Stop Buildings from Leaning Back?

To get rid of this keystoning effect, go to the Lens Corrections panel (in the Develop module’s right side Panels area), click on the Manual tab, and then drag the Vertical slider to the left until the building looks straight (it stops looking like it’s leaning back). There’s an automated method, too: click on the Profile tab, and turn on the Enable Profile Corrections checkbox (your lens make and model should appear in the pop-up menus below. If it doesn’t, just choose it yourself). Next, click on the Basic tab and, in the Upright section, first click on the Auto button and see how that looks. Chances are it fixed the leaning back problem. If it didn’t, then click on the Vertical button. If neither of these did the trick, click on the Off button, and then go back to the Manual tab and do it manually (like I mentioned at the start of this tip).
