| + | ====== Sunny 16 Rule ====== | ||
| + | Sunny 16 rule says that in a sunny day, shooting shall set the shutter to the same ISO as the film and the aperture to f/16 to maintain the correct amount of light to come through. Setting shutter at the double of speed of ISO shall open the aperture to double in size as well, i.e. f/8. | ||
| + | |||
| + | In case the lighting condition is different, the f-stops shall be changed: | ||
| + | * Beach or snow: minus one stop (f/22) | ||
| + | * Bright daylight: f/16 | ||
| + | * Weak light, sun low in the sky: plus one stop (f/11) | ||
| + | * Cloudy: plus two stop (f/8) | ||
| + | * Dark clouds or in shadow: plus three stop (f/5.6) | ||
| + | * Sunset: plus four stop (f/4) | ||
| + | The above assumes you are shooting the ground, not the sky. | ||
| + | |||
| + | Beach or snow condition means lights reflecting around, hence the lights is effectively stronger. The sunny 16 rule applies when the shadow has a sharp and hard edge. | ||
| + | |||
| + | Cloudy means there is no shadow formed. In case of an shaded environment, that is "dark clouds". | ||
