Still life subjects are a terrific way to practice your photo skills in a controlled environment. With this rose, I used an aperture of f22 for maximum depth of field. This kept all of the petals sharp, even those to the outer edges. Then, using the rule of thirds, I placed the center spiral off to the left side to avoid a bulls-eyed composition. This was shot with a 100mm macro lens and I carefully arranged the scene so nothing but the rose was showing. Filling the frame with your subject can be an effective way to eliminate distracting backgrounds.
