The fourth annual BigPicture Natural World Photography Competition aims to celebrate the diversity of life on Earth, and encourages people to protect and conserve it. Here: “The Salmon Catchers”. Terrestrial Wildlife. To capture this view of a mother grizzly bear and her cub, photographer Peter Mather set up a camera trap on a log that he knew the bears tended to traverse while fishing for salmon, in the Yukon River watershed in Canada.

Jenny Odell repurposes online imagery mostly from Google Maps, but also from YouTube, Craigslist, and other sites. In her “Satellite Collections”, for example, she incorporated aerial views of swimming pools, basketball courts, parking lots, and other recognizable structures, seen from space. Her more recent series, “Satellite Landscapes”, includes painstakingly isolated Google Maps imagery of oil refineries, wastewater treatment plants, solar farms, etc. This work is meant as a reminder of our physically determined and vulnerable existence, since we depend on many of these things for survival and maintenance of our way of life.

“Banksy is an pseudonymous England based graffiti artist, political activist, film director and painter. His satirical street art and subversive epigrams combine irreverent dark humour with graffiti done in a distinctive stencilling technique. Such artistic works of political and social commentary have been featured on streets, walls, and bridges of cities throughout the world”. – Wikipedia

The exhibition called “Banksy versus Bristol Museum” is one of the largest single collections of the artist works and was organised under tight security and installed in just 36hrs with only a handful of museum staff aware it was even happening. Banksy, whose real identity remains a mystery, is said to hail from the Bristol area, and claims that hosting the exhibition in the city is his way of thanking the city for his early street art career.
