Between the human eye, which produces pictures, and the camera, there are several similarities. Since the human eye is in the form of a sphere, the image is collected on the retina, not in a plane, on a sphere. The human eye is oval-shaped. In the human eye, the cornea and oculus perform this role. The human eye is a superb “device” Our eyes easily adjust to make clear images when the objects are too far or too near in dark or bright conditions. The distance in the human eye between the lens and the retina is constant. When looking straight ahead, each eye of a human has a 95-degree field of view from the nose to the outside. The field that each lens sees from the same distance when looking at the same object varies with the focal length. Perspective is the transfer of the object’s appearance and space on paper using certain methods to give a two-dimensional surface a three-dimensional visual effect. In cameras, the lens can collect at its focal point the image of a particular area of the subject.
My purpose in this report is to explain how photography or video artists use their eyes before using a camera to perform their art. To learn how they have integrated themselves with the equipment used, and to transfer this. This is kind of like the difference between looking and seeing. Many artists dealing with visual arts uses the term ‘to see’. I have adverted the reason for using this idiom and aim to explain it as much as I can.
The Relationship of Eye and Camera in Perspective Context
With regard to the field of vision of any living thing, it is difficult to provide a single and universal answer; because within each living population there is a wide variation, and thus those ranges from person to individual can differ significantly. However, with the results of certain experiments, it could be possible to draw up a general structure. The human eye is oval-shaped. Its angles are horizontally at 178o – vertically at 135o. 60 degrees upwards and 75 degrees downwards are the vertical viewing angle. When looking straight ahead, each eye of a human has a 95-degree field of view from the nose to the outside.
The human eye is a superb “device” Our eyes easily adjust to make clear images when the objects are too far or too near in dark or bright conditions. The right adjustments must be made in the camera to take amazing pictures. Between the human eye, which produces pictures, and the camera, there are several similarities.
The light from the object must be focused on a light-detecting surface in order to create a clear picture of an object. In the human eye, the cornea and oculus perform this role. The lens works the same in the cameras. The distance in the human eye between the lens and the retina is constant. For this purpose, the lens changes shape thanks to the muscles as the distance of an object changes, in order to produce a clear picture. When the muscles are relaxed, the lens is flatter, and its sphericity increases when it contracts. Thus, the degree of refraction of light varies.
In cameras, the lens can collect at its focal point the image of a particular area of the subject. The angle that shows the part of this region created by the lens that falls on the plane or sensor of the film is called the angle of view of the lens. The higher the focal length, the smaller the viewing angle. The cameras create a frame at a certain angle according to the lenses they use. The field that each lens sees from the same distance when looking at the same object varies with the focal length.
Perspective is the transfer of the object’s appearance and space on paper using certain methods to give a two-dimensional surface a three-dimensional visual effect. Objects and space can create various forms of appearance from different perspectives. In the simplest terms, their appearance becomes smaller and different from their genuine appearance as the objects move away. This differentiation can be expressed both with perspective science and drawing as optics and mathematics.
Since the human eye is in the form of a sphere, the image is collected on the retina, not in a plane, on a sphere. It sees a 2-degree segment with a flat, distorted perspective roughly in the centre.
Memorization of the Image Perspective
Memory can belong to both a person and a society. Memory is the sum of valuable and memorable things in terms of meaning. All of the pasts cannot be remembered, and some things are forgotten. (Al, 2015, s. 27).
If human beings forget, the image is worthless. Since it is difficult to see how much and how much the picture exposes the truth. At this point, man and his memory are of primary importance. The memory, though, retains what it treats as important and forgets other people, namely, what they deem to be unimportant. However, the photo draws it to the unforgettable hand and adds value to or without exception to everything. So, it is almost unforgettable all you show.
Human memory comes into play here. Memory tries to memorize the image. The advantage of the artists here; learning how to use their memorization. The angle at which the camera captures the image, the distance, light intensity, etc. such things are remembered in enough detail to come to life in the eyes of the artist.
The image always contains the possibility to be seen or seen. Thus “to be visible is to be there: not to be there, to be invisible.” (John, 2008, s. 223) Consider this interpretation of Berger, if we touch upon the way of seeing the photograph and video artists; it turns out how strong or how well educated visual memory should be. For example, a cameraman travels and explores the area where he will be shooting before he starts shooting. It visualizes which angles to use. This requires the full use of visual memory. Because the cameraman is trained and experienced enough to understand which lens to use during exploration and how this lens will look on the camera sensor.
The relationship between the camera and the perspective of the human eye emerges right here. It should not be limited to just video. The same experiences and training are required in drawing, photography, and even graphic designs. The ‘to see’ statement of the artists actually arises here.
To sum up, the relationship between the camera and the human eye, which we examine in the context of perspective, is superficially composed of the above.
According to the perspective context, artists who are interested in visual arts develop their memory with visuals again. In this way, they perform the act of ‘to see’ their perspective angles or in their own words by using their visual memories they have developed.
The preview with the camera, drawing, or photo appears as the ‘to see’ action occurs. In fact, it is necessary to mention visual memory. However, the relationship in this context is only summarized in the report content.
It is a topic that will be talked about for hours and pages of articles on. If it is necessary, to sum up, the report prepared on this subject; looking is often insufficient, the important thing is to see. But if there is no experience, memorization, or content from the visible things, there is no point in seeing.
