What I didn’t expect was how much the shape of the frame would mess with the rest of my photography vision. My pictures are now more frontal, more centered, more symmetric than anything I shoot on 35mm (or with any other rectangular ratio). The short version of the idea: the form of a medium reshapes how we perceive things, more than the content it carries. Square format is awesome! Better yet, dig through your camera’s menu for the setting that records square, so the viewfinder shows you a square while you shoot.
