As far as the exposure it concerned, I used the automatic exposure on the digital camera, there is no exposure control. It was a bright day and the sky was hazy. I built the pile of stones in about half an hour then I took the snap. I started quite a craze of stone artistry that day, it was even on TV. The composition was done at Rottingdean, near Brighton, on the south coast 50 miles from home in south London. I go there on day trips quite often in the summer. We had snow today. It started in the early hours of the morning and went on until 2 pm. Unusual in April for London - Global Warming - Bah Rubbish! Chris
