I've recently been in touch with my old hang gliding instructor who has a book being published soon and was looking for more shots for future use. This promoted me to finally get around to modifying my old zoom slide duplicator with bits of old tube and sticky tape so I could use it on an APS C sized sensor. I've put up some of the old shots I wanted to copy here. I look forward to reading Dunge Bottom - JC's a bit of a wit.
