Selective Focus/Blur

The targeted use of the depth of field by adjusting the aperture, the distance and focal length allow the viewer's gaze to focus on the main subject. The photographer limits the depth of field as narrow as possible around the level at which the main motif is located. The foreground and background become blurred displayed. This selective blurring distracts less from the main subject, which is accentuated by the selective sharpness.

Practical Tip

With almost every digital camera, there is a setting in which you can only determine the aperture and the camera automatically sets the exposure time. This is called automatic timing or aperture preselection and is marked as "Av " on Canon cameras. This offers you the freedom to concentrate fully on the composition and depth of field. Next time, take a picture of your object in a wide variety of aperture settings and then compare the depth of field. But be careful, with Av , you always have to keep an eye on the exposure time selected by the camera!
