This stunning drake Goldeneye took the opportunity to charm two ladies at the same time! A full display of water jetting and neck bending, somersaulting and generally clowning around was offered to me on a plate some 50 yards from the hide. I used the 600mm lens with 1.4x TC giving a maximum of 850mm focal length. Exposure -0.3. WB set to Automatic as the light was changing constantly. Aperture F/6.7.
