For a lot of us, landscape photography is one of our favourite past-times. Being out with nature doing the hobby you love, really is something we enjoy.
It can get a little frustrating if we're not producing the standard of shots that we would like to however.
Luckily, there's a quick and easy “rule” (or as we like to call them, “guidelines”) that can save your daytime landscapes (or any other daytime shot for that matter), at least in terms of exposure and light.
It's called the f/16 Rule and is sometimes known as the Sunny 16 Rule (or even the Sunny f/16 Rule) and is useful for those who like a guide to landscape photography settings at this time of day.
What is the Sunny 16 Rule?
The basic rule is to shoot at an aperture of f/16 with a shutter speed of 1/125 when shooting at ISO 100.
Or f/16 with a shutter speed of 1 / ISO setting (or as close as your camera settings will allow)
It's basically a way of ensuring a reasonable shot under sunny conditions without recourse to a light meter.
Let's Look at Some Examples of the Sunny 16 Rule
These examples worth with film or digital.
For example, let's say you were shooting on 400 ISO film.
The formula would be f/16 and 1/400 speed.
With ISO 800, it would be f/16 and 1/800 speed.
