Another from here down under. Breaker Bay is on the south coast of Wellington and about 10 minutes drive from my house. It must be a geologist's heaven as it's just all rocks, boulders and rock formations.
Anyway! How could this have been shot (and processed?) better?
What I have noticed in many of my shots is I'm probably trying to fit too much into the image and perhaps need to simplify.
Composition OK - viewing point slightly to the left might have improved it, with continuity of water past the big rock, and looking more along the rut than across it.
Red or neutral grad to lighten up the rock.
DOF seems OK, but a view camera would have helped, and given you the option of a faster shutter speed.
A Longer lens would have made more of the distant rocks, and a much longer lens could produce a nice picture, mostly of the sea... Landscapes are not all about wide angles!
