The best way to reveal texture is when light crosses an object. The image can become contrasty in this cross light. Early morning light on a clear sky day will give you a strong, crisp light with hard-edged shadows. It does not matter if your subject is 100 feet tall, or an inch square, the naked sun will rake its light across your object. I enjoy close ups as we see details we probably did not notice before. The silver gray leather and shoe laces get their day in the sun.
