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.
