Depth of Field

What it is

Depth of field (DoF) refers to the distance between the nearest and farthest objects in a shot that appear acceptably sharp. It’s controlled by the camera’s aperture, focal length, and distance to the subject.

Why it's important

DoF influences how focused or cinematic your footage looks. A shallow depth of field isolates your subject with a soft background (bokeh), while a deep depth of field keeps everything in sharp focus, useful for documentaries or landscapes.

When/how to use

Use shallow depth for interviews, portraits, or emotional focus. Use deep depth for landscapes, wide shots, or scenes where all visual information matters.

Best Practices

Match DOF to mood – Use shallow depth for intimacy/emotion and deep focus for clarity of environment.
Control with aperture – Adjust f-stops, focal length, and distance to subject to manipulate focus range.
Guide viewer attention – Blur distractions and emphasize the subject by selectively narrowing depth of field.
