Waves like these can be very dangerous be careful.Taken at Middle Cove Newfoundland. Taken from over 600 feet away with a Tamron 150x600mm Super Telephoto Zoom Lens, Nikon D810, Dimensions 6799 x 4619, Size 11.3 mb F/8, ET 1/250 sec, Iso 200 and FL 250 mm. I estimate the height of this big fellow at around 60 to 65 feet. The most fascinating thing for me is the Blow Back which is when the wave hit's the cliff wall, it mushrooms straight up and rebounds off the wall actually going backwards.
