natural light occurs in three times, two times, daylight and night, are stable times, not static but limited in amount of change once they’ve taken hold of the day. exposures can be tested, and settled upon in either daylight or nighttime, it is during the third phase of the day, that of dusk and dawn, these are the times of great change. your meter will fail you, even as the light will.

reciprocity won’t save you now!
