About
Lumen is an on-device AI camera for still photos. It reads the scene live — faces, light, motion, landscapes — and continuously tunes focus, exposure and tone for you. Then it finishes each photo with a hand-crafted analog film-style color rendering (still photography only — Lumen does not record video).
MACRO MODE, BUILT IN
Lumen brings a tool usually reserved for professional manual-focus cameras into a simple point-and-shoot: real-time focus peaking colors the sharpest edges red as you shoot, so you always know exactly what's in focus — essential once depth of field gets razor-thin up close.
Turn on Focus Stacking and Lumen captures a quick burst at different focus points and merges them into one photo, sharp from front to back — entirely on your iPhone, no desktop software required. Works best with a steady hand or a small tripod.
TWO MODES
• AI · 12MP — full scene-aware processing plus your chosen film-style color look.
• Max Quality · 24MP — Apple's full-resolution photo pipeline, no filters, for maximum detail.
COLOR LOOKS
Eight color renderings inspired by classic analog film stocks: Standard, Classic, Eternal, Brass, Contemporary, B&W HC, Selenium and Sepia. Swipe to compare; the active look glows.
PORTRAIT MODE (Pro, LiDAR devices)
Real background blur built on your iPhone's LiDAR depth data, not a software guess. Choose an f-stop from f/1.4 to f/8 and Lumen scales both the blur strength and the depth-of-field zone the way a real lens aperture would — a lower f-number gives a shallower, more dramatic zone of sharpness, a higher one keeps more of the scene readable. Requires iPhone 12 Pro or later Pro models.
