Phase One Long Exposures

As with any camera system, the longest exposure a Phase One back can produce before prohibitive noise is produced depends on the ambient temperature of the air. Unlike other camera systems Phase One back’s longest practical exposures are measure in minutes and hours rather than seconds.

Note 1: The following table does not apply to the P65+ which uses a sensor which favors dynamic range over maximum exposure time.

Note 2: Our testing has shown the P45+ to produce the best long exposures.

C F Max Clean Exposure
41 105 8 minutes
35 95 13 minutes
29 84 20 minutes
