The one point perspective is one of the easiest perspective viewpoints to use in your photo composition. All you need to do is to look out for converging lines in a scene and take your picture. Simple, no?

It is very easy to find converging lines, just go to any road and stand in the middle and look down the street (not in a busy intersection, please, you know what I mean). The lines from the road including buildings (if you are in the city) will create a straight line meeting to a point in the distance. This kind of picture taken creates a sense of depth, even a sense of movement of one going forward on the long road to somewhere. You can find this kind of perspective just about anywhere. In a tunnel, in a hallway, or anything that creates converging lines.
You can place the point right smack in the middle, which is what most photographers would do to create symmetry and of course tunnel like vision. However to make a more interesting one point perspective is to put the point at third, either at the upper side or if at the side to create an additional diminishing perspective element to the photo.
Lines that can be easily seen and converges into a vanishing point is also known as linear perspective. Strong lines create useful compositional device as a lead-in line to direct a viewer from the front of the image to the distant background. Other possible lead-in lines include trees, fences, even footprints! Just keep your eyes open!
