This photo was not applied HDR technique. When applying appropriate filters, we could get a successful shot. Additionally, to control overall sharpness, the maximum f-stop that I usually use in landscape/seascape photo is f11.0 as to avoid the diffraction. In this photo, I focused about 1.2-1.5 m. from camera that was usually the hyper-focus of the lens, 16-35mm.
Finally, I set up my camera on tripod in quite low angle that about 4-5 inches above the water level. I needed to clean the filters several times before getting a satisfied shot from this scene. My camera was partly watered, but everything seemed alright.
