The wind in the reeds

Here's another image in my recently begun quest to capture movement in nature using motion blur. Regular visitors may remember shots of the wind stirring some unripe barley and the waves on a shallow, stony-bottomed river. Today's photograph shows wind passing across a reed bed.

During a recent walk on a bright but quite windy day at Surfleet Seas End in Lincolnshire, I came upon this stand of reeds near the outfall of the River Glen. The low afternoon sun was offering some good contre jour shots of the feathery heads of the common reeds (Phragmites australis). However, the wind had other ideas. Each shot I made of selected heads using a long focal length lens was slightly blurred. So, rather than fight it I thought I may as well co-operate with the inevitable and do some deliberately blurred images. Looking at the wind passing over the reed bed I could see rippled lines being formed in the vegetation so I made these the focus of my efforts. It took about 6 shots to get this, the best of the bunch, with the lens stopped down to its maximum to produce the shutter speed of 1/10 second. I was pleased to get the blurred "waves" and at the same time some leaves and stems that were fairly sharp.

The wind that shakes the barley

click photo to enlarge
What are the most frequently photographed subjects. Well, if we're considering the average snapper, then it's probably babies and children, closely followed by holiday views. Amateur photographers have a fascination with sunsets, though people are also popular, as are landscapes. Birds and insects have gone from niche genres to mainstream, and some men (it's always men!) seem to photograph nothing but cars or motorcycles. All of these are perfectly reasonable subjects for the camera, and it's possible to take a perfectly good (or great) shot of each.

There is, however, a subject that attracts the casual snapper and the amateur in equal measure, and which is quite difficult to photograph well. I refer to running water! Many are seduced by the twinkle of light on a moving stream and try to capture it in a still image. They never do. Some place a neutral density filter over the lens and blur the water, making it look like fog flowing along. It creates an odd effect that some like. But the fact is, that what people see and like about flowing water just can't be captured on still photographs. To do the subject justice requires video.

A field of barley is another subject that also needs moving images to show the shimmering beauty of eddies of wind as they move across its silky green surface. However, that didn't stop me trying to get something of that flickering quality recorded on my camera sensor! In the absence of neutral density filters, on a dull day I selected a small aperture and low ISO, and photographed the barley as the strong wind whipped the seed heads back and forth. It took several shots to get something I liked. Does it capture that ethereal quality? Of course not. But it suggests it, and I'll make do with that!
