KODAK EKTAGRAPHIC HC Slide
Film
KODAK EKTAGRAPHIC HC Slide Film is a negative-
working, orthochromatic film that is designed for making
reverse-text black-and-white title slides (e.g., if your
originals have black letters on a white background, they will
reproduce as white letters on a black background). This film,
features extremely high contrast, and wide exposure and
development latitude—you get high contrast with opaque
blacks and clear whites.
SIZES AVAILABLE
STORAGE AND HANDLING
Store unexposed film at 75°F (24°C) or lower in the original
package. Always store film (exposed or unexposed) in a
cool, dry place. For best results, process film as soon as
possible after exposure.
Protect processed film from strong light, and store it in a
cool, dry place. For more information on storing negatives,
see KODAK Publication No. E-30, Storage and Care of
Photographic Materials—Before and After Processing.

EXPOSURE
To find the best exposure for your copying equipment when
first using this film, make a trial exposure series. Adjust the
camera f-stop in
1
⁄
3
-stop increments for a total of 7
exposures (3 above and 3 below your starting point). To
determine the starting-point exposure time and aperture
setting for the series, measure the illumination on the
original material. Take a direct reading with an incident-light
meter, or read a gray card (18% reflectance side) on the
copyboard with a reflected light meter. Set the exposure
meter at Exposure Index (EI) 25 if the film will be developed
in KODAK Developer D-11, or EI 8 if developed in KODAK
PROFESSIONAL KODALITH Super RT Developer (see
“Processing”).
To determine your first set of trial exposures, set the
shutter speed at 1 second and make an exposure at every
f-stop on the lens. Record the f-stop of the best exposure and
note the lens and lighting arrangement; use these data as a
starting point with other originals. After this initial test,
bracket two stops on each side of the best exposure using
1
⁄
3
-stop increments; exposures will vary somewhat with the
width of the lines and the type size of the artwork.
Example: With four 200-watt tungsten lamps, two on each
side of the original, and the shutter speed set at 1 second, the
best exposure should be between f/5.6 and f/11. If you use
two 200-watt lamps, one on each side of the original, the best
exposure should be between f/4 and f/8.
