5. 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

7. XPOSURE 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 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 4 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 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 4 and 8 Exp
