Snorkeling video color correction
Snorkelling clips have their own problem: not deep blue, but low contrast, floating particles and a milky cyan cast. Standard dive corrections turn that into dark, crunchy sand. This tool detects it and treats it differently.
What is different about shallow water
At one to four metres most colours are still there, but sunlight scatters off sand, silt and plankton. The image loses contrast rather than colour, and a strong red compensation plus contrast stretch – right for a reef at fifteen metres – pushes it into orange sand and purple shadows.
The hazy-water preset
- Detected automatically from the low tonal range of the frame, and shown as "Shallow / hazy" next to the file.
- Gentler red compensation (about 60 % of the reef preset) so skin and sand stay natural.
- Contrast cap so the stretch never turns milky water into black shadows.
- Saturation guard that limits how much the overall saturation may rise.
If a clip is detected as hazy but you would like more punch, set the scene to Reef manually and lower Strength to taste – the preview updates instantly.
Tips for better snorkelling footage
- Shoot with the sun behind you; backlit particles are what makes water look milky.
- Get close – a metre less distance removes more haze than any correction.
- Keep the camera still for a second at a time; the temporal smoothing then has an easy job.
Why snorkelling footage looks milky
Three things happen at the surface that rarely happen at twenty metres. Sunlight comes and goes with every wave, so the exposure breathes. Sand and plankton stirred up in the shallows scatter light between you and the reef – that is the haze. And your own fins kick up more of it. The result is low contrast rather than a strong blue cast, which is why the usual "add red" fix makes it look worse: more red in a hazy frame just turns the haze pink.
Habits that help
- Shoot with the sun behind you and avoid filming straight into the surface – the sparkle saturates the sensor and nothing can bring that detail back.
- Hold still for a second before you press record. The cloud you kicked up settles surprisingly fast.
- Leave the red filter at home. Filters are made for depth; in a metre of water they add red that was never missing.
- Phones: lock exposure and focus (long-press on the screen) before the phone goes in – a housing's touch screen rarely works under water.
Frequently asked
Why does my snorkelling video look worse after other apps?
Most tools apply a dive-strength red boost and contrast stretch. In shallow, hazy water that over-corrects. The hazy preset here is specifically tuned on snorkelling footage from the UAE and the Red Sea.
Does it work with phone clips from a snorkel trip?
Yes – iPhone and Android MP4/MOV, including 4K and HEVC.
Turtle from above in bright sand – why so dull?
Top-down shots over bright sand have very little tonal range. Try the Reef scene at 70 % strength for a bit more contrast.
