About Depth of Field Calculator
The Depth of Field (DoF) Calculator is an essential tool for photographers to determine how much of an image will be in sharp focus. Whether you are shooting landscapes (requiring deep focus) or portraits (blurring the background), knowing your parameters is key.
Key Factors
- Focal Length: Longer lenses have narrower depth of field.
- Aperture (f-stop): Lower numbers (f/1.8) blur the background; higher numbers (f/11) keep more in focus.
- Subject Distance: The closer you are to the subject, the thinner the focus plane.
- Sensor Size: Crop factor affects the effective DoF.
How to Use
Select your camera sensor type (Full Frame, APS-C, M4/3), enter the focal length (mm), aperture, and distance to subject. The tool calculates:
- Near Limit: Closest point of acceptable sharpness.
- Far Limit: Furthest point of acceptable sharpness.
- Total Depth: The total zone of focus.
