The first step in complete control of the camera - the aperture control

What is Aperture?
Simply - Aperture is "shooting the size of the lens opening."
When you press the shutter on the camera, there will be a hole is opened to allow the sensor to capture light enters the camera jvc bn-v11u battery(Translator's Note: the actual aperture is always open, when you press the shutter to set the value of the contraction.) You set the aperture value to influence the size of the hole to open. The larger the hole open, there will be more light in, the smaller the hole open, the less light to enter.
Aperture is the "f /" marked. You will often see in the photo tutorial f / value, such as f/2.8, f / 4, f/5.6, f/22 and so on. Change the time f / value, the size of the lens in the hole becomes double or half the current size, the amount of light also will be doubled or reduced by half.
Photography JVC BN-V514U Charger for beginners will often confuse one reason the aperture, f / number of smaller, then the greater the aperture (the more the amount of light), whereas f / number is larger, the smaller the aperture. So f/2.8 aperture is larger than the f/22 aperture. Must not be confused.
Depth of field and aperture
Change the aperture will cause many of filming, one of the most notable is the depth of field problems.
Depth JVC Batteryof field (DOF) refers to the focal plane before and after photos in a clear picture of the part. Great photos both near and far depth of field means that most of them are clearly still life (such as photos taken with the f/22 aperture in the foreground and background are very clear.)
Small (or shallow) depth of field means that only part of the picture screen is clear of other virtual images are lost.
Aperture plays an important role on the depth of field. Large aperture (small f / value) will reduce the depth of field, small aperture (large f / value) to increase depth of field.
For the first time you see these may cause some confusion, but I remember this way: a small f / value is equal to the small depth of field, large f / value is equal to the depth of field.
The following picture illustrates the shallow depth of field:
The figure is taken with the f/1.8 aperture, in addition to the top of the two flowers, the flowers are all behind the blur, the flowers and leaves come out from the background (Translator's Note: Original link failure, this Photos taken by the translator, and is explaining.)
The best way to understand Aperture is to go out with your camera to do some exercises. Find a scene out, there is also an object close to your distant objects, taken with different aperture a group photo. You will soon see the impact and role of the aperture.
Different subjects require different depth of field photography
For example, in most of the landscape photography, you will see many photographers choose a small aperture. This ensures that the distance from the foreground to the horizon are clear all the still life.
On the other hand, in portrait photography, the aperture can be easily used to make models of clear and the background is empty, so you can highlight the model, so that other things will not divert the audience's attention. At this point you have to choose a large aperture to ensure a small depth of field.
Dumping macro photographers tend to use large aperture, to ensure that the subject can grasp the audience's full attention, while ignoring all the other content.jvc bn-v20u battery
