For centuries the Highlands peoples of Papua New Guinea fought over land, women and pigs. Sorcery and battle skills could elevate a clan to Bigmanship, where the bigger the “presentation”, the bigger the man.

These kaleidoscopic images are the work of one persistent photographer’s efforts to capture vibrant hues at the exact moment a wave breaks. Ryan Pernofski‘s stunning shots feature brilliant yellows, reds, blues and purples as an array of sunlight hits the water at the perfect time. What’s even more impressive: Ryan, a 27-year-old Australian, began shooting his popular masterpieces without using a professional camera, taking his iPhone out into the water instead. Ryan began experimenting with this method in 2012, using an underwater housing to protect his phone, as he could not afford a professional camera. (Photo by Ryan Pernoski/Caters News Agency)

The Tree Projects team spent 67 days documenting one eucalyptus regnans in the Styx valley of Tasmania. Using a combination of tree-climbing and elaborate arboreal rigging techniques, they produced an intimate portrait from an impossible perspective of one of the world’s largest individual flowering trees, which goes by several common names. These photos document the process that resulted in an extraordinary ultra high-definition photograph. Here: Haley nears the top of the tree. (Photo by Steven Pearce/The Tree Projects/The Guardian)
