That Ole Sunny 16 Rule


That ole Sunny 16 Rule.


The Winter Solstice is less than a week away, and the last full moon has come and is going away. I have always been fascinated with photographing the moon, much more so since digital photography has made it somewhat easier to do or at least see your results sooner. I have talked about the proper exposure for photographing a full moon, but I still will have some folks email me with exposure questions. I will mention the formula again for those that are interested. Back in the day when calculating exposure was tougher than with these fancy computerized camera (said in my whiny old voice), there was a thing we used called the “Sunny 16” rule. It simply states that “On a clear non-polluted day, when photographing a front lit object, larger than 10 inches by 15 inches, your exposure will be 1/ISO at f16.” Now with a little bit of haze, like we have here in the southeast, you open up a top. Any reciprocal value there of will work as well. So, a full moon is larger than 10×15, front lit, therefore the Sunny 16 rule works. No metering required. I opened up one stop for the haze in the sky. There you go.
