Seljalandsfoss is located between Selfoss and Skogafoss on the Southern Ring Road (Iceland’s main highway) down to Vik. The picturesque waterfall plummets 60 m (200 ft) to a deep pool below. Visitors can even hike around the pool to the back of the falls for a unique perspective many of us will never experience when viewing a waterfall.
A little further to the west there are several other falls, among them the interesting Gljúfrabúi which is partially masked by its own canyon.
To get this stunning capture of the waterfall, photographer Howard Ignatius hiked to an elevated position. On his Flickr description page, he says combined 5 images in Photoshop CS6 and post edited in Lightroom 4.2 using with a 16-stop dynamic range. You can see more from Howard on Flickr.
