Well, many times the photos that we took of buildings tends to suffer from a perspective problem. They look like they are falling backwards. This is usually due previous reasons : use of? a wide lens that we used, the angle of the lens tilt or standing too near the building.
If you could counter these by standing far away from the building and using a telephoto lens, then you could avoid these perspective problems. Otherwise some post photo editing is required.
Before adjustments, this building looks like it is falling backwards. So we will use Photoshop to make some adjustments.
If you have Photoshop CS3/2, you could do this :
Use the Lens Distortion Correction filter by selecting FILTER > DISTORT > LENS CORRECTION.
In the Transform box move the Vertical Perspective and Horizontal Perspective sliders until your image looks great.? You may need to perform some cropping after the Lens correction has been done. Wahaa! Done
