TECHNICAL DATA / BLACK-AND-WHITE FILM
KODAK PROFESSIONAL Technical
Pan Film
KODAK PROFESSIONAL Technical Pan Film is Kodak’s
slowest and finest-grained black-and-white film for pictorial
photography (when developed in KODAK TECHNIDOL
Liquid Developer). It is a variable-contrast panchromatic
film with extended red sensitivity; because of its extended
red sensitivity, it yields prints with a gray-tone rendering
slightly different from that produced by other panchromatic
films. (This is most noticeable in portraits, in which it
suppresses blemishes.)
Use this film for pictorial, scientific, technical, and
reversal-processing applications. It is an excellent choice for
making big enlargements or murals.
APPLICATIONS
You can vary the contrast of KODAK PROFESSIONAL
Technical Pan Film by modifying development. The wide
range of contrast levels, along with the spectral sensitization
and combination of speed and image-structure properties,
makes this film unusually versatile and suitable for many
applications:
• Pictorial photography
• Photomicrography
• Microphotography (Microfilming)
• Solar photography
• Photographing electrophoretic gels
—NOTICE—
Discontinuance of
KODAK PROFESSIONAL Technical Pan Film
KODAK PROFESSIONAL Technical Pan Film is being
discontinued due to steadily declining demand over the recent
years. Changes in product components and our manufacturing
processes make it impractical to continue to support this
product at its current low levels.
The last Tech Pan coating was several years ago. Since that
time, the old coating room has been shut down, the gels used
in the product formulation have become obsolete, and we no
longer manufacture the ESTAR support on which the 35 mm
product was coated. There would be considerable cost to
recreate the product, with no guarantee that it would look and
act the same as the Tech Pan Film of old.
Technical Pan Film will continue to be available until the
existing inventory has been depleted.
While there is no direct replacement for Tech Pan Film, you
may find KODAK PROFESSIONAL T-MAX 100 Film in
combination with specific B&W Developers to be a viable
alternative for some applications.
• Laser recording
• Other applications such as slide making, copying, and
microfilming that require high or moderately high
contrast combined with fine grain and high resolving
power

KODAK PROFESSIONAL Technical Pan Film 2415
KODAK PROFESSIONAL Technical Pan 4415
KODAK PROFESSIONAL Technical Pan Film 6415
Because 2415 Film has a thinner base than conventional
35 mm picture-taking films, 150-foot rolls finished to Sp 442
will fit in bulk-film loaders designed to accept 100-foot rolls.
Other sizes are available on a special-order basis, subject
to manufacturing limitations and current minimum-order
requirements. Minimum-order quantities for special-order
sizes are generally 750 square feet (70 square metres) of
film.
