limiting focus definition
Limiting focus is a technique in which photographers and other artists can limit the area of their pictorial compositions that are in focus. It is a method of simplification, helping the viewer to focus on exactly what the artist wishes the viewer to look at in a picture. A typical example is a close-up of a flower with the background behind it being blurry. This technique can be achieved in photography by using a wide aperature when taking a picture to limit the depth of field. Everything that is not the main focus of the shot will be blurry.
