Gullfoss in Iceland is a spectacular waterfall. To emphasize its power I chose to photograph it as it made its journey over the final cliff and dropped into a perpendicular chasm. Gear: Canon 5D Mark III, EF 24-105 f/4L IS. Shot @ f/5.6, 1/200 sec, 47 mm and ISO 500. Post processing: Photoshop CC, selective adjustments of exposure and contrast using masks, texture and detail added with Topaz Adjust and converted to black and white using Nik Silver Effects Pro.
