Ra Paulette is an American cave sculptor based in New Mexico who digs into hillsides to sculpt elaborate artistic spaces inside mountains. Reviewer Martha Mendoza in the Los Angeles Times described the caves he created as shrines, as hallowed places, a “sanctuary for prayer and meditation” while others describe the caves as works of art. The caves are finished with “scallops, molded curves, smooth ledges, inlaid stones, narrow pods and crusty ledges”. His caves attract visitors worldwide.

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.

Have you ever heard of a phenomenon called the Uncanny Valley? Illustrations created by Swiss illustrator Christo Dagorov show how horrible something may look when it’s a hair’s breadth away from looking human. In his illustrations he combined the shape of human lips with trees, buildings, and even human bodies, making it look from a distance as if the lips were horribly deformed by some unknown disease. However, after a while you make out the shapes, yet the feeling of uneasiness remains, making you shiver from unsuppressable disgust. (Photo by Christo Dagorov)

The mystifying flow of motion. We can rarely appreciate its beauty. Though there are ways to capture it on film, allowing us to marvel at its complexity. Stephen Orlando is a photographer who takes pleasure highlighting the magnificence of aquatic sports by using the brilliance of light. The beauty of the images that he creates comes not only from the composition of the photo, but also from the way Stephen managed to show the color transitions between each stroke of the kayaker. Even the rapids do not stand in the way of the marvelous dance of light. (Photo by Stephen Orlando)

A not-so-famous photographer Robert Jahns can do impossible things with common photos. He takes two pictures and joins them into a single composition. Thanks to this creative idea, which is based on the combination of contrasts, ordinary photos become interesting and attractive. Jahns combines several pictures into one seamless scene. A leafless crown of the tree, layered onto deer antlers, creates a real and natural continuation of the deer`s head. Likewise, a rollercoaster with an overview of the city frightens us by being very realistic. (Photo by Robert Jahns A.K.A. Nois7)

The Vietnam Slide Project was created by photo editor Kendra Rennick, who began collecting photo slides after a close friend lost her father, a Vietnam veteran. Her friend found a box of slides that her father had taken while in Vietnam and from there Rennick has continued to collect photographs that Vietnam veterans took during their tours of duty. Here: A photo taken from the collection of D.Thornton, who served in the First Air Cavalry division of the United States Army. (Photo by D.Thornton/The Vietnam Slide Project)

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”.
