Hi,
Here is a link to ShiftN :http://download.cnet.com/ShiftN/3000-12 ... 75063.html
With this app, you can have buildings with straight lines, no more distorsion caused by lenses.
ShiftN does one thing only, but does it very well. The process is entirely automated, and fast, but it is possible to manually change the result, if not entirely satisfied. But most of the time, the result is perfect.
This free app is hidden in the web, most often not mentionned anywhere, even when you type in : free apps, in Google.
For Windows only, but is working with Wine.
