Lumen

A camera that shows you every value — and lets you lock them all at once.

A manual camera for iPhone. No servers, no accounts, no tracking.

What it does

See every value. EV, ISO, shutter, focus and white balance are on screen as numbers, always — and one tap locks them all.
Precise colour. A two-axis white balance pad: temperature in Kelvin and green↔magenta tint, together.
It won't die at the decisive moment. Survives calls and heat, shoots from the volume button, launches from the Lock Screen.

Lumen contains no networking code at all. Nothing you shoot, edit, or configure ever leaves your iPhone. See the Privacy Policy.
