Film photographers might be familiar with a handy rule from the days without automation or exposure meters: the “sunny 16” rule. It gives a rough suggestion for exposure, f/16 at the reciprocal of the film speed, which with 100-ISO film would be 1/100th of a second.

I like the idea of “sunny sixteen” much better than the notion of “sweet sixteen” to describe our sixteenth wedding anniversary, as it seems much less of a cliché, and more positive. Sunny.

Abby and I were married on October 12, 2004 at Arches National Park. It was only one day, a beautiful, sunny one, that marked the start of this wonderful marriage.
