About this app

Off Speed Exposure Comparison | Multi-Camera Exposure Comparison | Optical Density to ND Factor Converter

MatchStop: Exposure Comparison is a comparison tool built for camera professionals working across multiple cameras on set. Quickly compare exposure values between two or three cameras, calculate slow motion exposure adjustments, and convert ND filter values — all in one app.

Important

MatchStop: Exposure Comparison is a comparison tool only. It is not intended for setting proper camera exposure. Always use a dedicated light meter or your camera's built-in metering tools to determine correct exposure for your shot. MatchStop is designed to help you understand the relationship between camera settings, not replace professional metering equipment.

Who It's For

Cinematographers, camera operators, DITs, ACs, and anyone working with multiple cameras who needs fast, reliable exposure comparison on set.
