Production-Ready Calculators You Can Trust
Every calculator on this site is built from the formulas and industry standards that working cinematographers, camera assistants, and producers rely on daily. Depth of field uses the same circle of confusion math found in professional lens charts. Exposure calculations follow the ISO, aperture, and shutter speed relationships defined by camera manufacturers. Storage estimators use real codec data rates published by ARRI, RED, Blackmagic, and Sony.
These are not toy apps. They are practical tools designed to give you answers you can take straight to set. All calculations run in your browser. Nothing is uploaded, stored, or tracked. Your production data stays on your device.

Film school students use the glossary to prepare for classes and exams. Working professionals use it to quickly confirm the precise meaning of a technical term. Aspiring filmmakers use it to build vocabulary before stepping on set for the first time. It is a reference designed to grow with you throughout your career.
