I made this image a couple of weeks ago at Garrapata State Beach in the evening. The the ocean wasn't as turbulent as the week prior, I still saw powerful waves pound the gigantic boulders that are strewn all over the area.
Successfully making an image like this one requires getting just the right shutter speed. If its too fast, you don't get those long streams, if its too slow the water becomes too smooth and that feeling of power gets lost. Over the years, I've had to do a lot of experimenting to get a feel for what shutter speed I need for a particular effect and taking into account factors like the speed at which the water is moving. Timing is obviously another critical element but with the low lag of modern cameras, it isn't too difficult to manage. Composition is the last critical element since the impact of the wave isn't in the frame when you are composing, requiring you to imagine how big it will be and where it will be in the frame. If you go too tight, the full water explosion would be captured, too loose and it will require too much cropping in post.
