sunny 16 rule

For daylight photography, there is a similar rule called the Sunny 16 rule.

Many photographers simply use the f/16-based Sunny 16 rule, unmodified, for lunar photographs.

Apart from the obvious advantage of independence from a light meter, the Sunny 16 rule can also aid in achieving correct exposure of difficult subjects.

In photography, the Sunny 16 rule (also known as the Sunny f/16 rule) is a method of estimating correct daylight exposures without a light meter.

Ultimate Exposure Computer Fred Parker's guide to using the Sunny 16 Rule and an EV scale to calculate exposure by hand.

An example of the use of the law of reciprocity is the Sunny 16 rule which gives a rough estimate for the settings needed to estimate the proper exposure in daylight.

The albedo of the moon's surface material is lower (darker) than that of the earth's surface, and the Looney 11 rule increases exposure by one stop versus the Sunny 16 rule.

An elaborated form of the Sunny 16 rule is to set shutter speed nearest to the reciprocal of the ISO film speed / setting and f-number according to this table:
