Kodak Vision3 camera film normally is developed for 3 minutes at 41 C (106 F). If the film has been underexposed it needs to be overdeveloped by increasing the development time (pushing the film). If the film has been overexposed it needs to be underdeveloped by reducing the development time (pulling the film). Kodak recommends the following developing times for all Vision3 films:
Push +2 stops: 4 minutes 40 seconds (56% increase)
Push +1 stop: 3 minutes 40 seconds (22% increase)
Normal: 3 minutes
Pull -1 stop: 2 minutes 30 seconds (17% decrease)
Rapid development times are needed for motion picture film because such large volumes are involved. A 35 mm print for a feature film will have a mile or more of footage, and the production company may expose more camera film than will go into the final print by a factor of 4 or more.
Commercial labs use automated machines to eliminate the human factor. For developing by hand in a small tank at home it is recommended to have developing times at least 5 minutes long to get consistent results. Reducing the developer temperature will increase the time needed to process the film, but may result in a color shift. Some experimentation will be needed.
