People stop to look at the thousands of so-called “love locks”, or “love padlocks”, that hang from a fence across the Hohenzollernbruecke bridge on September 13, 2011 in Cologne, Germany. Love locks are a growing phenomenon in cities across Europe and are meant by the couples who leave them behind as a symbol of their powerful and undying love for one another.

Ace Wu searches the deep to photograph stunning underwater creatures. Against their predominantly black backdrops, Wu’s breathtaking subjects glow with sublime vibrancy.

New Zealand photographer Niki Boon captured her children, who are growing up with limited electronics, in the photo series “Childhood in the Raw Photos”. Niki Boon began taking photos as a hobby while she was working as a physiotherapist in Scotland. However, the New Zealand native found her interest in the art waning while she travelled, and it wasn’t until she had returned home and started raising a family that her passion was rekindled. “Childhood in the Raw”, an ongoing photo series of her four children’s technology-free life on her 10-acre property in New Zealand, is the perennial fruit of this passion.

The unromantic gypsies. Children boxing in a gypsy camp in Kent, England on July 1, 1951. Like all boys these gypsy lads like to try their hand at boxing. Encouraged by their friends they fight it out on Corke's Meadow. Few Romanies now live a life of wandering romance. Most are like the three hundred squatters of Corke's Meadow, Kent, which is part of a “gypsy problem” that involves about 100,000 today. Of those about 25,000 can be rightly called gypsies, the rest are Mumpers and Posh-rats and Hobos. Corke's Meadow has both kinds. “Picture Post” cameraman Bert Hardy photographs the Corke's Meadow gypsies in their encampment. (Photo by Hulton-Deutsch Collection/Corbis via Getty Images)
