Depth of field

1. Controlling Depth of Field

1.1. Large aperture and closer distance produce a shallow depth of field

2. Focal Length and Depth of Field

2.1. depth of field affects focal length

2.2. wide angles provide a more fading dof

2.3. longer focal length appear to have a shallower dof because of the enlarged background

3. Calculating Depth of Field

3.1. Appropriate maximum for circle of confusion

3.2. Based on camera and viewing distance/print size

4. Depth of Focus and Aperture Visualization

4.1. distance over light focused on camera

4.2. when objects is in focus light rays originate from point of coverage

5. range of distance that appears sharp, it gradually transitions

6. Circle of Confusion

6.1. how much a point should be blurred in order to be perceived as sharp

6.2. 0.01 in. is a standard depth of field marker

6.3. Can become larger than your digital camera's pixels

6.4. Is impacted by print size and viewing distance
