2. An Optimized Diffusion Depth Of Field Solver (DDOF) 28th February 2011 2 AMD�s Favorite Effects

Depth of Field shallow:

Depth of Field shallow: A large aperture leads to less focal depth. Wide: If the aperture is small the focal depth will be much wider resulting in an all around clear picture. Shutter Speed Slow When the shutter is open longer, the image if moving will look blurred. Fast!

Depth of Field

Depth of Field. Module 5. A perture is the camera part that controls the amount of light that enters the camera. Aperture is measured in f/stops. The size of the aperture will primarily affect how much of the scene is in focus, the depth of field. .

DEPTH OF FIELD

DEPTH OF FIELD. DEPTH OF FIELD. DEPTH OF FIELD is the distance between the nearest and farthest objects in a scene that appears in sharp focus. The area in which objects located various distances from the camera are in focus. DEPTH OF FIELD. deep depth of field= everything is in focus.

Depth of Field

Depth of Field. Conversely, for a given film position, there is a range of distance at which all objects have acceptable images on the film . This distance is called the depth of field . Within the depth of field, all objects are reasonably clear on the film.
