Closer isn't always better, but it's usually worth checking out. It forces you to look not only at the subject, but also its shape and how it works within the camera frame. In other words, it encourages you to think as a visual designer, not just as a gardener or horticulturist. By moving in close, we get to experience the intimate details of this lotus (Nelumbo 'Mrs. Perry D. Slocum'). And graphically, the image benefits as much from the negative space (the green, leafy areas surrounding the petals) as it does from the flower filling the frame and "bleeding" off all four sides.
