There’s a current “Style & Technique” thread about front & back shifts with several competing opinions about which of these shifts (if not both) changes “perspective.”
Might this deserve a quick specialized thread?
BTW, I fall into the camp that says FRONT shift (L or R) will change perspective – not BACK shift. Same with rise/fall: that is, front rise/fall changes perspective – not back rise/fall.
But is it possible to summarize in a sentence what type of movement DOES change perspective (short of moving your entire tripod/camera)?
Perhaps I’d say … Whenever your lens axis moves in relation to your subject. (Would this be sufficient? Or perhaps I missed that lecture in LF 101?)
If this is correct, I can still think of lens movements that do NOT change perspective – namely, front axial tilt, and front axial swing…
What would your brief explanation be? Can you share moments from the field for illustration?
