Shutter Speed Calculator
This calculator helps determine the appropriate shutter speeds for capturing motion or calculating long exposures based on focal length, subject speed, and desired motion blur.
Shutter Speed Calculator gives you a faster way to work through practical calculation scenarios without rebuilding the same calculation from scratch every time. Start with Focal Length (mm), Subject Distance (meters), Subject Speed (km/h), and Desired Motion Blur and use the live outputs to estimate Minimum Shutter Speed for Sharpness (seconds) and Shutter Speed for Motion (seconds) in one pass. This page is built to help you compare scenarios quickly, validate rough assumptions, and move into a related calculator when you need a second angle on the same problem.
Use The Calculator In A Few Steps
Work through the inputs deliberately, then compare outputs instead of relying on a single scenario.
Scenario Checks
Use these examples to verify the behavior of the calculator before you run your own values.
