Of all the possible aspect-ratios (eg 3:2, 4:3, 5:4) typically encountered in a camera frame, square (typically 6x6 film) stands out as particularly noteworthy: it makes optimum use of the lens' image-circle; it does not require rotation to get portrait or landscape formats; composition for square is distinct, having corners and centre to consider rather than "thirds" or similar.

Most of the photographs below have been made using either a Bronica SQa, a Hasselblad 500C/M or Shen-Hao large-format view camera subsequently cropped to square; a few digital images have been composed by building-up using panorama stitching techniques to the same effect.
