Sunny 16 Rule

ok.. so i've been searching, reading about the sunny 16 rule. many webs with all the information... ALOT of information... too much!!! just too much to read.. lol.

trying to compile a shorter, 'simplier', (but probably not as much information/details) for the Sunny 16 Rule.

Aperture

An aperture is a hole or an opening through which light is admitted.

Simply, smaller the number, bigger the ‘hole’.

The usual set of numbers used in photography. (in full-stop)
1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, 45, 64, 90, 128, etc.

In photography, the lens aperture is usually specified as an f-number. Eg. F/2.8, f/8 etc.

Shutter Speeds

Shutter speed
is the length of time a shutter is open.

The Standards values (in seconds) :
1/1000 s , 1/500 s , 1/250 s , 1/125 s , 1/60 s , 1/30 s , 1/15 s , 1/8 s , 1/4 s ,1/2 s , 1 s
Values are normally doubled.

Sunny 16 Rule

The sunny 16 rule (or, less often, the "sunny f/16 rule") is a method to estimate correct daylight exposures without using a light meter.

How to use :-

The shutter speed is set to the nearest ISO speed of the film.

Eg. Film ISO 100 = shutter speed 1/125s
Film ISO 200 = shutter speed 1/250s

Aperture used should be as below.

Sunny - f/16
Slight Overcast - f/11
Overcast - f/8
Heavy Overcast - f/5.6


So for example :-
Sunny day, film 400 :-
Should be using ~ aperture f/16 + shutter spd 1/500s.


ps. damnit.. like also alot to read ... /faint
