Big horn mommy, this lady is middle age, the horns are about as long as females attain. Most of my large mammal images are portraits, if I came get close enough without changing their behavior. Most of these images are captured with 600mm f/4 or 400mm f/2.8, full frame or half frame cameras depending on distance to subject. I try to avoid enlarging as this lowers image quality. You are viewing the good ones, most are failures due to many factors, including pilot error. I should talk about cameras and mega pixels. This image was shot with a lower resolution camera (D2H) compared to todays 24 megapixel bodies. Even at the low pBase resolution you can see eyelashes.
