Wide-angle category winner. Part of the Illusion by Marcus Blatchford (UK). Location: National Dive & Activity Centre, Chepstow, Wales. “This is the deepest inland dive centre in the UK. The dive plan was to explore the deep end, but this time I dived ‘unplugged’ (without my strobes). With the exception of this change to my camera technique, there were no planned shots I wanted to achieve – just a fun dive with ad-hoc photos along the way. Shortly after this photo was captured, in 6C water and two hours of decompression ahead of us, we turned and started the long ascent back to the surface”.

A kingfisher dives into the leafy water of the River Alde near Rendham, Suffolk in the second decade of November 2022 and catches two fish. Kingfishers must be able to see the fish they want to catch before making their dive, so for this bird to be successful when leaves covered the surface of the water shows its true skill for survival.

The incredible detail in each photo is thanks to Jordi Benitez Castells, years of experience taking photos while diving. Jordi, 40, from El Vendrell, Spain, was in Catalunya when he took the photos and managed to get the snaps at about three metres below the surface in most cases. While he works full-time in a bank, Jordi dons his wetsuit out of hours to go diving and uses a Canon 7D to get his shots. Here: One of the beautiful jellyfish. (Photo by Jordi Benitez/Caters News)
