A primarily Romantic painter, Aivazovsky used some Realistic elements. Leek argued that Aivazovsky remained faithful to Romanticism throughout his life, "even though he oriented his work toward the Realist genre." His early works are influenced by his Academy of Arts teachers Maxim Vorobiev and Sylvester Shchedrin. Classic painters like Salvator Rosa, Jacob Isaacksz van Ruisdael and Claude Lorrain contributed to Aivazovsky's individual process and style. Karl Bryullov, best known for his "The Last Day of Pompeii", "played an important part in stimulating Aivazovsky's own creative development," according to Bolton. Aivazovsky's best paintings in the 1840s–1850s used a variety of colors and were both epic and romantic in theme. Newmarch suggested that by the mid-19th century the romantic features in Aivazovsky's work became "increasingly pronounced." She, like most scholars, considered his "Ninth Wave" his best piece of art and argued that it "seems to mark the transition between fantastic color of his earlier works, and the more truthful vision of the later years." By the 1870s, his paintings were dominated by delicate colors; and in the last two decades of his life, Aivazovsky created a series of silver-toned seascapes.
