The coast is a difficult subject, and it is difficult for one simple reason: it contains more contrast than almost any other landscape in Britain. A bright sky, dark wet rocks and a sea that reflects both at once will confuse even a very good light meter. Before you start composing, decide what matters most in the frame. If the sky is full of drama, expose for the brightest clouds and let the foreground fall into shadow. If the foreground is the story — a rock pool, a piece of driftwood, a band of shingle — expose for that and accept a blown-out sky.
A polarising filter is the single most useful accessory at the seaside. Rotated correctly, it cuts the glare bouncing off wet sand and water, revealing colour underneath and deepening a blue sky. Be careful with very wide lenses: the effect can vary across a large expanse of sky and produce an uneven, patchy look. A graduated neutral density filter helps balance a bright horizon, though on a moving sea the transition line can become obvious, so use it with judgement.
Coastal photographers talk about golden hour so often because it genuinely transforms the scene. In the hour after sunrise and the hour before sunset, the sun sits low, light travels through more atmosphere and arrives warm, soft and directional. On a beach this means long shadows across ripples in the sand, warm highlights on wet pebbles and a sky that does the hard work for you.
Timing matters as much as technique. Check the tide table for the stretch you plan to visit — it is published by local harbour authorities and often posted at the slipway — and think about which state of tide suits your shot. A low tide exposes rock pools, wet sand and patterns that vanish at high water; a high tide can bring waves close to a headland or pier and give you drama you could not otherwise reach. Arrive at least forty minutes before you intend to shoot, walk the location, and find two or three compositions so you are not rushing when the light peaks.
The rule of thirds works beautifully by the sea, but not because it is a rule. It works because putting the horizon on the upper or lower third of the frame forces you to decide what the photograph is actually about. Horizon high, and the foreground — sand, stones, pools — dominates. Horizon low, and the sky becomes the subject.
What you should almost never do is drop the horizon through the dead centre by accident. The one reliable exception is a reflection shot, where a still pool or a wet beach mirrors the sky above and a symmetrical composition feels calm and deliberate.
The sea is in constant motion, which means shutter speed becomes a creative choice rather than a technical one. A fast shutter speed of around 1/500 second or quicker freezes spray and the crest of a breaking wave, capturing texture and energy. Around 1/2 to 4 seconds turns moving water into something smooth and milky, which suits rocky coves and long shorelines. Exposures of ten seconds or more, usually with a neutral density filter, blur the sea into something almost abstract and smooth out passing clouds.
Anything slower than about 1/30 second needs support. A tripod is worth carrying even on a short walk, and pushing the legs into damp sand gives you a much steadier base than you might expect. A remote release or the self-timer removes the shake caused by pressing the shutter.
Sea air is corrosive and sand is abrasive, and between them they will quietly ruin equipment that is not looked after. A few habits make an enormous difference.
Good coastal photography and coastal conservation go hand in hand. The places that make the best pictures are usually the ones that are most fragile, and a crowded clifftop or a trampled dune system suffers for every extra pair of boots.
Stay on established paths, particularly around sand dunes, where a single misplaced step can damage vegetation that takes years to recover. Keep a generous distance from seals hauled out on rocks or beaches — if an animal raises its head or moves because of you, you are too close — and give nesting birds on cliffs and shingle a wide berth between spring and late summer. Take everything home with you, including the pebbles and shells that look so tempting as a foreground prop, and leave the beach as you found it.
The best coastal photographs come from patience rather than equipment: knowing the tide, waiting for the light, and treating the place itself with care. Do that, and the landscape will reward you again and again.
