The allure of dark skies

click photo to enlarge
After the coldest spring for a few decades the summer of 2013 eventually turned out to be one of the warmest and sunniest of recent years. There were blue skies and white clouds a-plenty, enough to satisfy the requirements of the lover of warmth and the photographer of sunny, congenial scenes. Even the farmers were happy because precipitation arrived reasonably regularly in ample but not excessive quantities. Early October proved to be significantly milder than usual too, with temperatures daily above 20° Celsius. However, much as I enjoy mild weather and the feel of the sun on my back, the photographer in me does eventually yearn for more dramatic weather, the sort that the British Isles is known for, with fronts moving across the land bringing cloud, rain, sun, breezes and the rest: what the forecasters describe as "changeable" weather. Well, as the previous post rather suggests, with a dip in temperatures, a rise in wind speeds and increased cloud cover, change is now upon us.

Today's photograph was taken as that change arrived. It shows the decorative roof of a building on the corner of New Road and Hall Place in Spalding, Lincolnshire. Across its ashlar face, between the ground and first floors, stone lettering proclaims that it was built for S & G Kingston, Land Agents and Surveyors. It was erected in 1907, the work of J.B.Corby & Sons, and is in a free style, a sort of modified Jacobean. The windows have mullions and transoms, decorative oriels sit over the main entrance and at each end of the curved facade, and above are turrets, a strapwork balustrade, tall chimneys and a weather vane. It was this cluster of verticals that caught my eye when I saw them sunlit against deeply dark clouds that threatened rain. The contrast of the glowing stonework against the black sky appealed to me and so I took my photograph.

The drama of a sunlit subject against an uncharacteristic dark sky has always appealed to me. Unfortunately photographs with these qualities aren't easily acquired because a suitable subject doesn't always present itself  in the right place and sometimes a camera isn't to hand. I did, however, catch an old walnut tree in these circumstances last year.

Looking up

Mankind's impact on the earth is much discussed these days, particularly with regard to global warming, diminishing resources, the extinction of life forms, and the despoiling of land and the sea. Such are the demands that we make of our finite planet, it is increasingly hard to find a place where the mark of man is not visible. The uninhabited desert is frequently littered with the debris of wars. Mount Everest is marked by the dumps of successive generations of climbers. The jungles of the tropics are scarred by new roads and burnt clearings. And now we read that the seas are becoming a soup of decaying plastic as well as a dump for sewage and other noxious materials.

So, where can we look to see a sight unchanged from that seen by our ancestors? Well there clearly are still some locations on land and sea but they usually have to be sought out. The most convenient place is actually above our heads! Especially at night. The stars have held a fascination for mankind ever since he first glanced skywards. They offer a unique sight that is available to all without the inconvenience of travel. Or they should. The problem is that light pollution from cities hides all but the brightest stars, the moon and planets, and today it's only in the countryside away from street lighting that we can see the heavens in all their beauty - the odd satellite or aircraft permitting! The International Dark-Sky Association and its affiliated organisations work to return our birthright to us. Interestingly the shape of the constellations has changed slightly since Stone Age man gazed upwards, but essentially, what he saw, we see.

When the builders of our medieval cathedrals came to decide how to finish their ceilings they often painted golden stars on a blue background to represent the night sky or heaven, the destination of believers. As vaulting became more intricate and the short decorative ribs called liernes were introduced, it seemed obvious to make it into a star pattern (called a stellar vault), and symbolise heaven with one beautiful, radiant star. That is what happened to the underside of the crossing tower of Peterborough Cathedral shown in the photograph above.
