This was never a good photograph. It was under-exposed and badly composed, yet there were engaging components such as capturing a record of the typical behaviour of visitors to Avebury. I was in conversation with another visitor on a different occasion who was unimpressed by the antiquity. She memorably summarised it thus: "I walked a bit, and saw a pile of stones. I walked a bit more and saw another pile of stones".
Maybe Avebury's antiquity is best left to archaeologists. It's a fine place for a bit of exercise though.
I have attempted to rescue the better aspects of the picture by using the Lightroom software but there are limits with the jpeg quality.
Nikon D90 and AF Zoom-Nikkor 70-300mm f/4-5.6G lens at 190mm (about the limit of its best performance). I've bought and sold two of these cheap and flimsy lenses which have their strengths and are light in weight.
Avebury Stone Circle in Wiltshire attracts many visitors. I think these girls were in a party from the United States.
