Framing or Focal Point?
Sometimes objects in the landscape can be both a framing device and the focal point of a view, depending on whether your focus is near or far. Here's a tree which frames a view most of the time, while having its own sculptural interest at all times. However, when the tree trunk is lit up by the late afternoon sun, it becomes the focal point from any point of view throughout the garden. Changing light can do that in a garden, and is not always easy to plan for. Trees grow, views get obscured, light no longer reacts within the garden in the same ways over time. This particular garden is well located at the crest of a west facing slope overlooking the San Francisco Bay, so it presents many opportunities to use late afternoon light in interesting ways.
