Phase One and 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. Also, when taking several exposures back-to-back without any pause the exposure time accumulates towards these limits on longest exposures.

*We’ve found that although all five of these backs do exceptionally high-quality long exposures that the P45+ is the best of the group. It produces the best long exposure of any camera we’ve tested.
