A selection of Adder images. For the avoidance of doubt, these images are taken with a telephoto lens & teleconverter (usually with a focal length of 560mm), and do not disturb the animals. See http://brettlewisphotography.blogspot.co.uk/2014/03/wildlife-photography-costly-impact.html?m=1 for a reminder of the ethics of adder photography (and the appalling behaviour of some photographers in pursuit of the 'perfect' picture). This is a sensitive, declining species- and wildlife always comes first.
