What’s the
Sunny 16 Rule?
What’s Sunny 16 Rule? The Sunny 16 Rule states that when you’re utilizing an aperture (or f-stop) of f/16 on a transparent sunny day, you’re inspired to make use of a shutter velocity that’s the similar as your ISO worth. For instance, in case your ISO is ready to 100, you utilize a shutter velocity of 1/100. In case your ISO is 400, you utilize a shutter velocity of 1/400, and so forth.
That being mentioned, remember the fact that not all worthwhile, resembling an ISO of 3200 shot with a shutter velocity of 1/3200 (you’d by no means want such a excessive ISO on a vibrant sunny day).
The Sunny 16 Rule is meant to be a fast photographer’s information to some easy settings for a superb publicity.

Increasing on
the Sunny 16 Rule
The Sunny 16 Rule will not be an end-all-be-all. There are methods to increase upon this rule. You need to use Sunny 16 to calculate the connection between different aperture values and the shutter velocity and ISO values.
Bear in mind concerning the relationship between aperture, shutter velocity, and ISO, also called Publicity Triangle.
In the event you improve or lower any considered one of these variables, the others should improve or lower with the intention to preserve the publicity the identical. A fast information to recollect how these variables have an effect on publicity is as observe:
- Extensive aperture (smaller quantity) = Lighter picture.
- Slim aperture (bigger quantity) = Darker picture.
- Quick shutter velocity (bigger quantity) = Darker picture.
- Sluggish shutter velocity (smaller quantity) = Lighter picture.
- Excessive ISO (bigger quantity) = Lighter picture.
- Low ISO (smaller quantity) = Darker picture.
If one issue goes up by one cease, one other issue ought to go down by one cease. The commonest examples are as such:
- f/16 – 1/100s – ISO100 – Primary Sunny 16 Rule
- f/11 – 1/200s – ISO100 – Modified Sunny 16 Rule (aperture +1 cease, shutter velocity -1 cease)
On Fujifilm cameras, the essential ISO is 200 and I want to regulate my Sunny 16 Rule to replicate it.
- f/8 – 1/800s – ISO200 – (aperture +2 stops, shutter velocity -3 cease, ISO +1 cease)
Variations of
the Sunny 16 Rule
There are variations to
the Sunny 16 Rule that may be utilized to totally different climate circumstances. As you
can think about, you received’t at all times have a wonderfully clear sunny day (even in
Southern California!). These variations come within the type of totally different
apertures:
- Snowy or sandy circumstances: f/22
- Clear and sunny circumstances: f/16
- Barely overcast: f/11
- Overcast: f/8
- Heavy overcast: f/5.6
- Open shade or sundown: f/4
It doesn’t imply that I’ve to make use of f/22 when photographing snowy scenes. I extra prone to regulate the Sunny 16 Rule to the next numbers: f/11 – 1/800s – ISO200 (aperture +2 stops, shutter velocity – 3 stops, ISO +1 cease, Fujifilm bear in mind?)
As soon as once more, the Sunny 16 Rule is a suggestion solely.
