Having thought about it, I imagine that making a pinhole "triptych" incorporating escalators and people might be quite abstractive/interpretive.
It would also no doubt be a moving experience...
“The photographer must determine how he wants the finished print to look before he exposes the negative.
Before releasing the shutter, he must seek 'the flame of recognition,' a sense that the picture would reveal
the greater mystery of things...more clearly than the eyes see." ~Edward Weston, 1922.
