I spent 3 days in Rocky Mountain National Park. Weather was pleasant and shooting conditions were perfect. There were 2 main meadow areas that were predictably good. I shot for a few hours in the morning and late afternoon. The first 2 and last 2 hours of light are the best for pictures. The light intensity is much softer and the color is best then.
This guy was one of the better performers for the camera, although there were plenty of participants, some larger.
This was fairly early. With the brighter light later I would have been able to have a bigger F stop number for even greater depth of focus. This was shot at F8 which isn't bad since the animal's plane is parallel to my camera.
Things to notice in this photo are the activity inferred by the position of the legs and the bugling; clean background; soft light; contrasting background.
