The set was built and checked against 141 real clips. 121 of them came from a dive library, shot on real dives in blue, green and fresh water.
Every filter was checked for crushed blacks and colour push before it shipped. That is the whole claim. Nothing here is tuned on stock footage.
Play a clip to see the ramp. Shallow steps do less, deep steps do more.





The app picks a group and a step for you. The table is here so you know what it picked from.
| Group | Steps | When to use it |
|---|---|---|
| Off | 1 | The clip as the camera recorded it. Used for checking what changed. |
| Blue water | 6 | Tropical and open ocean dives. Steps run from shallow to deep, pick the one that puts the red back without going pink. |
| Green water | 5 | Coastal and temperate dives with plankton in the water. Steps run from light green to heavy green. |
| Fresh water | 3 | Lakes, quarries, springs and cenotes. Lower steps for clear fresh water, higher for murky. |
Deep water clips lose shadow detail fast. Each step was measured so the dark parts of the frame keep their detail.
Putting red back is easy to overdo. Each step was checked so the water stays water and skin stays skin.
