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 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 and is useful for those who like a guide to landscape photography settings at this time of day.
It's basically a way of ensuring a reasonable shot under sunny conditions without recourse to a light meter.
The basic rule states to shoot at an aperture of f/16 with a shutter speed of 1/125 when shooting on ISO 100 film.
Or f/16 with a shutter speed of 1/ISO setting (or as close as your camera settings will allow)
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.
