Edgar Payne

Edgar Payne's book "Composition of Outdoor Painting" is often recommended by landscape artists. It may be out of print, but there are often copies to be found online. There are some for sale at
www.amazon.com (A new copy is very expensive).

In the book, Payne categorises various types of composition to help the reader design their paintings rather than simply capturing random snapshots of the landscape. 

These compositional types are not intended to be fixed recipes. The artist should adapt them to use in original ways.

Compositional design does not imply that one is 'fudging' reality, it is simply a means of knowing what to look for when deciding what to paint.
