SUNNY 16 RULE

When caught without a meter* one can use the "Sunny 16 Rule" as a guide for exposure. There are two steps to the rule* as outlined below:​







STEP 1:Set your shutter speed equal to your film speed. (i.e.* Shutter = Film Speed) Examples: 1/60 for Velvia rated at ISO 50; 1/125 for TMax rated at ISO 100. Note that in most cases* the shutter speed will NOT EXACTLY EQUAL film speed* but will be set as close as possible to the film speed. It's simply easier to remember the rule as "Shutter = Film Speed." STEP 2:Set your aperture equal to f/16 for sunny sky. What if it's not sunny?

If slightly overcast* open one stop to f/11. If overcast* open two stops to f/8. If deeply overcast* open three stops to f/5.6.

How do I distinguish between slightly overcast* overcast and heavy overcast? Examine the shadow detail. If shadows are distinct but soft around the edges* then it's slightly overcast. If shadows are not distinct* but still visible - very soft - then it's overcast. If there are no shadows at all* then it's heavy overcast. The chart below provides a useful summary:

SUNNY 16 CHART
Aperture* Lighting Conditions* Shadow Detail
f/16 * Sunny * Distinct
f/11 * Slight Overcast * Soft around edges
f/8 * Overcast * Barely visible
f/5.6 * Heavy Overcast * No shadows
