He was articled to a painter named Tillet in London, and studied mezzotint engraving under Isaac Beckett and Jan van der Vaart.
Smith became the favourite engraver of Sir Godfrey Kneller, whose paintings he extensively reproduced, and in whose house he is said to have lived for some time.
The rest of Smith's plates have sacred, mythological, and genre subjects after Titian, Correggio, Parmigianino, Carlo Maratti, Godfried Schalcken, Egbert van Heemskerck, Marcellus Laroon and others.
Smith also reissued many plates by Beckett, Bernard Lens, Williams, and others, retouching them and erasing the original engravers' names.
Smith's latest print appears to have been the portrait of the young Prince William, Duke of Cumberland, after Joseph Highmore, dated 1729.
