Now, having all the different negative formats in mind, I'd like to propose that (1) for the sake of simplicity (and not having enough spare space in hand) let us divide 6x6 negative roughly into 4 quadrants, but (2) cylindrical panoramic one into 'dodeciles'. What I mean -- there has to be a part of the picture, that human eye can hold in one glimpse and here the quadrat is definitely different from any rectangular format, not to speak about panos. The direction of eye movements when watching a picture is simultaneously defined by the natural (reflexive) forge and by the guiding elemetns of the picture. If these do not match, the eye will wander 'aimlessly' while the watcher feels uncomfortably. Just think about Vasarely and all the other op-artists. Peeter PS: Already in fairy-tales the rule of 'thirds' was an important compositional technique -- 3 sons and all this repetitive action, performed 3 times before succeeded etc. P
