Duval studied painting with Alexandre Diday, a landscape painter. In his paintings one finds his love for the calm of the landscape and the distant horizons.
As an Orientalist he made his first trip to Egypt in 1869, where he followed the course of the Nile. He made a second trip in 1874 with his painter friend Louis Auguste Veillon. He made a last trip to Egypt in 1883.
