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 1 3-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  
13-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,
