Picture dated October 23rd, 2018 shows brother and sister Henry (7) and Lily Sales (9) getting in some early practice for the World Puddle Jumping Championships at Wicksteed Park in Kettering, Northants, UK. Organisers have made more puddles than ever before in an attempt to make this year's competition the biggest and best yet. They are also hoping competitors will set a new record for the most people jumping in puddles at the same time. Judges will give scores based on the height of the jump, enthusiasm, distance of splash and stickability (the amount of mud which clings to each competitor). (Photo by Geoff Robinson Photography)

Art director Stephen McMennamy puts photos together to create quirky images for his ongoing project “combophoto’s”. Whether it’s a seagull with an airplane tail or a pair of donut headphones, he jots down his inspirations for each piece on his tumblr. Ever since he got interested in photography through instagram in 2012, he also set up an extra account named @combophotofail, where he shares a look behind-the-scenes on how these images are produced.

Sandrine Kerfante has had a fascination with “doubles” ever since meeting her mother’s twin as a child. In 2012, this lifelong captivation inspired her to create a blog called twin-niwt, which celebrates photographs of doubles in all their forms. “I’m fascinated by the idea of the duo, repetition, symmetry, reflection, mirror games and all the symbolism associated with it”, she says. “I think it’s a topic often present in photography, more or less consciously”.

Luis Hernan was always curious about how wireless technologies like radio are transmitted through the air. So after finishing up his studies in architecture, computer science, and design, Hernan decided to research these invisible signals through a PhD at Newcastle University. Hernan set up a system that turned the wireless signals around him into colourful, ghostlike images using long-exposure photography, allowing people to see the strength of the signals around them.

Born 1938 in New York, Melvin Sokolsky was a major figure in the revival of fashion photography from the 1960s. He was only 21 when he started working at Harper's Bazaar for which he produced the “Bubble” series of photographs depicting fashion models floating in giant clear plastic bubbles suspended in midair above the Seine river in Paris. Alongside his steady collaboration with Bazaar, he also worked for publications such as Vogue and the New York Times.
