Lenses - Filters - Raw Film - Optics

Considering that the camera lens is a primitive mechanical part when compared to the human eye, some of the most dramatic effects can be created in the image by distortion in the photographic process itself. Especially in size and distance, where the lens cannot respond psychologically, change something, and continue to literally record things (1. 20) For example, things that are placed close to the lens appear larger than things that are placed further away. In the shot that we previously referred to in the movie - Citizen Kane - which was filmed by deep focal length, the poison bottle appears to be larger than Kane himself because it is located directly in front of the lens while Kane stands far from the lens. The context of the scene makes us understand that the difference in size is not literal, of course, except that Wells He was able to communicate this symbolic relationship to us through the distortion caused by the lens. Realistic directors like to use "normal" lenses in order to Reducing distortion to a minimum, such lenses depict objects roughly as they are seen by the human eye. Impressionist directors tend to favor lenses and filters that alter the surface of reality. These optical modulators deepen some features and hide some of them. Cloud formations, for example, can be exaggerated in portraying them to a terrifying degree, and their spread can be increased to appear soft by using different types of filters, and different densities in shape, color and light can be created by using certain optical modulators. There are a large number of different lenses, but most of them fall under three main categories:
Distortionless normal range, telephoto, and obtuse angle lenses .
A photographer from Asad Keema photographing a telephoto lens (telephoto) mostly used to get magnified shots of objects from very long distances. For example, there is no one who wants to get close to him with a magnifying glass. In such cases, the telephoto lens is used to ensure the safety of the photographer at the time when we get the required enlarged shot. And telephoto lenses enable the photographer to be precise and careful. The close-up lens allows the photographer to remain hidden in a car, for example, while he takes close-up shots according to his needs through the front or rear window of the car. As a result, the lens works as a telescope, and the large focal length number means a small angle of vision, and the ability of the lens to zoom in has nothing to do with the number directly. allow

Tele lenses (telephoto) give us multiple side effects that are sometimes exploited by directors for psychological purposes. The sharpest long lenses are clear in one plane at a certain distance (1 - 22) and the objects that are placed in front of or behind this level appear blurry and indistinct. The longer the length of the lens, the more sensitive it is to distances, and the lenses of very long lengths look like objects that are placed at a distance of a few A decade of plane located in the chosen point of sharpness - featureless.This deliberate gouache of planes in the background or foreground of the picture or in both can give us a strong pictorial effect.In the movie The Gardens of Finzi Continents for example the wealthy and myopic Jewish family in the title of the film is depicted in this way This photographic gouache becomes a metaphor for the innocence of the family and their need for political farsightedness.
