The organisers of the 2017 Sony World Photography Awards, the world's biggest photography competition, have revealed the shortlists for its Professional, Open and Youth competitions. A total of 227,596 images were entered this year, by photographers from 183 countries. The judges have narrowed these down to 10 images in each category. In this gallery, we present a selection of images from the Open shortlist. See the professional shortlist here.

The shortlisted photographers now compete for the latest Sony digital imaging equipment and inclusion in the 2017 awards' book plus cash prizes of $25,000 (about £20,000) for the Photographer of the Year, $5,000 (USD) for the overall Open winner and €30,000 of equipment for the university of the Student Focus winner. All winners will be announced at an awards ceremony in London on 20 April 2017.

The winning, shortlisted and commended images will all be exhibited as part of the Sony World Photography Awards exhibition at Somerset House, London. The large-scale exhibition will open 21 April and will feature rarely seen work by Martin Parr, recipient of the awards' Outstanding Contribution to Photography prize. The exhibition will run in London until 7 May and will then go on a worldwide tour. Exhibition tickets are available at
