An illusion built into the design of this pool makes it seem the pool is actually part of a larger lake (situated below this pool).
An illusion built into the design of this pool makes it seem the pool is actually part of a larger lake (situated below this pool). The (man-made) pool itself is located on top of a grotto and has an integrated waterfall spilling into the lake. The transition point is at the fountain and is nearly invisible in the photograph (no extra processing). Captured at Mayfield Garden in NSW.
