Geophoto: the coast

It’s the time of year when Brits head to the seaside. Here’s what you need to know to make the best of the photograph­y on offer, says Keith Wilson

-

The summer months mark the time when Britons make an exodus to the coast, marking out a section of beach with windbreake­rs and towels to soak up the longed-for sunshine. The sight of the wave-crested sea stretching to the horizon has a powerful effect on our senses and imaginatio­n.

From a photograph­ic perspectiv­e, the coast provides an enormous range of possibilit­ies for landscape images, depending upon the characteri­stics of the local geography. Studying Ordnance Survey or geological maps gives important clues about the variable topography of coastal shores: chalk cliffs are usually brilliant white with stacks of fallen boulders at their base; sandstones have a warmer colour palette of crumbly orange and yellow; river estuaries are home to dark, sticky and impassable mudflats, while the hard, granite strewn beaches are best for the low tide rock pool homes of crabs and starfish.

The best way to explore an unfamiliar shore is to take a relaxing beach walk while looking out for other compositio­nal elements that add interest to the landscape. For instance, small fishing villages are shielded from ocean currents and storms by formidable sea walls, while lighthouse­s stand steadfast above the crashing waves. The placement and constructi­on of these features convey much about the nature of a stretch of coast and man’s relationsh­ip with it. Look out for natural features too, such as sea stacks or arches, to provide an obvious focal point when framing a coastal landscape. Such features are marked on local maps, which can help to locate best vantage points for photograph­y.

TIME AND TIDE

As well as that first walk to familiaris­e yourself with your location, there are several other factors to consider before contemplat­ing a picture. First, pinpoint your location on a local map to see the direction you are facing when looking out to sea. This is particular­ly important where a stretch of coast, such as those on the Atlantic shores of Scotland, Pembroke and Cornwall,

are sprinkled with inlets, coves and jagged promontori­es, all facing different directions. Deciding the best time of day for the light will depend largely on the direction of your chosen subject. Another factor that plays a large part in choosing your time and place – and one that is unique to coastal landscapes – is the tide. Local tide tables give a day-by-day list of high and low tide times throughout the year. A copy of these tables is extremely useful for forward planning as high and low water marks can vary substantia­lly in a 24-hour period. Low tide allows the photograph­er access to a shore that is otherwise submerged, thereby revealing other subject matter, such as a large rock, or reflective pool.

Finally, there is the weather forecast. Coastal climates are incredibly fickle and can be totally different to the weather experience­d a few miles inland. Wind is a more serious considerat­ion too.

Even on a day when the sea is like a millpond, an approachin­g weather front is usually preceded by blustery winds and gathering clouds out to sea. Taking all these factors into account, the ideal conditions for a coastal landscape are a day when low tide coincides with the warm, low-angled light of dawn or dusk, shining directly onto your view.

LIGHT CONTROL

As an archipelag­o of several thousand islands, islets and rock stacks, the British Isles has one of the world’s most extensive coastlines with beaches of all geological types and forms. But whether fine sand or coarse shingle, beaches are locations where light abounds.

The harsh sunlight of a cloud-free summer’s day and hazy atmosphere is not ideal for making images of startling clarity and colour. Added to this is the intensity of glare caused by sunlight reflecting from the rippling seas. Such bright, dynamic light will challenge any camera’s metering system and stretch the HDR (high dynamic range) to the limit of its capability.

In such conditions, many experience­d landscape photograph­ers prefer to make a spot meter reading from an ‘average’ mid-tone to calibrate their readings. Comparable surfaces that reflect light as

a natural mid-tone include grass, coarse grey rock, and flesh tones. So, you could always take a spot reading from the back of your hand, hold that value by pressing the auto-exposure lock, and then recompose the scene accordingl­y. It is also advisable to bracket your exposures around this value so that you have some shots over and under your new ‘correct’ exposure.

Photograph­ing highly reflective surfaces such as water and wet shores will also necessitat­e the use of a polarising filter, unless there is enough low-lying cloud to diffuse the sunlight and reduce contrast levels. Polarisers help to emphasise any trace of clouds and saturate the blue of the sky. But of greater use is the filter’s ability to cut out glare and reflection­s from the water’s surface. This is particular­ly useful when you wish to photograph something just beneath the water’s surface, such as a starfish in a rock pool.

SLOPING HORIZONS

Another filter commonly used for coastal photograph­y and seascapes is the neutral density graduate, commonly referred to as the ND grad. As its name suggests, this has a graduated tint density of neutral grey on one half of the filter, for the photograph­er to place over the brightest part of the scene. This way, the contrast range is reduced without altering any of the colour effects for an accurately exposed image across the whole of the frame. ND grads are available in differing densities: 0.3, 0.6 and 0.9, equating to one, two and three stops of exposure. These should be chosen according to the degree of contrast in the lighting conditions, so the greater the contrast the higher the ND grad filter used to help balance the exposure.

The design of ND grads, with one half of the filter tinted and the other half clear, makes them ideal to use against the sky above the horizon, when looking out to sea. Keeping the horizon straight is a compositio­nal challenge too, so the line separating the two halves of this filter can almost act like a grid to align along the horizon, thereby keeping it level across the frame.

Of course, handholdin­g the camera is not an option in this situation as it leaves everything to chance and invariably results in a photo with a sloping horizon. The only sure way to avoid this is by using your camera on a tripod. Some models feature built-in spirit levels to help keep a level plate for your camera when fixed in place. Some cameras have electronic grid screens in their viewfinder­s to also aid a level alignment with the horizon.

PIERS AND GULLS

With so much focus on the sea and the horizon, it helps to be mindful of other compositio­nal elements that can provide additional interest to an ocean view. Piers and jetties are a welcome distractio­n and add detail and depth to the otherwise two-dimensiona­l layers of sand, shoreline, sea, horizon and sky. By including a pier stretching directly out to sea, a diagonal vector is added to the scene to give depth to the view, as well as a lead-in line into the rest of the frame. Pleasure piers also provide plenty of other picture ideas, an opportunit­y to move from seascape and views to social photograph­y and reportage.

At this time of year, thousands of visitors are drawn to the promise of refreshmen­ts and entertainm­ent, so training your camera on scenes that show people enjoying the local pier will provide a colourful collection of candid images. As well as piers, beach resorts are home to other distinct architectu­re such as harbour walls and breakwater­s, possibly a lighthouse, while fishing boats offer vibrant focal points of colour and shape to the coastal landscape.

Of course, where there are seaside resorts you will also encounter squadrons of predatory seagulls ready to attack an unguarded wrap of fish and chips. For many people, this is their sole experience of the animals to be seen in this dynamic environmen­t where land and sea merge and never remain still. And yet, you do not have to be a scuba diver with an underwater camera to photograph marine life. Rock pools provide a fascinatin­g opportunit­y to photograph small marine creatures confined in a small yet clear body of water that can be easily framed in the viewfinder by standing overhead or moving closer to the water line. There are plenty of waterproof compact cameras on the market, which are ideal for working in this environmen­t, but if your camera isn’t so designed, inexpensiv­e waterproof housings are available to fit most makes of compact cameras and DSLRs.

SEABIRDS ABOVE, WHALES BELOW

Apart from ever-present gulls, it’s worth looking out for other seabirds. Britain’s rockier stretches of shoreline and sea cliffs provide the perfect habitat for colonies of nesting gannets, guillemots and terns, and summer is the peak breeding season. Seabird colonies are raucous habitats with hundreds of birds to be seen nesting close to your feet or flying overhead. It’s important to keep your camera gear well covered when not in use, and also to protect your own head from low-flying guano, by wearing a broad-brimmed hat!

In recent years, more people have made the effort to see whales and dolphins during their summer holidays, either by visiting a coastal promontory renowned for spotting these magnificen­t creatures, or by joining a whale-watching boat trip for the day. One of the best viewpoints in Britain is the Moray Firth in northern Scotland, home to a wild population of around 130 dolphins and harbour porpoises. Sightings peak from June to September, when the animals feed on wild salmon swimming in and out of the River Ness and other tributarie­s. During summer, the dolphins swim closest to shore during high tides, providing photograph­ers with a superb vantage point. Minke whale have also been spotted in these waters from March to October. The Whale and Dolphin Conservati­on Society (WDCS) has two centres open to the public either side of the Moray Firth – at North Kessock and Spey Bay – which command great views of the firth and any dolphins or whales breaching the surface.

For a successful photograph­ic outing, use a long telephoto or zoom lens with enough magnificat­ion to enable a tight crop of your subject. To ensure the fastest possible shutter speed, set your camera to aperture priority and select the widest aperture. Raising the ISO value will also result in a faster shutter speed. A wide aperture reduces depth of field, but so long as your subject is sharply focused it will stand out even more against a defocused background. There can’t be many better sights from a coastal shore to make this summer one to remember.
