1) Study Reflections. Investigate the way in which the reflection changes its shape as you change your position, both from side to side and up and down.
2) Select Your Settings.** Use the widest-angle setting on your camera, and supplement this with a wide-angle attachment, if possible. You might need to use flash to fill in any shaded areas.
3) Move in Close. Often, the best view of a reflection can be found right down at water level, because it is along the water line that you can get an almost fully symmetrical view. Try turning your camera to bring the lens closer to the water, taking care not to get it wet. Treat the subject like a landscape, using maximum depth of field.
