VANISHING POINT CLONING
Use this filter to clone along the perspective of an object.
The ‘Vanishing Point Filter’ found under the Filter menu [1] lets you clone in perspective. Here you can use it to clone over the awnings [2] and tidy the face of the building, using the nearer building details as a source [3]. This wouldn’t be possible with the conventional Clone tool due to the perspective of the building, but with the Vanishing Point Filter, it’s quite a simple job. Click on four corners to plot out a plane over the rectangular face of the building using the Create Plane tool [4], then grab the Clone tool [5]. Use the settings at the top of the dialog [6] to resize the brush tip, then Alt-click to define a nearby source before cloning over the awnings to remove them.
