What is Depth of Field?

Depth of field (DoF) refers to the range of distance in an image that appears sharp. A shallow depth of field means only a small part is in focus; a deep depth of field means most of the scene is sharp.

Depth of field is a powerful creative tool in portrait, product, landscape, and fashion photography.

Why Depth of Field Matters

• Controls focus: Directs viewer attention.
• Creates storytelling: Background blur isolates subjects.
• Improves clarity: Deep DoF ensures everything is sharp.

Three Factors That Affect Depth of Field

• Aperture: Wide = shallow, narrow = deep.
• Distance: Closer subject = shallower DoF.
• Lens focal length: Longer lenses create shallower DoF.

Common Depth of Field Uses

• Shallow DoF: Portraits, products, cinematic shots.
• Deep DoF: Real estate, landscapes, group photos.

Depth of Field Best Practices

• Use wide apertures for isolating subjects.
• Use narrow apertures for everything-sharp images.
• Position subjects carefully based on story and focus.
