 Cloud Shadow Projection over Novi Ligure, Italy

   November 09, 2022

    Nuvola e ombra (2)

   Photographer:  Valter Luna

   Summary Authors:  Valter Luna;  Jim Foster

   The photo above showing an eye-catching  cloud shadow was captured
   from my home in Novi Ligure, Italy on July 30, 2022. Shadow projections
   such as shown here are formed when a shadow is cast upon a layer of
   thin dust or  haze. The  scattering angle of sunlight by the
    aerosols within the layer plays a role in observing the projected
   shadows. Typically, you’ll have more success seeing them if you’re
   looking in the vicinity of the Sun – about 10 degrees away or about the
   width of your fist when extended as arm’s length. Also, it seems that
   they can be seen more often in  cumulus congestus clouds than in
   other cloud types.

   Photo details: Nikon D100 camera; Sigma 18-250 lens; 50mm; 1/200 second
   exposure; f / 16; ISO 200.
