Shadow lighting effects
Use light to highlight one feature to bring out another.
A good example of using light in this way is to illuminate a statue or structure which also creates a shadow onto a wall or fence. Using a spot light pointing upwards can highlight a row of flowers or plants, whilst also lighting a tree behind. You can position the lights at many angles to achieve this result, and it is best done during the day first as you can clearly see the important parts of your garden. Spike lights are especially good at creating this effect.
