I use the perspective crop tool often and very successfully to correct converging vertical etc.
Today, for the first time, when I use the tool I got a vertically squashed result....see the attached screen shots.
I have tried restarting my PC (which runs Windows 10 and PS CC), tried using the tool on another image etc, all to no effect..I always get a vertically squashed result.
Please, can anybody tell me what's going on and how to overcome this.
regards
Brian Ormerod
