Understanding Aperture & Depth of Field

Every time talk about photography and cameras, the words aperture and depth of field will often come out. Well in this article belfot will try to help you understand aperture and depth of field so that clear enough for beginners.

Understanding Aperture

Definition large aperture lens is a measure of how open (aperture) when we take photographs.

When we pressed the shutter button, the hole in front of the camera sensor we will be open, well-aperture setting that determines how big the hole is open. The bigger the hole open, the more light will enter the number read by the sensor.

Aperture or aperture is measured in f-stops. Often we read the term openings / 5.6 aperture, the more formal language of photography can be expressed as f/5.6. As noted above, the main function of the aperture is as controlling how big a hole open in front of the sensor. The smaller the f-stop number means the bigger the hole is open (and the more the volume of the incoming light), and conversely, the larger the number the smaller the f-stop open-pit.


So in reality, f/2.8 aperture setting means that a much larger aperture than f/22 setting example (you'll often find the term fully open when I hear chatter photographer). So the smaller the aperture width means its f-number and narrow aperture means greater numbers of his f.

Understanding Depth of Field

Depth of field - DOF, is a measure of how far the field of focus in the photograph. Depth of Field (DOF) which means most of the width of the object image (of the object closest to the object farthest from the camera) will look sharp and focused. While the narrow DOF (shallow) meaning only part of the object at a certain point are sharp while the rest will blur / out of focus.


  To get a wide DOF use a small aperture setting, let f-22 (the smaller the aperture wider focal length) - see example photo above. While to get the narrow DOF, use the aperture as much as possible, eg f/2.8 - see example photo below.
The concept of depth of field will be more useful, especially in portrait photography and macro photography, but actually all specialties will be needed.
