This encyclopaedia-style guide to drawing techniques absolutely stands on the quality of its illustrations. These are sensitive and Davids working methods adapt themselves nicely to the medium and technique in question at the time.
Just about every drawing medium is here, from graphite pencils and sticks to ballpoint, felt-tips, watercolour pencils and soft pastels. Subjects include flowers, landscapes, still lifes, animals, buildings and people. Techniques cover toning, layering, hatching and blending as well as simple mark-making. Obviously, not every combination of subject, medium and technique can be included, but the matching is logical and the results always enlightening.
As well as functioning as a source of reference, this is also a book to dive into and explore for ideas and inspiration. Its a lot of fun.
