Aperture Effects
How aperture affects depth of field and light intake
Aperture Reference Guide
- Shallow depth of field
- Excellent for low light
- Isolates subject from background
- Balanced depth of field
- Good sharpness for most lenses
- Versatile for various situations
- Maximum depth of field
- Ideal for landscapes
- Requires more light or slower shutter
- 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.
