Subject: The Whiteblotched Grouper (Epinephelus multinotatus) can grow up to 1m/3ft in length. The adults of this species prefer deeper water while the juveniles are more likely to be seen in shallower areas.
Te chnique: On the day we filmed this animal the water was full of suspended particles. In post-production a noise-reducing generator removed the vast majority of this marine snow as it is often called. Because grainy footage (often the result of a too high ISO) and marine snow are look-a-likes to the editing software, these generators can be used to remove the unwanted particles, often with surprisingly good results.
