Estimated running time of a D8 spool with 2×7.5m (2×25ft) film at the most typical frame rates:
18 frames per second ≈ 3min 42s (1min 51s / side)
24 frames per second ≈ 2min 46s (1min 23s / side)
(Calculated running times, may vary by camera model)
NOTE: The developed KAHL UT 21 film can be viewed on a projector as the colors of the film are turned from negative to positive in the development process (hence the reversal film) and the film is spliced into two 8mm film strips.
After development the KAHL UT 21 positive can be scanned into a digital format.
