Once she reached the shallow tip of the lake she splashed and rolled around getting her head and ears wet.  I guessed that she would begin to shake her head and so I quickly selected a shutter speed that I hoped would capture the motion of her head shaking and radiating water droplets while keeping her eye in focus. I have been trying for years to get photos of wildlife doing this behaviour but each time I have been a bit off with the shutter speed and aperture with the image either too blurry or too static. This time I got lucky! She turned and faced me before shaking her head back and forth to get the water off her face and ears.  For sure, one of my favourite photos to date.
