What is aperture? it is one of the things that can make a photograph dimension. Thanks to the aperture, the pictures miraculously produced.
For simplicity, the aperture is the size of the lens opening when the photo was taken.
Aperture? Yes, the aperture is a hole in the lens. This entry hole where light can be set magnitude. If the hole the greater the incoming light will be increasingly, and vice versa.
Do not be surprised if you see these numbers [highlight color = "yellow"] f/2.8, f / 4, f/5.6, f / 8, f/11, f/16, f/22 [/ highlight] and so on. These are numbers that represent large-small aperture.
The thing to remember is f/2.8, larger than f/16. Moves from f/2.8 to f / 4 will reduce the light one f-stop. The order of the aperture in the highlights above are standard sequence in one f-stop.
That often confusing newbies is the value of a small number like f/2.8 turns out, large aperture (where the light coming more). Remember, f/2.8 is a large aperture and f/22 is a small aperture. It might sound strange, but over time we will get used.
Aperture and Depth of Field.
Aperture determines the dimensions of our photos. More precisely is the setting depth of field or depth of field (DOF). It will impact directly to the DOF.
Large aperture (f/2.8) will make the DOF gets thinner, it is often used for portrait photography. Because it can isolate objects with the background. If you look at portraits with background blurry, then certainly the photographer using a large aperture.
In contrast to landscape photography, photographers need a wide DOF. From the object closest to the camera up to a distance, as much as possible focus. It is time we using a small aperture (f/22). We can also apply the principle of hyperfocal distance.
The most important thing to do is do the experiment yourself. Use aperture creatively, you might want to try photographing landscape with f/1.8? Not a problem!
