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.

See your dealer who supplies KODAK PROFESSIONAL  
Products.  
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.

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.)

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:

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.

Adjustments for Long and Short Exposures  
Compensate for the reciprocity characteristics of this film by  
increasing exposure and adjusting the development as  
shown.  
DARKROOM RECOMMENDATIONS  
Handle unprocessed film in total darkness. After  
development is half completed, you can use a KODAK  
3 Safelight Filter (dark green) in a suitable safelight lamp  
with a 15-watt bulb. Keep the safelight at least  
4 feet (1.2 metres) from the film.

SPECIFIC APPLICATIONS  
Pictorial Photography  
These films produce high-quality pictorial negatives when  
processed in KODAK TECHNIDOL Liquid Developer. (See  
“PROCESSING.”) Conventional developers generally  
produce contrast too high for normal pictorial photography.  
Process the film according to the instructions for KODAK  
TECHNIDOL Liquid Developer.  
In pictorial applications, the fine grain permits  
enlargements at magnifications of 25X or more with little  
perceptible grain. The extended red sensitivity has a  
haze-cutting effect in photographs of distant landscapes and  
in aerial shots.  
• Tungsten 200/24°—for incident-light readings or for  
reflected-light readings from a gray card (18-percent  
reflectance) at the copyboard.  
• Tungsten 40/17°—for reflected-light readings from a  
matte white card (90-percent reflectance) at the  
copyboard.  
Note: These values for reverse-text slides are based on  
development in KODAK DEKTOL Developer for 3 minutes  
at 68°F (20°C).  
The exposure index is based on the formula EI = 10/H,  
where H is the 1-second exposure in lux-seconds required to  
produce a density of 0.60 above minimum density with the  
indicated development.  
Use an exposure index of 25 for trial exposures.  
Copy Applications  
You can use these films for copying printed material, making  
reverse-text title slides, and copying continuous-tone  
photographs.  
Use two lamps. Place one on each side of the copy  
material so that each light strikes the material at about a  
45-degree angle. For originals larger than 16 x 20 inches  
(40 x 50 cm), you may need four lamps (two on each side)  
for uniform illumination. Determine the exposure with a  
meter.  
If you use a camera with a through-the-lens meter, take the  
reading from a gray card in the copy position. The meter  
could give you an incorrect reading from the copy itself,  
depending on the amount of text.  
If you do not use an exposure meter, try these starting  
points: With two No. 2 photolamps in matte-surface  
reflectors at about 4 feet (1.2 metres) from the copyboard,  
use 1/60 second at ƒ/8. With two No. 1 photolamps, increase  
the exposure by one stop.  
Copying Continuous-Tone Photographs: To copy  
continuous-tone photographs, use an exposure-index value  
to achieve a gamma value between 0.6 and 1.0, depending on  
the contrast of the original. For low-contrast originals, you  
can try KODAK HC-110 Developer (Dilution B) for  
6 minutes (EI 160); for higher-contrast originals, use  
KODAK TECHNIDOL Liquid Developer for 9 minutes  
(EI 25).  
Microphotography (Microfilming)  
The resolving power of Technical Pan Film allows  
microfilming of most documents at reductions of up to 20X,  
assuming that the copying lens is of high quality and is  
carefully focused. The film plane and the plane of the  
copyboard must be parallel to provide sharp focus over the  
whole image area. When you photograph black-and-white  
originals, use a green filter such as a KODAK WRATTEN  
Gelatin Filter No. 58 or 61. This will help suppress the  
chromatic aberrations found in most lenses that would be  
emphasized by the extended red sensitivity of the film.  
For optimum image quality, adjust the exposure to  
achieve a negative density of 1.20 in the areas that  
correspond to the white or light-colored areas of the original.  
Process the film to a gamma of 2.0 in KODAK HC-110  
Developer (Dilution D) for 8 minutes at 68° F (20°C)  
(EI 125).  
With meters marked for ISO (ASA/DIN) speeds or exposure  
indexes, use these film-speed values:  
Starting-Point Exposures for Copying Printed  
Materials: With meters marked for ISO (ASA/DIN) speeds  
or exposure indexes, use these film-speed values:  
• Tungsten 320/26°—for incident-light readings or for  
reflected-light readings from a gray card (18-percent  
reflectance) at the copyboard.  
• Tungsten 64/19°—for reflected-light readings from a  
matte white card (90-percent reflectance) at the  
copyboard.  
Photographing Electrophoretic Gels  
Electrophoretic gels are often photographed to produce  
prints for information storage, analysis, display, and  
publication. KODAK PROFESSIONAL Technical Pan  
Films yield high-quality black-and-white negatives from  
which you can make high-quality prints of these gels. Adjust  
exposure carefully to minimize the appearance of the gel  
background tint in the prints.  
Make tests to determine exposures for your lighting  
conditions. Develop the film for 4 minutes in KODAK  
HC-110 Developer (Dilution D) at 68°F (20°C) (EI 80).  
TECHNIDOL Liquid Developer may also work with your  
setup.  
Note: These values are based on small-tank development in  
KODAK Developer D-19 for 4 minutes at 68°F (20°C) with  
agitation at 30-second intervals.  
The exposure index is based on the formula EI = 36/H,  
where H is the 1-second exposure in lux-seconds required to  
produce a density of 1.20 above minimum density with the  
indicated development.

KODAK PROFESSIONAL Technical Pan Film P-255  
 
Photomicrography  
Astronomical Photography  
The low contrast of most microscopic subjects often requires  
a contrast-enhancing film-and-developer combination and  
(with stained specimens) a contrast-enhancing filter. For  
routine photomicrography of H and E-stained tissue, try a  
broad-band yellow-green filter (e.g., a KODAK WRATTEN  
Gelatin Filter No. 11) at a tungsten exposure index of 50,  
developed in HC-110 Developer (Dilution B) for 8 minutes  
at 68°F (20°C). Negatives should print easily and with good  
contrast on normal-contrast paper. (If negatives are too  
dense, use a higher exposure index; if too thin, use a lower  
one. If contrast is too low, increase the development time; if  
too high, decrease the time.)  
For phase-contrast and differential-contrast techniques,  
try a tungsten exposure index of 100, and develop in HC-110  
Developer (Dilution D) for 6 minutes at 68°F (20°C). (If  
necessary, adjust the exposure index or development as  
described above.) This method may also be suitable for  
banding techniques in chromosome photomicrography.  
When you want maximum contrast, as in older karyotyping  
methods, use a tungsten exposure index of about 125, and  
develop in Developer D-19 for 4 minutes at 68°F (20°C).  
(Because of the differing spectral sensitivities of microscope  
photocells and the special characteristics of Technical Pan  
Films, these exposure index recommendations cannot be  
exact.)  
The extended red sensitivity of Technical Pan Films makes  
them especially suited to solar photography at the H-alpha  
line (656 nm), and their reasonably uniform spectral  
sensitivity over the visible region of the spectrum makes them  
most useful for solar filtergrams. They are also useful for  
lunar and planetary photography. The extremely fine grain  
and high resolving power, coupled with high-contrast  
development (with Developer D-19, for example) permits  
reproduction of very fine detail on objects in the solar system.  
You can use these films for stellar photography, but first  
hypersensitize them with forming gas or silver nitrate to  
improve the film response with the long exposures required.  
(For information on hypersensitization of Technical Pan  
Films, see the American Astronomical Society  
Photo-Bulletin, Issue No. 24, 1980, No. 2.)  
Laser Photography  
The extended red sensitivity of these films makes them very  
useful in applications in which the exposing radiation is from  
helium-neon lasers (633 nm) or red-light-emitting diodes  
(typically 640 to 650 nm).  
For example, Technical Pan Films are frequently  
recommended for photographing holograms reconstructed  
with the helium-neon lasers. Since the range of scene  
brightnesses that can be recorded and reconstructed  
holographically is inherently great, it is sometimes  
appropriate to process the film to a low contrast (contrast  
index of 0.5 to 0.6). However, in holographic interferometry,  
processing the film to a contrast index of 1.5 or more will  
enhance the visibility of the interferometric fringe by  
increasing its modulation. Try HC-110 Developer  
(Dilution B).  
Metallographers can easily select development conditions  
from the characteristic curves shown in this pamphlet, based  
on the contrast index they have used successfully with other  
materials.  
Electron Micrography  
Use Technical Pan Film to record the output of the  
fiber-optic faceplate in transmission electron microscopes  
and to provide optimum contrast and resolution for  
biological specimens.  
Make tests to determine exposures for the accelerating  
voltage and magnification. Develop for 512 minutes in  
Developer D-19 (1:2) at 68°F (20°C) or for 4 minutes in  
Developer D-19 (full strength) at 68°F (20°C). For less  
contrast, process for 8 to 12 minutes in HC-110 Developer  
(Dilution B) at 68°F (20°C).  
In image-recording or plotting applications, you can  
control the film contrast during processing to convert the  
modulation range of the recorder to the density range you  
want on the film.

When you use these films for pictorial applications, you  
must select a film-and-developer combination carefully.  
With 35 mm Technical Pan Film, use TECHNIDOL Liquid

Small-Tank Processing (rolls)  
4. Provide immediate agitation by shaking the tank  
vigorously up and down 10 to 12 times for 2 seconds.  
Do not rotate the tank.  
You can process roll film in small 8- or 16-ounce  
stainless-steel or 10- or 20-ounce plastic tanks with spiral  
reels using the following instructions. With some spiral reels,  
the 35 mm film may be susceptible to nonuniform processing  
effects if agitation is not carefully controlled. Pouring the  
developer on dry film through the light trap in the tank top  
can also produce nonuniformity. To avoid processing  
problems, pour the developer into the tank before you insert  
the loaded reel, and follow the agitation recommendations  
below.  
Liquid Developer Agitation Technique  
Preparing a Working Solution: Mix your liquid developer  
according to the instructions packaged with the developer.  
Use water at 68 to 86°F (20 to 30°C).  
To process one roll of 135-36 film, make 8 fl oz (237 mL)  
of developer solution. Stir until the solution is completely  
mixed. To process one 120-size roll or two 135-36 rolls of  
film in the same process, prepare one pint (16 fl oz [473 mL])  
of developer.  
You can reuse the developer if you increase the  
development time of the second process by 1 minute. Store  
the developer in an air-tight bottle, and use it within a week.

sheet out every 5 seconds and placing it on top. Be sure  
to keep the film emulsion side up and to keep the stack  
immersed.  
4. After 212 minutes, locate the first sheet, remove it, and  
allow it to drain. Using the same code-notch orientation,  
quickly place the sheet in the developer and agitate for  
about 10 seconds. Move the remaining sheets to the  
developer one at a time, agitating each for 10 seconds.  
Be careful that they don’t scratch each other.

Rinse the film in KODAK Indicator Stop Bath or KODAK  
EKTAFLO Stop Bath for 15 to 30 seconds. Use running  
water for 30 seconds if you don’t use a stop bath.  
Fix the film with frequent agitation in KODAK Rapid Fixer  
for 112 to 3 minutes. Or use KODAK PROFESSIONAL  
Fixer or KODAFIX Solution for 2 to 4 minutes.  
Develop at 68°F (20°C) for 8 minutes. Be sure the developer  
is at 68°F (20°C). Agitate the film in the developer as you did  
in the presoak. However, increase the rate of the initial  
agitation by going through the stack of film four times in the  
first minute of development. After 1 minute, take the entire  
stack of film and turn it 180 degrees. Continue the agitation  
at the normal rate of going through the stack twice per  
minute for the rest of the development time. Continue  
rotating the film as follows:  
Wash the film in clean running water for 5 to 15 minutes.  
To save time and conserve water, use KODAK Hypo  
Clearing Agent. Rinse the fixed film in running water for  
15 seconds. Bathe the film in KODAK Hypo Clearing Agent  
for 1 to 2 minutes with agitation. Then wash the film for  
5 minutes in running water, providing at least one change of  
water during the 5 minutes.

Tray Processing (sheets)  
Mix 1 quart (32 fl oz [946]) of TECHNIDOL Liquid  
Developer at one-half the working strength you’d use for roll  
films. That is, use 2 packets of developer concentrate and add  
enough water at 68°F (20°C) to make 1 quart. Stir until the  
developer is completely mixed.  
You can develop the equivalent of twelve 4 x 5-inch  
sheets of film in this amount of solution. Do not reuse this  
solution for a second batch even if your first batch consisted  
of fewer than twelve sheets.

Other KODAK Developers  
To process these films in the other developers listed in the  
table Exposure- and Contrast-Index Values for Various  
Development Conditions or the Quick Reference Guide to  
Developers, follow the instructions for your tank.  
Before using any developer, make sure that the solution is  
free of small air bubbles. If bubbles adhere to the emulsion,  
they may cause small undeveloped clear spots on the film  
(dark spots on the print). Bubbles may form more easily if  
you mix cold and hot water. If bubbles do form, let the  
developer stand until they dissipate. Attaching an aerator to  
the water supply will help eliminate small bubbles.  
Develop to the contrast index for your application; see  
“Exposure” and the characteristic curves. The contrast index  
depends primarily on the developer, temperature, dilution,  
and processing technique. It is affected less by exposure time  
and normal product variability.

To produce a contrast index of about 1.4, start with a machine  
speed of 10 feet per minute (3.05 m/min).  
Fix the film at 65 to 70°F (18 to 21°C) in KODAK  
PROFESSIONAL Fixer, KODAK Rapid Fixer, or  
KODAFIX Solution for 2 to 4 minutes. Move the sheets to  
the fixer one at a time. Continue the agitation.

Wash the film in running water at 65 to 70°F (18 to 21°C)  
for 5 to 15 minutes. To save time and conserve water, you can  
use KODAK Hypo Clearing Agent. First rinse the film in  
running water for 15 seconds. Transfer the stack of film to  
the hypo clearing agent solution and agitate for 112 minutes.  
Then wash the film for 5 minutes in running water, providing  
at least one change of water during this time. Treat the film  
with KODAK PHOTO-FLO Solution and hang it up to dry;  
do not squeegee.

To produce a contrast index of about 1.4, start with a machine  
speed of 8 feet per minute (2.4 m/min). Washing at this speed will  
not provide archival quality, but it should be adequate for many  
scientific recording applications.  
*Sensitivity = reciprocal of exposure (erg/cm2 ) required  
F002_0194AC  
to produce specified density  
* Use a lower dryer temperature (95 to 110°F or 35 to 44°C) with 2415  
Film if spots form due to rapid drying. Lower temperatures may also be  
adequate if you are drying only roll film.

PRINTING  
The 0.1 neutral density built into the ESTAR-AH Base is  
one-half to one-third that found in conventional 35 mm  
picture-taking films. Correctly exposed and processed  
pictorial negatives may appear to be “thinner” than normal.  
It is important to take this into account when you judge the  
printability of negatives.

The micro-fine grain of Technical Pan Film makes  
possible printing at higher magnifications than are usually  
acceptable with conventional picture-taking films.  
Enlargements made at magnifications greater than 25X with  
highly specular (point-source) enlargers may show a random  
distribution of poorly defined white specks in otherwise  
dense areas. The specks are caused by tiny matte particles  
coated on the back surface of the film. You can mask the  
specks, with little loss in the overall sharpness of the image,  
by using an enlarger with a diffuse or semi-diffuse light  
source.
