Nasmyth was also a highly influential teacher at the Trustee's Academy in Edinburgh. Among his students were painters who took the landscape tradition into the nineteenth century. They included Andrew Wilson (1780-1840), who would become Master of the Academy in 1818, the watercolourist Hugh William Williams (1773-1829), clergyman and artist John Thompson of Duddingston (1778-1840) and probably the artist that would be most directly influenced by Nasmyth, John Knox (1778-1845). Williams' most famous work are interpretive versions of Greek landscapes, based on sketches taken on his travels there, among them The Temple of Poseidon, Cape Sunium (1828). His close friend John Thompson focused on a dark dramatic version of Scottish landscape, as in his most famous work Fast Castle from Below (1824). Knox directly linked Nasmyth's style with the Romantic literature of Walter Scott. Knox's Landscape with Tourists at Lock Katrine (c. 1820), was a commentary on the tourist trade that grew up in the Trossachs in the aftermath of the publication of Scott's poem The Lady of the Lake in 1810. He was also among the first artists to take a major interest in depicting the urban landscape of Glasgow. Towards the end of his career he undertook panoramic works of the views from the top of Ben Lomond, which played a part in opening up the Highlands as a spectacle that would be taken up by artists in the second half of the century.
