I love it when people talk about photography, digital or analog makes no difference when they talk, the results are important.... or you're able to "see" or not, some learn to "see", most never learn to "see".
""Are those done with a Rollei or Mamiya or just cropped?""
if your into photography you should have seen that these square portraits are done with a Hasselblad, and are not cropped, the frame tells us.
In fact I never cropped a single picture, nor digital nor a film negative while exposing it on paper.
