The 2018 Sony World Photography Awards is one of the world's leading free photography competitions. Each week we receive thousands of great entries, but as well as featuring some of our favourites from the current competition, each Thursday we are looking back over the last three years and choosing the best images from across a range of categories.
This week we take a look at some of our favourite commended, shortlisted and winning Enhanced photos...
