A great photographer doesn't just take lots of shots hoping to get one or two good ones, but first understands and envisions what will make this shot a beautiful image and then creates that beautiful image with a multitude of skills and tools.
A great photographer not only creates great images in the field with their camera and artistic competencies, but also then further uses their understanding and mastery of Photo Editing Software to further refine and sometimes "recreate" an image into a unique photographic artwork.
