@njeneb: Yes, a distribution shader to get more foam on the higher waves. The coastal waves were distributed by a quick coastal swoop of the painted shader. I tried for many hours to use the 'snow effect' to get real foam spouting up against the cliffs, but the settings had to be so precariously precise for a realistic effect, that I gave up. It should work though. I did add a small band of broken up white at sea level to get some water running down the cliff near the waves, as well as a higher band with a reflective shader, of course, and a color adjust.
@schmeerlap: there was no post work on the sea, the foam came from a fractal. The only post work was duplicating the whole image layer in PS, setting it to bleach, diminishing it's percentage to 50%, lowering it's tonal curve (S), and putting them together (CTRL-E). Gives a slight haze around the lights.
