Depth of Field (DOF- Depht of field) photographs term that refers to a sufficiently sharp focus area real focal point at the front and rear. In other words, focusing on a specific point, some areas of this paragraph, the front and rear axle. This area is called the depth of field.
This simple illustration shows that the camera is in focus in the middle of an existing object (3 m). Both the person in front of the object (2 meters), and the person behind the object (4.8 m) are visible enough axis. However, the same person at the front and in the back looks fuzzy. In this case, the depth of field is from 2 m to 4.8 m.
Depth of field is determined decostar by several factors. The first of these is the lens aperture or ƒ / step. Aperture of variable size opening through which light enters the camera. The larger the aperture, the more light enters. The smaller the hole, the less light penetrates. The orifice size determines the amount of depth of field. decostar The larger the aperture, the less depth of field. The smaller the hole, the greater the depth of field. Below are the standard ƒ / steps.
Next, existing images can be seen as the distance from the object (in combination with different apertures) changes the depth of field. Pay attention to how blurry the camera looks the same front and back (photographed by step ƒ / 2) and the axis are shown in the lower photograph (photographed by step to ƒ / 11).

Depth of Field Management SLR (such as the Nikon D5100 or D7000 SLR) is simple. Disposable SLR interchangeable lenses Nikon is usually decostar a wide range of customizable ƒ / step range, so that the photographer has full control. For compact cameras due to their design is usually not so wide aperture choice or the possibility to manually adjust the aperture. They can get some guidance, but they are not simple and not at the same level as the SLR. Some COOLPIX cameras are available in aperture priority mode, the user can use to select the camera aperture used. If COOLPIX camera does not have this option, many cameras have scene modes, decostar which are programmed to a small depth of field (portrait scene mode is isolated object) or the maximum depth of field (landscape scene mode). These scene modes the user can use it to a certain extent, decostar adjust the image depth of field.
