3 Tips for Using Linear Perspective in Photography
Linear perspective in photography is a way to give the impression that there is depth in the picture. It creates a 3-D impression and makes the scene more realistic. There are ways to capture this perspective in all of your photographs.
1. Short Lens
The use of a short, focal length lens can help to alter the perspective in your photos. When the focal length of your lens changes, but the distance of the subject remains unchanged, the size of the objects in your images will change without any change in the perspective. When the photographer uses the right mix, he can create a photo that will look either shallow or deep. This is only an illusion, however, it is important to the compositional factor of the photo.
2. Horizon Line
The horizon line should correspond with the viewer’s eyelevel. When the viewer shifts their viewpoint, the horizon line should shift too. As a rule of thumb, all of the objects that are above the horizon should tilt upward and if they object is below the horizon line, it should tilt downward. The distance that each object tilts will determine the degree of which it should tilt from the horizon.
3. Vanishing Point
The point in the horizon where the lines converge is commonly called the vanishing point. For example, a photo of train tracks, where the linear perspective was wonderfully captured, will show a vanishing point where the rails of the track converge at the horizon. The best way to create a vanishing point is to use a panoramic camera and adjust the subject to a camera distance of a focal length that is a suitable length to create an optical illusion that makes the objects appear to be smaller, the further away they are from the camera.
