Subject: The Striped Catfish (Plotosus lineatus) is one of the very few catfish species that is found in saltwater. Schools of these fish are known to swim up rivers on Africa’s east coasts. The spines of the first dorsal and of the pectoral fins are venomous, and can be lethal, a good reason for the Convict Blenny (Pholidichthys leucataenia) to mimic this species.
Technique: To enhance the visibility of these frantic moving little fish (when they grow big they become nocturnal and are therefor seldom seen) we played around with the contrast; we darkened the brownish/black and made the white more clear. Often it is nice to remove the attention of the subject’s surroundings so we slightly desaturated the reddish algae.
