DEPTH OF FIELD

1. depth of focus

1.1. in focus

1.1.1. lights rays from point converge on camera sensors point

1.2. out of focus

1.2.1. lights rays hit sensors at different locations

1.3. depends on how far away light rays are

2. calculating depth of field

2.1. based on type of camera

2.1.1. (sensor or film size)

2.2. viewing distance

2.2.1. print size combination

3. circle of confusion

3.1. smaller than resolution of screen

3.1.1. Dependencies

3.1.2. Milestones

3.2. can determine depth of field

3.2.1. occurs when center of confusion is bigger than the camera's pixels

4. focal length

4.1. longer focal lenth

4.1.1. shallower depth of field

4.1.1.1. enlarges background rather than foreground
