Rembrandt lighting is a dramatic light. This pictorial technique uses sharp contrasts between light and dark. These are usually bold contrasts that influence the whole composition. As such, this is a type of lighting that best suits low-key photography. It also adds a mysterious atmosphere to the image. 1920 - World War I is over. The enthusiasm for the end of the war is uncontainable. There is the rapid growth of the mass media, that is the affirmation of cinema, radio, cabaret, art and science. Positivist thinking has won, humanity seems to be heading towards a destiny of happiness and full fulfillment, where there is no place for poverty, disease and war. Taste is less and less oriented by academic dictates, expression of an aristocratic elite, and increasingly oriented to satisfy the needs of a bourgeois, entrepreneurial and dynamic class, which in any case wants to combine profit with beauty. It is the period of the "Belle Époque" and of the Art Decò.
