Painting lighthouses has been a frequent subject for artists for several hundred years. It requires a special skill set that includes both drawing & painting skills. But because of the function lighthouses serve they are usually found in distinctive, often remote or rugged landscapes along coastlines. Their often stark white shapes stand out against the sky right on the edges of the sea where the shoreline, beaches, setting and sky all contribute to their uniqueness.
With Lighthouses... it's always about the light, time of day, and weather.
