Aperture Settings

Thin depth of field

Medium depth of field

 Aperture settings determines the depth of field on a shot. The size of the hole on the lens that lets in the light reacts with cells at the back of the camera to form a visual image.
The size of the aperture can be adjusted to let more or less light in. The size is determined with the F-stop setting. On most SLR cameras, the smallest F-stop setting is F22, and the largest is F3.5.
F3.5 will give a thin depth of field, F9 will give a medium depth of field, and F22 will give a thick depth of field.
One particular problem with seeking a thick depth of field would be camera shake. Camera shake is possible because with a higher F-stop setting, the shutter speed decreases and this means that the camera has to be held in an exact position for a longer period of time. This can be especially frustrating when the camera is either held in hand, or in a precarious position. In order to tackle this problem, a tripod can be used which ensures camera stability.
