Prospective Distortion In Photography
Let’s now look at practically how to apply perspective to our photographs in order to make the final effect more realistic. The point we have to play is the difference in size between the objects we see in the foreground (larger) and the farthest ones (smaller ones).
Let’s make an example of a road the lines that delimit the roadway tend to converge, as in the example of the photo.
In reality, however, our brain knows it is not so sewa lcd proyektor semarang, it knows that the lines do not unite but are parallel. And he knows that the lines seem to converge as they move away from us. Banally, to deceive the human brain again by using a 2-dimensional surface (like the picture above), just play with the converging lines to give a sense of depth more or less marked to what we want to photograph.
The easiest trick to give a sense of depth to the scene is to approach the camera to the subject we want to photograph. In fact, it approaches the camera as it increases the perspective distortion as you move away from the subject and this distortion is reduced. Do you have those faces that you get when you shoot some one inches In that case, prospective distortion is so exaggerated that the whole picture is distorted.
To convey greater depth to the scene, zoom in and zoom in to the subject to be photographed. Conversely, if we want to mitigate perspective, move away and act on the zoom. In both cases we will have objects of the same size MA but the perspective lines will be different more convergent in the first case, less in the second case. Be aware that the proportions are distorted not only on the lines but also on the rest of the scene nearby objects will be larger than distant objects. So look not to ruin the scene.
Up to here we talked well of prospective distortion. In the next article, however, we will address the problem introduced by prospective distortion, that is, the exaggerated perspective that in some cases we will give the photographs, distorting the image. Especially when photographing architectural objects or palaces.
The third way is to use software embedded in some digital reflexes like the D5000 (we’ll see in detail how distortion correction works in another article). Suffice it to know that you can access a distortion correction feature from the retouch menu. Image editing is done directly in the camera (eye to use RAW format) and the effect is certainly interesting in the photo, a comparison of a perspective-distorted photo (bottom-up) and the same Corrected by the Nikon D5000.
