SWALLOW DRINKING (Hirundo rustica)
drinking from garden pond in Sussex. So as not to upset the bird’s normal drinking behaviour pattern, the picture took two weeks to prepare .
The photograph was taken in 1977 with a Hasselblad camera on 50 ISO film, using high speed flash at 1/10,000 sec. Now in 2012 a similar picture (although not as sharp) could be taken using a digital camera set at an ISO of 10,000 or more.
