In this Tuesday, September 12, 2017 photo, Amornrat Simapsaisan, a local shop manager, watches before she ate watermelon salad with bamboo worms, at Inspects in the Backyard restaurant, Bangkok, Thailand. Tucking into insects is nothing new in Thailand, where street vendors pushing carts of fried crickets and buttery silkworms have long fed locals and adventurous tourists alike. But bugs are now fine-dining at the Bangkok bistro aiming to revolutionize views of nature’s least-loved creatures and what you can do with them. She tucked in quite happily to her watermelon and cricket salad on a recent evening. “It’s tasty. It’s munchy”, she said. (Photo by Sakchai Lalit/AP Photo)

“Are you here for the Winery Tour?” This is a Western Grey Kangaroo caught lounging in the wineries of the Adelaide Hills in South Australia. This past Autumn has been a spectacular time for wildlife viewing and I got lucky to spot this guy while mountain biking in the hills. Such a funny stance it just begs the question... Have you been drinking? ...and or... Are you here for the Winery Tour? Such a spontaneous moment I figured it would be perfect for an entry. I hope you like it! Cheers. Photo location: Adelaide Hills, South Australia, Australia. (Photo and caption by Greg Snell/National Geographic Photo Contest)

Hedi Xandt imagines impressive sculptures. Mixing styles and materials with talent, the artist invites us to discover his dark and intense universe.

We – Verena Popp-Hackner and Georg Popp - are professional landscape photographers. While we are based in Vienna/Austria, running our own (rights managed) image library and a small but fine photo-gallery. Photographing our tiny country Austria, with all it's culture and nature, canoeing it's rivers or lakes and hiking the Alps is our profession but our photographic “backyard” includes the rest of the planet as well. We use analog large format cameras almost exclusively for our landscape work, shooting on 4x5” sheet film, to provide clients with the maximum of print-sharpness and details and unsurpassed clarity and depth of focus.

Praia du Forte, Bahia. “This was the lead picture for a National Geographic story on Bahia, because it was both mysterious as well as a “geography” picture showing where the slaves arrived from Nigeria. Beach pictures seem like they should be easy to take, but for me they are actually quite difficult. Too easy to fall into cliche. When I saw the kid coming on the horse, I quickly ran to see if I could make something with a woman in a bikini that was not a bikini shot”. (Photo by David Alan Harvey/The Guardian)
