An alternative can be to make some similar looking objects that are like fake coral blocks and use a boat to sumerge them in the sea and compare the corrected photos with the photos taken in air before. (The wet surfaces have a different look, and it would be important to use a diffuse light instead of direct sunlight, and perhaps other technical problems for the comparison.)
- dghughes 7y agoI'd assume that's the point of the colour reference card. You know what the colours should look like when not under water.
