Simulating shift axis to correct building deformation

When we use the wide-angle lens Ching to shoot the building, or from the top down to shoot the building, there will be a phenomenon called "perspective convergence" to make the lines on the building appear oblique, and finally converge to a point, rather than the building should have horizontal vertical lines. The phenomenon of perspective convergence is shown in the following illustration:

When this happens, the building looks like it's deformed, and it makes the audience feel more awkward. Correct this phenomenon can use special axis lens, but the operation is more troublesome and the cost is relatively high.

We can correct this perspective convergence through Photoshop's "Lens correction" feature.

Open the picture in Photoshop, then click Filter-Lens correction in the menu bar, and then eject the image below. At this point we adjust the "vertical perspective", the value into a negative to see this phenomenon is corrected, the building itself vertical lines will not be brought together.

After correction, the whole picture will have a crush feeling, this is we can press CTRL + a full selection of pictures, and then press Ctrl+t to transform the picture, as shown in the following image of the edge of the picture to pull up a little, so you can return to normal effect.

The final effect of the image shown below, is not the appearance of the building is more comfortable!
