Composing without the Golden Section
I liked this picture for its simple colour contrast.
I think it works well in a square format and it is not deliberately composed using the golden section.
There is a little subtle detail in the green shape behind the fence which shows through as two green stripes. These do sit very close to a vertical third but the yellow bin dominates the composition. This contrasts with the black fence and the shadows cast by the railings in this photograph.
