Depth of Field is broken up into three layers (or region); Near, Far, and the Focal Region. Each of these is processed separately and then later composited together to achieve the final image effect. Objects in the Near and Far layers are always fully blurred. They are blended with the non-blurred scene to achieve the final result. 1. To get deeper DoF at the same focal length and focus distance, you need to narrow the aperture. Another option to get something too close in the foreground into the DoF is to move your shooting position back until the desired element in the scene is within the DoF for your selected aperture. First, you must realize that depth of field (DoF Hyperfocal Focusing. Hyperfocal focusing is based on the fact that depth of field typically extends 2/3 behind the point focused on and 1/3 in front, but if you focus on infinity, the depth of field behind is completely wasted. You can make use of it if you refocus, putting the infinity mark (an “8” on its side) on the focusing ring against Preference mostly IMO. Turning it off would increase performance a bit in exchange for less scenic views. 2. Gawd_Awful. • 3 mo. ago. Preference.
