Perspective

The perspective is used to create the illusion of three dimensions to an image. We are recording with the camera a scene that has 3 dimensions. But when viewed on your computer or print it on paper, happens to have 2-D (dimensional) and so the image looks flat and less shocking.

The pictures that have depth are generally more interesting and striking than the flat photos. There are several resources you can use to give a three dimensional feeling to the image.

Linear perspective is when at least 2 parallel lines preface to infinity and end up together at one point. In the real scene is obviously not together, but we will have the feeling that if they get together. Somehow we are deceiving our brain that will tell us that there is distance and depth in the image.

If we change the focal length of lens, the sense of depth will also vary. The wide-angle lenses give the impression that the planes are farther apart, so will help give a sense of depth. By contrast, the telephoto lens, flatten the image.

Also making the angle will influence perspective. Imagine you're photographing a row of trees. If we take a photo in front of all the trees will be the same size. But if we on the side of the first tree, at some angle to photograph all the trees, the first going to look bigger and the rest will go as it is shrinking away from the camera.
