Fieldframe is a free toolkit for people who make pictures, from wedding and landscape photographers to indie filmmakers and students. It covers the planning questions that come before every shoot: when the light is best, where the sun will be, how much will be sharp, how wide the lens sees, and what you need to shoot.
Paid apps charge for this math. We think it should be free, fast and well explained. Every tool runs in your browser, and your inputs and shot lists are saved only on your own device.
What's here

How we keep the numbers right
Every tool on Fieldframe shows the formula it uses, and each guide explains where the numbers come from. We test each calculator against worked examples from the sources we cite before it goes live, and recheck it when those sources change. Each page shows the date it was last reviewed.
If you spot a result that looks wrong, please tell us. Corrections are the most useful message we get, and we fix confirmed errors quickly.
Why it's free
Fieldframe is paid for by advertising. We don't sell accounts, subscriptions or "pro" upgrades. Every feature is free and works without signing up. Ads are kept away from the tool's buttons and inputs so you don't click one by accident.
