Aperture Effects

How aperture affects depth of field and light intake

Aperture Reference Guide

Wide Aperture (f/1.4 – f/2.8)
  • Shallow depth of field
  • Excellent for low light
  • Isolates subject from background
Medium Aperture (f/4 – f/8)
  • Balanced depth of field
  • Good sharpness for most lenses
  • Versatile for various situations
Narrow Aperture (f/11 – f/16)
  • Maximum depth of field
  • Ideal for landscapes
  • Requires more light or slower shutter
Very Narrow (f/18 – f/22)
  • Extreme depth of field
  • Possible diffraction softening
  • Use for maximum front-to-back sharpness

Understanding Aperture

What is Aperture?

Aperture refers to the opening in a camera lens through which light passes to enter the camera body. It is expressed as an f-number (f-stop), which is the ratio of the lens’s focal length to the diameter of the entrance pupil.

A lower f-number (e.g., f/1.8) means a larger aperture opening, allowing more light to reach the sensor. A higher f-number (e.g., f/16) means a smaller aperture opening, allowing less light to reach the sensor.

Depth of Field & Hyperfocal Distance

Depth of Field (DoF) is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image.

Hyperfocal Distance is the focus distance that maximizes depth of field, making everything from half that distance to infinity acceptably sharp.
