Fotoreproductie van een prent van Grotta Azzurra te Capri before 1879

This photogravure, created before 1879 by renowned photographer Giorgio Sommer, depicts the Grotta Azzurra, or Blue Grotto, on the island of Capri. Sommer, known for his scenic photographs of Italy, captured the dramatic entrance to the sea cave, showcasing the play of light and shadow. The image highlights the cave's distinctive azure glow, a phenomenon caused by the refraction of sunlight through the water. This photogravure is an excellent example of Sommer's mastery of the photographic process and his ability to capture the beauty of natural wonders.
