Wow, love the photo! Slow shutter speed really does the trick. It seems that the water is almost rushing out of the picture straight at you. Love the forground fills 2/3 of the whole photo, very powerful indeed. Good work.
Thank you! I pretty much had the tripod in the water and down at a very low level and waited patiently for the swell to fill between the gaps in the rocks. This is 1 of over 1000 shots taken, so many different variables but liked this one.
