Starr stood on the edge of the field and called to her horses. She looked left, then right, then called them again. On the third call, you could see them running toward her from a great distance. With my trusty Nikon in hand, I prepared to capture the moment. As I watched the horses, partially concealed in the tall grass, gently kicking dust up into the air, I regretted not bringing my 300mm with me and regretted more that I didn’t have an even longer lens.
