Lento: Long Exposure Camera

Lento stacks camera frames in real-time to create long exposures on iPhone. Silky waterfalls, streaking car lights, empty landmarks - no ND filter, no tripod, no guesswork.

SMOOTH

Blur water and clouds into silk. Point at a waterfall, tap the shutter, and watch it smooth out frame by frame.

LIGHT TRAIL

Capture every streak of light. Car headlights, neon signs, star trails - the brightest pixel wins.

GHOST REMOVE

Tourists keep walking through your shot? Lento removes them. The static scene stays, moving objects vanish.

MANUAL CONTROLS

ISO, focus, exposure duration, self-timer. Live readouts update as you shoot. Built for photographers who want precision, not presets.

PRO EXPORT

RAW DNG (16-bit), HEIF, or JPEG. 8 megapixels with EXIF metadata - ISO, aperture, focal length, GPS coordinates.

REAL-TIME PREVIEW

Watch the exposure build live. What you see on screen is what you get in the file.
