Diagonal Method
A compositional approach placing points of interest on the 45-degree bisectors drawn from each corner of the frame.
In depth
Proposed as an alternative to the rule of thirds, the method claims that photographers instinctively place important detail along these bisectors. Its practical value is as a second opinion: an image that feels slightly off under thirds sometimes resolves when checked against the diagonals instead.
Examples in practice
An eye placed on the diagonal from the top-left corner sits marginally differently from the thirds intersection nearby.
