I shoot architecture and sometimes have to fix distorted objects at the edge of a frame - usually because it was shot with a Canon 17mm TS.
I make a rectangle around the offending area, usually a piece of furniture or such that has become elongated, and then I use Scale to nudge the edge back into a more realistic rendering.
Somehow whenever I try to do this now the entire rectangle selection just shrinks in size as I nudge the offending edge inwards. I nudge one edge and top, bottom and the opposite edge of the selection moves inwards too. All four sides move in unison.
I'm stumped. Any ideas? Thanks.
