Sharks are baited, but since these are wild animals, they can be unpredictable. In addition, although the most common species seen in California’s waters are blue and shortfin mako sharks, other species, including great white sharks, can show up. It is imperative that shooters pay attention to the dive operator’s instructions first – and their camera second. • Sharks are fast-moving, especially shortfin mako sharks – the fastest species of shark. To shoot makos, use the fastest speed to which your strobes will sync, and do not deviate (adjust your ISO before you slow your shutter speed)! Watch your autofocus carefully: Some cameras may struggle with focus when faced with such a fast subject – in a pinch, try to focus on an area of contrast, such as teeth or gills. Make sure your dome port is clear of bubbles, and don’t forget that when using a super-wide lens, your subject is closer than it appears through the viewfinder.
