TRAIL - Long Exposure Camera

Your phone's camera takes one frame. TRAIL keeps them all.

Point at moving light and hold. Headlights stretch into ribbons, a waterfall softens into silk, a torch waved in the air draws a glowing line — and you watch it build on screen while it happens. No processing screen, no waiting.

NEW IN 1.2
• Long exposure from any video: pick a clip from your phone and watch it build
• Self-timer (2, 5 or 10 s), so tapping the screen doesn't shake the shot
• Duration presets that stop by themselves, or Bulb until you tap again
• Pause and resume an exposure
• Steady indicator, grid and level
• Volume buttons and Bluetooth selfie remotes work as the shutter
• Change brightness and look after the shot
• Saves straight to your gallery (TRAIL album); shots taken sideways save upright
• Now in 11 languages

FIVE WAYS TO HOLD TIME
• Light Trails: headlights, city traffic, anything bright that moves
• Comet: trails that fade behind the light instead of staying forever
• Silk: waterfalls, waves and clouds smoothed into one flow
• Light Painting: draw in the air with a torch; only bright light is kept
• Motion Art: soft ghosting for people and crowds in motion

BUILT FOR LONG EXPOSURES
• The exposure builds live on screen, frame by frame
• Frames are stacked in high precision, so long exposures don't band or posterise
• Automatic compensation when the camera's own exposure drifts mid-shot
• Tail length and trail thickness controls
• 8 colour looks
• Save the build-up itself as a video
• Frame in 3:4, 9:16 or 1:1

A FEW HONEST NOTES
Long exposure is a real photographic technique, and it behaves like one:
• It wants moving light. TRAIL stacks what moves; it does not brighten a dark scene the way a night mode does.
• It wants darkness around the light. Pointing at a brightly lit room will wash out. That is the technique, not a fault.
• It wants a steady phone. Rest it on a wall, a railing or a bag, or use a tripod; the timer keeps your tap out of the shot.
• It wants a few seconds. A car crossing the frame takes time.

Get those right and the results are the kind of photograph people stop scrolling for.
