## What is Lumen?

Lumen is a camera that doesn't hide its values.

EV, ISO, shutter, focus and white balance are on screen as numbers, always —
and one tap locks all of them. Recompose without your exposure drifting.

■ Precise colour — free
Temperature in Kelvin and green↔magenta tint, together, on one two-axis pad.
A precision the competition doesn't offer. In Lumen it's free.

■ It won't die at the decisive moment
Survives incoming calls and thermal throttling.
Shoots from the volume button. Launches straight from the Lock Screen.
All of that is free too.

■ Free, forever
Auto shooting · EV compensation · tap to focus · two-axis white balance ·
lens switching · histogram · grid · level · burst · volume shutter ·
Lock Screen launch · photo library · the basic editor

■ Lumen Pro
· Manual mode — ISO, shutter, focus
· One-tap lock — every value at once
· RAW · DNG · RAW+JPEG
· Video — 4K, interval, time-lapse
· All 22 filters + the full editor (with tone curve)

■ Privacy
Lumen contains no networking code at all.
No servers, no accounts, no analytics, no ads, no tracking.
Nothing you shoot or configure ever leaves your iPhone.
