Robert J Kasieta submitted this image taken with a Nikon D3, with an exposure of 1/3200 sec at f/8, ISO 2500. Robert did a great job keeping the details in the bears despite being against the white snow I am curious as to why Robert used such a fast shutter speed since the bears were standing still. A lower ISO could have been used and still maintained a fast enough shutter speed to freeze movement if needed. The photo appears to be a little underexposed. The details in the mother's face are very sharp but the cub's face is a little soft. Using a 500mm lens Robert was able to fill the frame with the animals which makes for a tight image and gives a sense of scale between the larger bear and the smaller one.
