One of the effects that bring more realism to an image synthesis is obtained by focusing an object or region located at a distance of cámara.Simula the human eye to focus attention on a particular object, finding other objects more or less blurred.
In photography this effect is known to focus / blur and depth of field of the image, being the result of two factors, aperture and shutter speed.
By depth of field traditionally understood in optics, and photography en particular, as the area in which the image captured by the target is sharp (is focused), so that in the photograph which perform, people and objects located within that area will also appear sharp.(W)
Rendering made with “Cycles” Blender allows you to define the field profundid very easily. Will select in the scene the camera and go into the menu for your configuration by clicking its icon.
The following section will access “Deph of field” that is within this menu.
The two main parameters are “Focus” and “Aperture”.
- “Focus” determines the object we want to be focused.
- “Radius” specifies the degree of blurring of the elements that are closer or farther. A null value blurs the image; high values further blurs the selected object environment.
In the following examples show visually the variation produceen a scene to change the parameter “Radius”
