Use The Vanishing Points In A Photo
There are lots of little tricks that we use to photographers to convey to the viewer what interests us the observer noted in an image. One of the systems most frequently used is to resort to the perspective and the vanishing points, in order to emphasize the magnitude of a landscape, for example, or to add a sense of drama to an image.
We see how, but starting from a premise of a historical nature.
Long ago, when Photoshop did not exist (and even the camera), painters and sculptors have had many problems with perspective http://smilesmultimedia.com. If the Romanesque sculptors used to avoid the prospect in the Middle Ages almost every painter has tried to reproduce it on canvas. Attempts that are actually sold (or stabilized) with Filippo Brunelleschi, who in 1413 called a geometric method for representing perspective. In 1413, in practice, it is born (on canvas) the concept of the vanishing point: the point at which parallel lines appear to converge.
The perception of the vanishing point on the part of our brain is directly linked to the size of objects as they were “away” from the observer a painter who wants to represent in his painting a vanishing point will not have to do anything but reduce the distance between the parallel lines, which means that they converge (or almost).
In the photograph the same happens: observed for example a photograph of the two tracks below.
Rails converge at a point on the horizon is not true so much so that our brain translates it into perspective, that continues to imagine the parallel rails but adds the dimension perspective to justify the convergence of the same.
The vanishing points are real catalysts of attention, guiding the viewer’s gaze, which is why they are widely used in photography, especially by those who photograph landscapes or architecture.
Make good use of vanishing points
Not all scenes have parallel lines and vanishing points clear, so at times it is necessary to emphasize them. For example, if you want to increase the perception of an image or its drama, you can use a wide angle lens as it tends to exaggerate the angles and perspective view of a scene, especially at the edges thereof. Conversely, if there are vanishing points too obvious and would lighten a little, you can use a longer focal length (for example using the zoom).
