a man seated on the sand of a serene beach, holding a rectangular wooden frame. Only parts visible are his face outside and above the frame and hands outside the frame, gripping its edges.

The alignment and continuity of elements such as sand, and sky within and outside the frame should be precise. The key is to maintain a clear boundary of the frame while ensuring the transition of the beach scenery through the frame is indistinguishable from the surrounding environment
