I don't know, André. Balance may be more obvious with a rectangular format, but it's not clear that it's easier, as such. The square seems to give both vertical and horizontal balance equal attention.Originally Posted by Juba
To me, the square 6x6 format is perhaps more neutral. One can compose to the square, or see an alternative composition within the square. In print, the square may also be more neutral, avoiding both the imposing feel of portrait orientation and the relaxing quality of landscape orientation.
Ultimately, one might posit that if the final image depends on the format to achieve its visual objective, more time might have been spent on subject and composition selection.
