Slow shutter speed for the smoothing effect, focal point on the rocks at stopped down aperture to keep it good and sharp while smooth at same time, around 1/10 sec @ f/16 iso 200, then in LR I just downed exposure a bit (I over exposed a bit on purpose to get this effect later in pp when I brought it back down...helps on the noise control), then upped clarity a ton and adjusted lights/shadows options in tone curve section for desired contrast effect. I think that's all. lol. oh, and upped vibrance to around 30 or so to bring out blues more.
lots of thought/effort in a silly photo, but it's good practice for later this season when I make it out to the coast.
