We regularly post short Marine Wildlife Videos an Photographs with a short explanation regarding the subject and the technique used to capture the image.

Subject: From pale white to deep purple, the colours of the Indian Doublebar Goatfish (Parupeneus trifasciatus) can change within seconds. These colour alterations seem to be related to the goatfish’s activity of the moment; for instance: they turn pale when resting on the sand.

Technique: It’s always a good idea to integrate close-ups in the final product. It shifts the attention of the subject to the beauty of its details.

Subject: A pair of Tiger Cardinalfish (Cheilodipterus macrodon) meddles with a shoal of Squirrelfish. This Cardinalfish species, one of the biggest of its family, is a predator of small fish. The Squirrelfish are mainly feeding on crustaceans, mollusks, and gastropods and form no danger to smaller fish species. So, any small fish believing to be safe in the vicinity of squirrelfish are hopelessly deceived for the Tiger Cardinalfish, disguised by their red and white stripes mimicking the squirrelfish, do form a thread to them. This form of mimicry where a predator mimics a less dangerous species is called Mertensian mimicry.

Technique: A lot of suspended particles resulting from a few days of heavy rain made the filming conditions difficult. Positioning your video light too close to your objective will generate a lot of backscatter (light reflecting on these particles), positioning your lights too far away will underexpose your subject. With some trial and error I managed to set up the video lights so that the backscatter was reduced to a minimum yet still illuminate the fish enough to bring out the red colour in their scales. Noise reducing software was applied in post-production to reduce the adversity of the water conditions.

Subject: A Black coral bush provides a safe haven for a shoal of Glassfish. These little fish are extremely vulnerable to predation and will therefor always be found close to an area where shelter is provided by nature. Swimming around the bush-like coral colony they will retreat to the safety of the cnidarian at the slightest sign of insecurity.

Technique: A wide-angle scene is in my opinion best filmed with a steady shot. Moving around with your camera will most likely disturb the marine life; fleeing fish won’t make good subjects. I Added the sound of wind chimes in the final product to accentuate the sudden movement of these little fish.
