Subject: A school of snappers faces the very light current in Mauritius. Those who watch carefully can distinguish two different species; the Bluestripe Snapper (Lutjanus kasmira) with a dark band in between its eye and snout and the Bengal Snapper (Lutjanus bengalensis) who is completely white from its lowest horizontal stripe down. Different species that look-a-like regarding colour and markings often congregate in big schools.
Technique: Big objects like in this case schooling fish are always difficult to illuminate completely with standard video lights. The use of an orange filter as an alternative is to be considered in certain circumstances. In post-production the yellow of the snappers and the blue of the ocean were a bit saturated in order to make the image more vibrant.
