Alpha Auto correction

One click brings the colors back — as a starting point.

DepthLight analyses every photo on its own: how much red the water swallowed, where the water is and what is the subject. It brings the colors back without turning blue water purple or sand orange, and leaves good photos almost untouched. The one click is where you start, every slider stays yours.

Drag the sliders. Every result is DepthLight Auto with default settings — no presets, no masks, no manual adjustments.

Details for pros

Automatic correction

  • Water model Estimates the light path through water (depth + distance to the subject), using the camera’s depth sensor or your dive log when available — or set it by hand.
  • Red rebuild Rebuilds red, orange and yellow from the remaining channels, only where they are actually missing.
  • Knows its limits Measures how much correction a photo needs. Strong casts are fixed fully; already edited or neutral photos are left alone.
  • Special situations Recognizes green or lake water, murky yellow-green water, red-filter shots, night and lamp shots, strobe light cones, the camera’s underwater mode — and photos taken above water.
  • Open water stays blue Water is detected and protected, so it stays deep blue instead of turning grey or purple.
  • Stays automatic while you edit Your sliders are offsets on top of Auto, which keeps measuring the result.
  • RAW done properly For RAW files, white balance is solved in Apple’s RAW engine on the sensor data. Works with the RAW formats macOS supports; tested mostly with OM System / Olympus.

Underwater tools

  • Backscatter removal Removes particles in open water only, with strength and particle size — and a view that shows the detected specks in red.
  • Water & depth presets Red Sea, Caribbean / Maldives, Snorkeling, Diving, Deep, Green water / lake, Strobe / light.
  • LED light preset For photos lit with a video or dive light: LED light lacks deep red, the preset brings red and orange back while the water stays blue.
  • Finished photos stay finished Well-lit strobe photos are recognized as not needing a color fix — the automatic correction leaves them alone.
  • Style presets Natural, Vivid, Subtle, Macro.
  • Fine control Auto strength, water path, red rebuild, neutral midtones and water protection as separate sliders.
  • Analysis readout Shows open water share, color cast, haze and how much red was lost.
