Speed Booster for EKTACHROME Films

There will undoubtedly be times when you'll want to use a very high-speed 35 mm color-slide film. This may occur when you're shooting by existing light, when you want to use a fast shutter speed combined with a small lens opening, or when you need a small lens opening to get good depth of field under dim lighting conditions. For best quality, use the normal speed rating of the film. However, if your shooting situation requires a higher film speed, you can double the rating of most EKTACHROME Films and ask the photofinisher to use push-processing.

Push processing is required for EKTACHROME P1600 Professional Film which is optimized for an effective speed of EI 1600 using a 2-Stop Push. A film speed of EI 3200 is possible with push processing available from some professional labs.

Mark an exposed magazine of EKTACHROME P1600 Professional Film in the appropriate place for the EI used P1 (Push 1) for EI 800, P2 (Push 2) for EI 1600, or P3 (Push 3) for EI 3200.
