Aurorae category runner-up: Lone Tree under a Scandinavian Aurora by Tom Archer (UK). The photographer decided to explore the area around the hotel on a very crisp -35C evening in Finnish Lapland. When he found this tree, he decided to wait for the misty conditions to change and could not believe his luck when the sky cleared and the aurora came out in the perfect spot. Archer spent about an hour photographing it before his camera started to lock up because of the harsh conditions, but by then he was happy to call it a night.

British Waters Wide Angle category runner-up. Grass snake swimming along a garden pond by Jack Perks (UK)in Nottinghamshire, UK. “I’m always on the lookout for unusual freshwater subjects and grass snakes are a species I’ve been after for years. I was told about a pond where the odd grass snake hangs around the lilly pads for frogs. I put my drysuit on and got into the water and could see one slithering along the surface. Slowly making my way towards it with my head only just poking above I got the spilt shot”. (Photo by Jack Perks/Underwater Photographer of the Year 2019)

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”.

Grand prize winner: environmental photographer of the year 2023; also 1st place in the humanity v nature category; and winner of the 2023 public award. Lopé national park, Gabon, 2021. An angry elephant tries to defend itself after it was hit by a train that crosses paths the animals use within Lopé national park. Park officials decided the elephant was too severely injured to be saved. After it was killed, the park director distributed the meat to local people. As the forest loses its carrying capacity to sustain its megafauna, this kind of human-wildlife conflict is increasing. (Photo by Jasper Doest/Environmental Photography Award)
