Feel the light "taste" about the importance of light on photography2017-10-31 17:46:14
The photographer's "God" should be light, for there is no light, there is no photography art and no light. Even if we have the best equipment and ideas, we can not see the result. Our imagination is like the wings of a bird, and the light is the wind that holds up the wings. Barbara Morgan said: "Light gave me creative shapes and scripts that are why I became a photographer." The balance of photography and its interaction with light and shadow make up the fundamentals of photography. As a photographer, pre-shooting is to capture light, while post-processing is to adjust the intensity and distribution of light on the photos.
The term photography is derived from the word photo and graph in ancient Greek. In a photo, light and shadow, reflections, flare, glow, and even the light source itself can be the subject of photography. Light intensity, light source size, shape, temperature and light direction, quality, hue, can affect the photo's which performed. Any changes in the parameters of the light or the impact of the environment, will make the content of the work to change. In a photo, the brightness is not only the light in the reality itself, but also the steering wheel of the photographer to control the subject matter. Brightness is emotional, especially in black and white photography, as the only modeling tool on the screen, controlling the brightness of the light, this magic is not great?
Human beings are light-sensitive animals. This is not to say that mankind will produce chemical changes like films, but people are very subjective in judging brightness. Brightness in photography has never been a simple problem of light and shade, each brightness will give the screen a specific emotional color. In the picture, the brightness will have a very big impact on people's emotional judgments.
In the pre-shooting, light comes from natural light sources such as the sun, the moon, the stars, and artificial light sources. The control of brightness is mainly achieved by the exposure control and the light source layout, and the camera merely records and can not create a non-existent light source. In post-production, the light source properties can be changed through brightness control, even creating non-existent light sources. Of course, creating a light source requires a full understanding of the light, which is the power of later.
Photography inherited the rich resources of the history of western painting. The precise perspective and the relationship between light and shadow of the classical art of modeling were flourished in photography and were scientifically confirmed. Therefore, the history of western photography standing on the strong foundation of painting can be smoothly developed by focusing on the technology. A photographer can easily gain aesthetic approval as long as it is clearly not in violation of the traditional aesthetic rules. In the processing of photographic elements, it can be said that the restraint of technology is far more serious than the aesthetic bondage.
In order to understand the importance of light for photographic modeling, let's take a look at how traditional paintings use light to create a sense of reality. Early masters of painting were familiar with the manufacture and control of light sources. Rembrandt Harmenszoon van Rijn, Leonardo da Vinci, Michelangelo Merisi da Caravaggio and Jean Auguste Dominique Ingres were among the few Mastering this ability to create light and shade, the rationality of the light source in their paintings is the result of in-depth observation of the effects of real light transmission.
In Simone Pignoni's "The Death of San Pietro Milia," this dramatic traditional approach to lighting comes from the understanding of natural light.
Modern artists such as Pablo Ruiz Picasso and Salvador Dali used surrealistic absurdity of light to create a surrealistic presence that people believe The possibility of light in the real world, but also doubts the rationality of the object's shape in this light, the resulting deviations from reality are enchanting.
In photography, the pre-exposure exposure control is beyond the scope of this book and will not be described here. In post-processing, any brightness distribution on the photograph will be the result of conscious control. Compared with the previous shooting process, the latter part of the controllability greatly increased, image processing software for photo brightness control provides the most basic and most abundant features.
In Inglês's work The Bathing Woman of Vapenson, a uniform and clear light that looks like a global rendering is based on a profound observation of light refraction.
Pre-camera exposure control is mainly done by adjusting the shutter speed, aperture and sensitivity of the camera. Under artificial light conditions, the brightness control of the flash light is also important. For a variety of reasons, a photograph taken is not equal to the work in the book's meaning, and the photograph taken in the earlier period is more likely to be acquired than the photograph taken later. In LR and PS, there are powerful and rich features that focus on brightness control. If you have not played the film, it does not matter, do not understand the principle of exposure, do not know how to calculate EV, this is not a problem. Creative photography is not the most concerned about the exposure of the data itself, but the psychological needs of the exposure, there is no reason for the exposure is just a meaningless number Bale, exposure is the soul.
