CHANGE YOUR PERSPECTIVE

As you know, the world around us is in three dimensions, that is, it exhibits depth. Photographs either printed (or paintings for that matter) or viewed on the screen are rendered “flat” in two dimensions without any depth. One of the techniques used by photographers (and painters) to show apparent depth in a twodimensional flat rendering is through “perspective” which is technically a projection. Due to perspective, objects close to the viewer look larger than those that are far away. This property is used to create the impression of depth in a photograph and is used extensively, for example, by landscape photographers. More of this shortly.

Perspective also manifests itself in other ways. One of the frequently encountered problems when photographing tall buildings or structures occurs because we tend to point the camera upwards, with a wide-angle lens to get the whole building in the frame. This causes the building to appear as if it is leaning backward (Picture 1) and is erroneously called distortion. However, it is not, and hence is not a defect! This is due to perspective. There are a few ways to solve this problem. Examples are choosing a proper shooting position, shifting the lens axis by using a suitable camera or lens, employing suitable post-processing techniques, etc. In both Lightroom and Photoshop, there are multiple tools available to achieve the needed correction, but the Perspective Warp function in the latter is unquestionably the most powerful. This article will explain to you how to use it.

Perspective Warp is in the Edit section of the main menu of Photoshop. You can invoke it by
