Brassaï captured the essence of the city in his photographs, published as his first collection in the 1933 book entitled Paris de nuit (Paris by Night). His book gained great success, resulting in being called "the eye of Paris" in an essay by his friend Henry Miller. In addition to photos of the seedier side of Paris, Brassai portrayed scenes from the life of the city's high society, its intellectuals, its ballet, and the grand operas. He had been befriended by a French family who gave him access to the upper classes. Brassai photographed many of his Artist friends, including Salvador Dalí, Pablo Picasso, Henri Matisse, Alberto Giacometti, and several of the prominent Writers of his time, such as Jean Genet and Henri Michaux.
