Calibrate camera EV exposure stops, compress blown-out highlights, and recover dark shadows.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Select any underexposed or overexposed photo.
Adjust exposure stops, highlight recovery, and shadow lift sliders.
Download the corrected image in original quality.
EV (Exposure Value) represents photographic stops. +1 EV doubles the light captured by the camera sensor, while -1 EV halves it.
Yes, the shadow lift algorithm expands shadow tone gradients without washing out black levels.
