      The turquoise waves crash against the dark, jagged rocks of the shore,
      sending white foam spraying into the air. The scene is dominated by the
      stark contrast between the bright blue water and the dark, almost black
      rocks. The water is a clear, turquoise color, and the waves are capped
      with white foam. The rocks are dark and jagged, and they are covered in
      patches of green moss. The shore is lined with lush green vegetation,
      including trees and bushes. In the background, there are rolling hills
      covered in dense forest. The sky is cloudy, and the light is dim.

      The camera pans across a cityscape of tall buildings with a circular
      building in the center. The camera moves from left to right, showing the
      tops of the buildings and the circular building in the center. The
      buildings are various shades of gray and white, and the circular building
      has a green roof. The camera angle is high, looking down at the city. The
      lighting is bright, with the sun shining from the upper left, casting
      shadows from the buildings. The scene is computer-generated imagery.

      Drone view of waves crashing against the rugged cliffs along Big Sur’s
      garay point beach. The crashing blue waters create white-tipped waves,
      while the golden light of the setting sun illuminates the rocky shore. A
      small island with a lighthouse sits in the distance, and green shrubbery
      covers the cliff’s edge. The steep drop from the road down to the beach is
      a dramatic feat, with the cliff’s edges jutting out over the sea. This is
      a view that captures the raw beauty of the coast and the rugged landscape
      of the Pacific Coast Highway.
