Underwater photography is tough, and, when you're dealing with something less than Caribbean-clear blue seas, finding the right lighting can be near-impossible. Fujifilm's Remora looks to make things a little easier, offering a 60 degree beam of light with a guide number of 20, so it's bright enough even for nighttime cuttlefish documentaries but can be dimmed to save the retinas of sensitive cephalopods. Four AA batteries give you 240 flashes at a depth of up to 180 feet, but at £229 (about $370) only the most serious rebreathers need apply.Filed under:
