Subject: On a sandy slope somewhere in the Bali Sea a Hell’s Fire Anemone (Actinodendron arboreum) is providing shelter for a school of little Cardinalfish. These anemones have a very potent sting, hence their name, but will rather retreat into the sand when disturbed.
Technique: I almost never use my GoPro due its limitations in settings but sometimes on rare occasions the use of these little cameras can be beneficial. I positioned the action camera on a stand and left it alone for several minutes before I collected it to retrieve the footage. When filming this scene I took the direction of the current into account. Fish almost always face the current and thus by positioning yourself facing your subject in a +/- 45° angle you will get the best possible images of a current swept scene.
