That flat ocean sunset is not a creative failure; it is a metering failure baked into your camera. The sensor sees blazing sky and near-black water, then exposure metering tries to land in the middle, compressing dynamic range until the glow that drew you to the horizon is mapped into a polite midtone.
The harsh truth is simple. You are telling the camera to erase the drama. Evaluative metering, matrix metering, whatever the branding, samples the whole frame and protects an average luminance value, so highlight detail in sunlit cloud edges gets clipped or dragged down while the sea muddies toward gray, all in the name of a smooth histogram.
The smarter move is surgical. Meter directly on the bright cloud rim, with spot metering or a tight partial pattern, then lock exposure and reframe so the sunlit edge defines your reference point. That shifts the exposure value toward protecting highlights, lets the water fall into deeper shadow, and restores the high local contrast your eyes remember at the horizon.
