LUTly Dive is an iPhone app for divers. It works on GoPro, Sony, DJI and iPhone clips. It works out the camera and the water on its own. Everything runs on the phone and nothing is uploaded. Trying it is free.
Each clip below came off a dive card. Play one to see what the water took and what came back.





Red light stops first, in the first few metres. Orange goes next, then yellow. Green hangs on longer and blue goes deepest of all.
That is why a reef at 18m looks blue and flat on the card. It is also why the same clip looks washed out even when the visibility was good. Nothing was wrong with your camera.
The app reads the file and works out which camera shot it. It then reads the picture and works out how deep you were and what the water is doing.
It picks the right fix from that on its own. You do not choose anything. If you want to move it, you can, but you do not have to.
A dive gives you twenty clips, not one. Bring them all in at once and they sit in a tray on the phone.
The app handles the set together so the clips match each other. You can step through the tray and check them one by one.
The app is free to download and free to try on your own clips. You see the finished result before you pay.
Paying is required to save the finished video out of the app.

An iPhone app that puts the colour back into dive footage. You bring in a clip, it works out what the water took, and it gives you the clip back looking like it did to your eyes.
GoPro, Sony, DJI and iPhone clips are all read directly. Clips from other cameras still work, the app treats them as standard footage and fixes the water.
