These ink-redible, explosive masterpieces are like say-what-you see inkblots tests only in water. The vibrant colors burst from Brian Tomlinsons works, appearing as though they may be coloured ash clouds from an erupting volcano, rather than simply everyday substances. By doing so, Brian challenges viewers to identify what images can be imagined when mixing one fluid with another. In order to shoot the series, entitled Liquid Ink Art, Brain, 40, drops different coloured inks into a fish tank full of water before capturing high-speed shots with a flash. Here: Brian Tomlinsons ink artwork. (Photo by Brian Tomlinsons/Caters News Agency)

Wide-angle category winner. Part of the Illusion by Marcus Blatchford (UK). Location: National Dive & Activity Centre, Chepstow, Wales. “This is the deepest inland dive centre in the UK. The dive plan was to explore the deep end, but this time I dived ‘unplugged’ (without my strobes). With the exception of this change to my camera technique, there were no planned shots I wanted to achieve – just a fun dive with ad-hoc photos along the way. Shortly after this photo was captured, in 6C water and two hours of decompression ahead of us, we turned and started the long ascent back to the surface”.

Water is seen on part of the glacial ice sheet that covers about 80 percent of the country is seen on July 17, 2013 on the Glacial Ice Sheet, Greenland. As the sea levels around the globe rise, researchers affilitated with the National Science Foundation and other organizations are studying the phenomena of the melting glaciers and its long-term ramifications. The warmer temperatures that have had an effect on the glaciers in Greenland also have altered the ways in which the local populace farm, fish, hunt and even travel across land. In recent years, sea level rise in places such as Miami Beach has led to increased street flooding and prompted leaders such as New York City Mayor Michael Bloomberg to propose a $19.5 billion plan to boost the citys capacity to withstand future extreme weather events by, among other things, devising mechanisms to withstand flooding.
