The beautifully preserved Medieval cloisters at Lacock Abbey are built from Cotswold limestone. At 3.20 in the afternoon, the sun shines directly into the corner of the quadrangle, illuminating two sides almost equally. In April, the sun is just high enough in the sky at this time that the windows project a pleasing pattern of light and shadow across the floor. As the sun emerged from cloud, I made this image using a panoramic tripod head to take six overlapping frames in portrait format, each at three different exposures, between them covering a 90 degree field of view. I stitched the resulting images together using PTGui to create a high dynamic range file, then post-processed with Photomatix to bring out the superb detail and rich tones of the stonework.
