Depth of Field Calculator

What is Depth of Field?

Well, it's a phrase. A phrase used to help quantify an aspect of a picture. In photography, depth of field refers to how much of the background will be sharp and in focus. To change the depth of field you adjust your camera lens's aperture, denoted by an italic f and also referred to as an f-stop. As a photographer, they'll be times when you want everything in the frame to be in focus. They'll also be times when you want everything to be blurred.

What This Tool Does

I made this calculator as an experiment. To try and create something that visualizes and displays what depth of field is without a camera. The area your sharp zone extends, if you will. For fun I also added a sweet spot, hyperfocal distance, measurement to visualize where to focus the camera for maximum sharpness across the entire frame given the chosen aperture.

How to Use It

1. Enter your lens's focal length - e.g. 50mm, 85mm, 300mm
2. Choose your aperture (f-stop) - smaller numbers like f/1.8 create more blur, larger numbers like f/8 keep more things in focus
3. Set how far away you're focusing - your subject distance
4. Pick your camera type - from the dropdown

No complex photography knowledge needed! I've included the good, pure numericals as well.
Have a good one!

Forgot to mention, the visualizer breaks when you get to infinity.
