Lighting? Does it really make a difference during filming?
It is impossible not to think and illuminate when talking about photography, if one does not know that the word photography is associated with writing with light, it is understood that this is one of the most important precautions when capturing an image or scene.
- However.
- It is not only the amount of light that counts for a photo to be of quality.
- There are different types of light sources that end up interfering with the final result.
- In addition.
- It is also necessary to know the positioning of the light sources.
- For better photos.
Anything involving light emission can serve as a light source for photography, but obviously there are some resources that are the main ones, at first it is necessary to understand that there are specifically three types of lights, they are divided between :
By knowing how to enjoy each of these lights, you can understand that they are all part of an essential set to take good photographs.
Natural lights
Natural light sources are those that are part of the environment; the sun is the main source of natural lighting and depending on its position among objects, this lighting can be more or less intense. Other sources of natural light include stars, the moon, lightning and the Northern Lights.
Artificial lights
They are everywhere, for example
It is possible to identify them anywhere in the world and depending on each source there is a variation in temperature and also intensity, which can be more or less large.
Ambient lighting
Ambient lighting, on the other hand, is one in which control is difficult and can involve both natural and artificial sources.
The photographer usually has no means to manipulate or influence. An example of this is a photo that should be taken on the street at night, and where is a street lamp ?, it cannot be turned off, nor configured to turn off. , so it’s an ambient light source because it’s part of that place.
For this reason, most photos are taken in photographic studios, because it is possible to control the lighting.
Object color
The color of the object represents the color of the light that allows the eye to see through objects. In addition, color changes also depend on the wavelength.
Quantitative interpretation and color definition for photography
Each color has a number of properties that allow to vary its final appearance, the human being can perceive several colors, however, it is difficult to mark exactly specific colors and in this sense the quantitative part comes into play.
Nuance
The hue is the pure state of the color, without having any white or black, is associated with the length of a dominant wave, the mixture of light waves, so it is defined as a color attribute that allows humans not only to see, but also to distinguish blue from red, and that also refers to the path that makes a tone travel on both sides of a chrome circle. Therefore, bluish green and bluish green are part of different arrays of the green color itself. .
The three parent arrays are represented by the three primary colors, when merged you can get other matrices or colors. Two colors can be complementary to each other, when faced, in the matrix circle which is the same chromatic circle.
Saturation
Saturation is also called chroma, this concept has a representation of the purity and intensity of a particular color, that is, it indicates the paleness or vivacity of the same color and can also be related to the width of light that is displayed.
The pure colors of the spectrum show that they are completely saturated, an intense color is a very bright color, that is, the more saturated a certain color is, the greater the impression that the object is in motion.
Another important detail is that the higher the amount of gray, or the more neutral it is, the less bright and saturated any changes made to a pure color will be, the more automatically there will be a decrease in the saturation of the color to be printed. in photography, for example, it is common to say that red is very saturated when there is a reference of a rich and bright red, however, when reference is made to a shade of color that has a certain value of gray, it is called less saturated. .
It is said that there is less saturation when adding the add-in to the color circle.
For a color to be unsaturated or have a variation in its value, it must be mixed with black and white grays of equal value, an intense color like blue will lose its saturation as white is added, becoming celestial.
Another way not to saturate a color (in the photo), should be mixed with its complement, because there is a neutralization, it is possible to define a neutral color, in which the saturation is not clearly perceived, therefore, the intensity of a color will be determined by its character between light or low.
Clarity/brightness/value
This definition is widely used to describe and define how dark, light, or bright a color can be in the photo. Depending on the amount of light reflected.
Brightness is defined by the amount of darkness that a color has, that is, parts of the same color, can have different values (or also called contrast value) and has to do with different parts of space, what does that mean?
That a gradual change in the value of a color, can generate in the photo the definition of contours and the continuity of objects in a given space.
The more dark light sources you add, the lower the intensity values you get, i. e. the colors of the photos and the definition of the objects photographed will be less intense.
And the whiter there are to define the colors and objects in a photograph, the more its clarity intensifies.
