How to use a Canon Wide Angle Lens
from: ConsumerEvidence.comThere is an interesting feature when using a canon wide angle lens and that is the perspective stretching capability. This simply put means that when looking through a wide angle lens, it may seem that the distance between the objects more than it really is. When looking at an object that was not very far away, it may appear much farther off. The object's proportion may increase dramatically; it can make the one closest to the camera appear to be huge, and those farthest away seem to fade into the distance.
If you can imagine looking through a wide angle lens at two parallel lines stretching out away from the camera, the lines will merge at a distant point. This, for the wide angle lens, is called the perceptive vanish point. This means that at this distance they may represent a small point or cannot be seen at all. The normal lens camera can be farther away from the focal plane than for a wide angle lens.
As an example if you have two children who are similar in height, one may be nearer to the camera and the other may be a few feet farther away. Now you can take a photo with a wide angle lens, you will now see that the one who was farthest away looks a lot smaller when in fact they were of similar height. This will give you some perspective and effect you can achieve by using a wide angle lens understanding the stretching perspective.
There are a lot of benefits for a photographer when using a wide angle lens, as mentioned when there are two subjects, the one nearest the camera then becomes the primary subject. It is easy to assume this without additional thinking, and this happens when using a wide angle lens as it is much simpler to focus the viewer’s attention to the main subject.
