The TransNatura 2026 International Nature Photography Contest is inviting photographers worldwide to submit their best wildlife and nature photographs. Now in its 13th edition, the competition is organised by the VADON Association in Sfântu Gheorghe, Romania, and focuses on photography that documents the natural world and encourages its conservation.

There are two categories: Wildlife and Nature and Landscapes. The Wildlife category covers animals photographed in their natural habitats, from close-up portraits to action shots and animal behaviour. Nature and Landscapes is dedicated to scenery, forests, rivers, plants and natural phenomena, and does not accept photographs featuring animals. Images of captive wildlife are also excluded, and photographers must avoid disturbing animals or damaging their habitats.

Photographs must be submitted as JPG files in RGB colour space, with a minimum of 3,000 pixels on the longest side. Standard adjustments to exposure, colour and contrast are allowed, but substantial changes to important elements of an image are prohibited. Entries must be free of watermarks, signatures and text. An international jury will assess the photographs from 21 to 30 November 2026, with the results announced on 22 January 2027.

Entry fee: The first three photographs are free to enter. Each additional photograph costs €5.
