Depth of Field Calculator

What is Depth of Field?

Depth of field is how much of a photo appears sharp and in focus. Sometimes you'll want everything sharp (like in landscape photography), and sometimes you'll want a blurry background to make your subject pop (like in portrait photography).

What This Tool Does

This calculator helps you figure out what will be in focus before you take the shot. Just enter your camera settings, and it will show you:

• How close and how far your sharp zone extends
• The "sweet spot" distance to focus at for maximum sharpness
• A visual guide showing which parts of your scene will be sharp or blurry

How to Use It

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

The tool instantly shows your results and a visual representation of what will be sharp in your photo.

When Is This Useful?

• Portraits: See how blurry your background will be at f/1.8 vs f/2.8
• Landscapes: Find the perfect focus distance to keep everything from foreground rocks to distant mountains sharp
• Group photos: Make sure everyone in the group will be in focus
• Planning shots: Know your settings before you're in the field

No complex photography knowledge needed - just experiment with the sliders and see how changing your camera settings affects your photos!
