I am an architect, and proportion is a very important issue in facades. When I use the wonderful Perspective Correction module combined with the Lens Correction module, I get truly orthogonal results. The problem is that these are out of proportion. A square window becomes a rectangle.
Is this possible to achieve using the implemented features? Or would that need extra dev work?
(other softwares which can achieve the square proportion are PTLens, or Hugin, but they require lots of user fiddling and fall out of Darktalbe workflow)
