There is nowhere quite like the British shoreline in wild weather. Winter gales off the Atlantic, a spring tide running up a Cornish beach, spindrift blowing over the pebbles at Aldeburgh — it is exactly the drama most of us went into landscape photography to capture. It is also, gram for gram, one of the most hostile environments you can expose a camera to.
Sea spray is not just water. It is a fine aerosol of salt, and when it dries on your lens, sensor filter or hot shoe, it leaves crystals behind. Salt is hygroscopic: it pulls moisture out of the air and holds it against metal and electrical contacts, which is how a perfectly good camera ends up with a corroded hot shoe and a misty viewfinder. Sand is worse in a different way. Those grains are essentially ground quartz, and they work their way into zoom barrels, focus rings, tripod leg locks and battery compartments, where they grind away at anything that moves.
Add the third threat — the sudden wave — and you have a situation where a bit of preparation saves a very expensive mistake. A set of larger waves can arrive with far more reach than the ones before it, and a rising tide on a flat beach can put water at your feet in seconds. The good news is that every one of these problems is manageable with inexpensive, lightweight kit.
Start with how much protection the situation actually demands. If you plan to shoot in the surf zone, or you are working from rock ledges where spray is constant, a proper underwater housing is the only honest answer. Test it empty first, inspect the O-ring for grit and hair, and rinse the outside in fresh water before you open it. A housing that has been sitting in a cupboard for a year is not a housing you should trust.
For most coastal work, though, you do not need to go that far. A well-fitted rain cover over the body and lens, cinched down with the lens hood fitted, keeps the worst of the spray off. A clear or UV filter on the front of every lens is the cheapest insurance you can buy — let the salt land on a piece of glass you can replace for the price of a pub lunch rather than on a front element you cannot.
Condensation is the quiet killer of coastal photography. You are on a cold beach, you finish shooting, you get back to a warm car or a heated cottage, and the moisture in that warmer air condenses on the coldest thing in the room — your lens elements and your sensor.
Silica gel sachets are the simplest fix. Keep a handful in your bag, in your dry bag and in your storage box at home. Rechargeable sachets are worth the extra few pounds because you can dry them out on a radiator and use them again indefinitely. When you move between temperatures, seal the camera in a dry bag or zip bag before you go inside and let it acclimatise for half an hour.
Never change lenses outdoors in coastal conditions. If you must swap, do it in the car with the doors shut and the heater off, or inside a large dry bag with your hands and the lens inside the opening. One grain of windblown sand on a sensor is a tedious afternoon with a swab.
A camera rucksack with a pull-out rain cover is not waterproof; it is showerproof at best. For coastal work, think in layers. A roll-top dry bag inside your existing rucksack gives you genuine protection for very little weight, and keeps working even if the outer bag gets soaked.
The way you carry and park the bag matters as much as the bag itself. A chest harness keeps your kit high and dry when you are scrambling over wet rocks, and it means you can get to a filter without putting anything down on the sand. When you do stop, hang the bag from the tripod hook rather than resting it on the beach, and be careful with zips — sand trapped in the teeth will chew through them within a season. A soft brush or an old toothbrush clears them out nicely at the end of the day.
Half of gear protection is simply not being in the wrong place. Check the tide table, the swell forecast and the wind direction before you leave the house. An onshore wind means spray is being driven straight at your front element, so position yourself with the wind at your back where the composition allows.
Waves arrive in sets. Watch for several minutes and count the pattern, because the biggest wave in a set often follows a lull that tempts you to step closer. Never turn your back on the sea, and treat wet rock ledges and the leading edge of a flat beach as places to visit briefly rather than to settle into. If you are shooting long exposures on a tripod, keep the legs out of the water where you can — salt in twist locks is a nuisance to clean — and wipe the feet down afterwards.
What you do in the first hour after a coastal shoot determines whether the damage is cosmetic or permanent. Wipe the body and lens with a microfibre cloth very slightly dampened with fresh water, then dry everything thoroughly. Rinse the outside of any housing, the tripod feet and the outside of your bag under a lukewarm tap — never the camera itself, and never with a hose at pressure.
Do all of this as a habit and the coast stops being a risk and starts being what it should be: the most rewarding landscape classroom in the country. Take the weather seriously, protect the small things, and you will come home with beautiful files instead of a repair bill.
