Start with the filter pack printed on the film carton. Then add any necessary filters listed in the table under “Filter Recommendations.” Note: Very short exposure times may not be repeatable. Consult the timer manufacturer for exposure limitations. If your exposure is too short for your timer, add neutral density filtration. Caution Consult the manufacturer of pulsed-xenon lamps for ventilation recommendations and information on ultraviolet radiation. 2 KODAK PROFESSIONAL EKTACHROME Duplicating Film EDUPE • E-2529 35 mm Cameras Filter Recommendations You can make duplicate slides with a single-lens reflex When using tungsten illumination, start with the basic filter camera and a suitable slide-duplicating attachment. pack printed on the film box.
