Light locations are a critical component of image quality

Exploiting the light according to its location on the subject can avoid many of the errors that we are used to in our pictures, and it can also give us a set of distinctive pictures with artistic impressions that go beyond the usual traditional pictures, to enter the game of shadows in a wonderful artistic field within our pictures of nature and faces at the same time.

There are many sources of light, as we know, the sun, candles, lamps, and electric lights of all kinds. The energies of these light sources are multiplied by the multiplicity of their types. So we can say that we have always considered - and in a previous issue - that light is the most important part in the photography process. We can follow up here that the direction from which the light is emitted towards the subject controls the quality of the image to a large extent, and from this standpoint we can exploit the arrangement of our positions with the position of each of the subject and the light source to obtain the images that we want. Three main things play a role here: the camera, the subject, and the source of light - and we will take the sun as a basic base for the light.

headlight (*)

The traditional rule that is often followed is that the camera is located between the sun and the subject, so that the subject is facing the sun, which in turn is behind the back of the photographer, and the three are on one straight line in this way.

This position, which some consider ideal, often leads to undesirable results... The sun shining on a subject makes it lose its purity as it reflects shadows on it in a large way. We want to use these shadows for special artistic impressions, as the result will be unsatisfactory. If the subject is a human, then one of the obvious negatives here is that he cannot open his eyes well in front of the sun. We often see pictures of people with their eyes closed. As a result of a situation of this kind, the image loses its importance and its main features represented by the eyes of the person to be photographed. .

In order to avoid this error, it is necessary to take the picture in low light conditions - the sunset and sunrise periods - but if it is necessary to take it in the noon period, it is necessary to change the position so that the light is on the side, and there are two positions of this type, each of which has different results in the side light. 45 degrees, and the side light «90 degrees. .
The side light (*) is 45 degrees, and the position here is as follows:
The position depends on forming an angle of 45 degrees between . The subject, the sun, and the camera, which is the best for portrait photography, whether inside or outside the studio, because the light does not disturb the person who intends to photograph it, nor does it leave a strong effect on the image or the film. However, this situation cannot resolve the issue of the shadows that will come in this field. One location on the face, either the shadows of the nose on the opposite cheek, or the shadows of the hair on one side of the head on the other side of the face, and here it is necessary to use a reflective plate (*) or use the flash, if we do not want to exploit the shadows for intentional artistic impressions.

The side light is 90 degrees, and the three points here form a right angle of 90 degrees, and this position is limited to those who want distinctive artistic impressions for their images, as it works to mix light with darkness, so that the side opposite the light is luminous, while the other side comes dark, and so on

The reader can be assured that images of this kind are adopted by photographers to give artistic impressions to their unconventional images. Here we must make sure of one thing, which is that the opposite side of the light is very bright and the other is dark in order to show the intended impression clearly. Herein lies the difficulty in images of this type with the back light (*) and the subject comes in the middle of the camera and the light so that the sun is directly behind the subject and the three are on a straight line. This position, which amateur photographers avoid because they believe that it will give black images that can give us distinctive images, but with the adoption of one of these two methods, the use of an orange filter or any other filter to reduce sunlight, and here we have to be convinced to obtain a picture that takes the color of the filter and either rely on a high shutter aperture 16 or 22 at a speed of 1/1000 of a second, and depending on a very slow movie, 25 aza, for example, or 64 aza at the latest. Here, the topic we choose is of paramount importance in obtaining a distinctive image.
