The '''diagonal method''' ('''DM''') is a [[rule of thumb]] in [[photography]], [[painting]] and [[drawing]]. Dutch photographer and lecturer Edwin Westhoff discovered the method when, after having long taught the [[rule of thirds]] in photography courses, he conducted visual experiments to investigate why this rule of thirds only loosely prescribes that points of interest should be placed more or less near the intersection of lines, rather than being rigid and demanding placement to be precisely on these intersections. Having studied many photographs, paintings and etchings, he discovered that details of interest were often placed precisely on the [[diagonals]] of a [[square (geometry)|square]], instead of any "strong points" that the rule of thirds or the photographic adaptation of the [[golden ratio]] suggests. A photograph is usually a rectangular shape with a ratio of 4:3 or 3:2, infrom which casethe onediagonals shouldof lookthe photograph are placed at the [[bisection]] of each corner. Manually placing certain elements of interest on these lines results in a more pleasing photograph.<ref>Hartel, M. (2008). Urban expression. Digital Photographer, 74 (September), 30–42.</ref>
