Like waiting for clouds in “Aviator”

Just spent three days on a photo shoot in Rockland, Maine, waiting for a few clouds to appear to give depth to the endlessly bleak and white sky. Not a shred of blue anywhere. Only a white horizon on white background, the kind of light that hurts the eyes after a while and gives you a headache.  The situation reminded me of the scene in the movie “Aviator” when the filmmakers working for Howard Hughes, played by actor Leonardo DiCaprio, realize they need clouds to show the speed of the warplanes dogfighting in the sky.
