There is a book of his writings on photography. It is a collection of articles and letters. It may actually be called "On Photography". I have a copy somewhere in my house. He describes his equipment and technique more than his daybooks.
The title is Edward Weston on Photography, edited by Peter C. Bunnell and published in 1983 by Gibbs M. Smith, Inc., Peregrine Smith Books. Another interesting book of writings about Weston by others is Edward Weston Omnibus, edited by Beaumont Newhall and Amy Conger and published in 1984 by the above publisher.
