Canon EOS-1DX with Canon 500mm at f/4.0 1/30th second ISO 500 - I took this photograph when I was at my local nature reserve on a cold December morning. I had my camera on a tripod with a gimbal style head. I was taking a photo of a resting Mallard at F4 at 1/30th second trying to get lots of feather detail, when I spotted this Grebe scooting across the water. Although my quick reactions meant that I managed to capture the subject, the shutter was nowhere near fast enough for a subject moving this fast. I would not normally have kept the image but I thought the effect the slow shutter speed produced made for an interesting and different image.
I really enjoy this image with the sense of movement and the effect the slow shutter has created.
