contrast, medium-speed, daylight (5500°K), (electronic
flash) balanced color print film with extended dynamic range.

Key Applications

• Document or passport photography

• Professional photography (test shots/proofing)

• Close-up photography

• Image Transfer

• Emulsion Transfer

ILOP

• Electronic imaging print output

Compatible Hardware

• Cameras or instruments with CB-103 Back or OEM CB-100

Back (these holders are supplied by medium format camera
manufacturers such as Mamiya, Hasselblad and Konica)

• Polaroid Model 405 Film Holder

Special Treatment

None

Reciprocity Performance

The reciprocity characteristics of the film cause a color shift
towards blue-cyan when the exposure time is increased and a
color shift towards red-yellow when the exposure is decreased.

The film is balanced for average daylight (5500°K) at
second (as well as for electronic flash units). Recommended
filtration at other exposure times and with other illuminants is
indicated on information packaged with the film.

Caution

This film uses a small amount of caustic paste. If any paste appears, avoid contact with skin, eyes and mouth
and keep away from children and animals. If you get some paste on your skin, wipe it off immediately, then
wash with water to avoid an alkali burn. If eye contact occurs, quickly wash the area with plenty of water and
see a doctor. Keep discarded materials away from children, animals, clothing and furniture.

D-Max: The density value for the
film’s darkest black.

D-Min: The lowest density value
that a film exhibits. In prints, the
whiteness of the brightest highlight,
relative to the unprocessed print.

Slope: The positive ratio of the log
E increments of the straight line
region of the curve, as determined
by the 1/4-3/4 increment method.
The slope of an H&D curve
indicates the overall contrast of a
film: low contrast slopes less than

1.10; medium contrast slopes from

1.10 to 1.70; high contrast slopes
greater than 1.70.

Reciprocity law failure

A wide range of shutter speeds can be used without loss of film speed.
For longer exposure times, some exposure compensation is suggested.

Wavelength (nm)

Reciprocity: The ability of the film to respond in a constant manner
to a constant exposure (light intensity x time). Reciprocity failure
occurs during very long or very short exposures, requiring the
photographer to increase exposure.

Spectral Sensitivity: Shows the equivalent energy needed at each
wavelength in order to activate the emulsion so that it produces a
neutral density of .75.
