    I presume you mention this in the context of the second photo having
    gaps next to the lighthouse and the adjacent building. I could imagine
    that this is only a "colour feature" from how the "missing" parts are
    illuminated by the sun. The way how they are iluminated may have
    turned them to the same blue colour as the sky. I observed this some
    time ago in the context of "ships in the sky" where part of the sea
    received the same colour as the sky. You find these photos here
