—NOTICE—

EXPOSURE

This film has been discontinued.

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 ¹₃-stop increments for a total of 7

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.

⁄

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.

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.

such as KODAK Opaque Black, CAT 146 4312. Many of the

black pens and pencils sold for marking overhead projector

transparencies also work well in this application.

ARTWORK

Cleanliness and good contrast are important for best results.

Use black ink, black crayon, black transfer letters on a white

background, black letters obtained from a lettering machine,

or type set by a local printer. Try to maintain an even density

of black. Also make sure that the lettering or artwork meets

minimum legibility requirements.

IMAGE-STRUCTURE CHARACTERISTICS

The data in this section is based on development at 68°F

(20°C) in KODAK Developer D-11 for 2 minutes in a small

tank.

COPYING PROCEDURE

Characteristic Curves

When you are making slides of lettering or artwork, a single-

lens-reflex camera offers a decided advantage because you

can compose and focus the image in the camera viewfinder.

You may need a supplementary close-up lens or macro lens,

especially if the artwork contains fine detail.

We recommend that you use a matched pair of 200 W

tungsten lamps or two tungsten-halogen photolamps, in a

fixed position, for illumination on the sides of the copy

stand. Determine the best shutter speed and lens aperture

combination for a given lighting setup and title by a trial

exposure series, using the suggested exposure index (EI) as

a starting point. Use EI 25 when processing in KODAK

Developer D-11 and EI 8 when processing in KODAK

PROFESSIONAL KODALITH Super RT Developer.

One method to determine the initial exposure time and

aperture setting (f/number) for the test series is to measure

the illumination on the original material. Take a direct

reading with an incident-light meter, or read a gray card with

a reflected light meter. You’ll find that the built-in camera

light meters tend to underexpose white copy material

because they average the reflected light from a wide area of

the scene. However, you can use them satisfactorily with a

gray card.

Another method for determining your first set of trial

exposures is to set the shutter speed at 1 second and take a

shot at every f-stop on the lens. Record the f-stop of the best

exposure and note the lens and lighting arrangement so you

can produce good results again in the future.

COLORING THE SLIDES

You can color the dry transparency by using a cotton swab to

apply the dye or by dipping it in water-soluble dyes, such as

KODAK Liquid Retouching Colors, CAT 190 1743, or

ordinary food coloring.

An alternative to using dyes is to mount a colored filter

with the slide. Theatrical gelatin filters are available in sheets

in a variety of colors and shades.

OPAQUEING THE SLIDES

One of the advantages of reverse-text slides made from high-

contrast black-and-white films is the high-density

background, which can conveniently cover up imperfections

in the background of the original artwork. If, however, any

dirt, sketch lines, or other objectionable marks on the art are

reproduced on the processed film, these white marks can be

easily painted out with opaque, a light-blocking compound,
