Lush expanses of perfectly manicured green. Colorful crowds of onlookers.

That’s the typical view at East Lake Golf Club during the PGA Tour Championship.

While photographer Ben Gray was capturing traditional images during this year’s tournament, he decided to take a different view — infrared. He used a digital camera modified to record only infrared light. The images were then processed using a technique that swapped the color channels to return the skies to blue.

These infrared photos capture invisible light and turn green foliage and most clothing to a ghostly white, causing the familiar scenes of a golf tournament to turn into a surreal, snow-covered wonderland.
