Sunny 16 - A simple rule of photographic

Regola del f/16

Sunny or Sunny f/16 Rule 16 is a mnemonic used by photographers to remember a particular setting for correct exposure to sunlight. Initially developed for film photography (which is obvious, since many of the "ground rules" that circulate in this environment, as the above, born for film photography) to help determine the exposure without the use of light meters, Sunny 16 can also be applied to digital photography.

The basic rule states that, in a sunny day, the photographer must set the aperture to f/16 and duration of roughly the same value in hundredths of a second, in relation to ' ISO View definition in a new window in use.


For example, if the photographer is clicking to ISO 100, the duration of exposure should be about 1/100, maximum 1/150. With ISO 200, opening speed equal to 1/200, maximum 1/250 and so on.

The identities of f-stop, ISO and exposure time can be appicati any lighting condition, with minor variations:

  • f/16 - sun, distinct shadows
  • f/11 - slightly overcast, shadows have soft edges
  • f / 8 - overcast, shadows are seen just
  • f/5.6 - overcast, no shadows visible

With the option to auto exposure cameras present on today is easier than most of the work the machine do it automatically. However, when shooting is always good to keep in mind the basic rules of photography.

    S16 THE RULE, NOT MUCH OF AGREEMENT. THE CHANGES: Aperture F /, INVOLVES THE RISK / MAKE A PICTURE OF HONOR IN MANY WAYS.

    IF YOU HAVE A F / 5.6 BACKGROUND WILL 'out of focus. IF IN A LANDSCAPE WITH A Fence, THE FUND MAY 'IS NOT A GIVEN THAT GREAT.
    EVEN IF YOU CAN 'BE VERY SUGGESTIVE. MAYBE IT WAS A BETTER F/22

    ON THE CONTRARY, AND MAYBE USE A F/22 MY CHILD WITH A BACKGROUND OF THE CAR, YOU WILL BE ALL INCLUSIVE 'NOT A FIRE AND RISULTARA' VERY BEAUTIFUL. MAYBE IT WAS A BETTER F / 5.6

    WHAT I WANT TO SAY 'THAT THE RULE AND S16' LIMITED TOO. FIRST OF ALL I NEED TO KNOW WHAT I WANT FROM PHOTOS. A PORTRAIT (blurred background) OR AN OVERVIEW (ALL IN FIRE). HERE IS A THINKING F / TOO HIGH OR LOW STATIC OR THAT INVOLVES AN IMAGE LIKE THE MOVEMENT.

    THE SUM OF TWO RULES MI DOOR TO CHOOSE AN F / + 1 / TIME 'S CORRECT.

    BUT TODAY THE DIGITAL COMPACT THAN EVEN HAVE THE GREAT SPEED 'TO HAVE THE "SCENE". HERE I HAVE TO DO OR WANT TO KNOW WHAT I AM TAKING PICTURES AND THE MACHINE IS ALONE.
    SCENE "PANORAMA" = AND ALL THINGS WILL BE A FIRE.
    SCENE "MOVEMENT" THE SPEED = 'aperture (1 /) BE' FASTEST IN A WAY THAT WILL NOT 'MOVE.

    And so on.

    Thanks for the advice. If you want one from me when comments, do not hold your caps lock down

    Hello Max
    I think you do not fully understand the rule of 16.
    The rule consists in finding a pair of "standard" time / aperture to f16 considering the fact that, in a sunny day, you can use a time approximately equal to 1/125 (with ISO 100). Defined this parameter can vary both the time that the diaphragm considering the maintenance of their relationship.
    eg. when you have placed the couple, f16-1/125 suppose, if you want to increase the aperture you can get varying times and would result in our example f5.6-1/1000.

    soon
