Our Ring Light Foldable Wholesale, let's share with you the basics of light that new photographers must learn.

　　Light and shadow are the most basic basis for us to transmit pictures, visual information and other shapes. Only light can create shadows, and only light can have overall perception. To really understand the use of light means to memorize it like the relationship between aperture and shutter, to use them to create, to realize ideas, and to understand the basics of these lights, you can use them in any scene. Let's take a look at some basic vocabulary for using light: Key light: The light that dominates the lighting, also often referred to as "key light" or "modeling light". The key light determines the "tone" (high key or low key) of the film, and its position also creates the sculpted outline created by the highlights and shadows.

　　Fill light: The light that plays an auxiliary role on the screen is called fill light or fill light. The level of detail of each part of the portrait on the screen is controlled by fill light. Auxiliary light is divided into Yang auxiliary light and Yin auxiliary light. The role of the supplementary yang light is to increase the transition level between the light and dark boundary between the bright part and the dark part; the role of the supplementary yin light is to increase the level of detail in the dark part.

　　Light ratio: The light ratio is the ratio of the intensity of the main light to the auxiliary light. When the difference between the two is small, it is called a low-key lighting shot; a light ratio of 2:1 means that the main light is twice as strong as the fill light, and the shadows caused by the key light are basically offset by the fill light. When the intensity of the main light and the auxiliary light is very different, it is called high-key lighting shooting; a certain shadow in the photo can make the scene retain a sense of depth.

　　Luminosity: Luminosity is the general term for the luminous intensity of the light source and the illuminance of the light on the surface of the object and the brightness of the surface of the object (the luminous intensity of the light source and the illumination distance affect the illuminance; the size of the illuminance and the color of the surface of the object affect the brightness). In photography, luminosity is directly related to exposure. Compositionally speaking, exposure is closely related to the reproduction of tone or color. Rich tones and accurate color reproduction presuppose accurate exposure. Conscious overexposure and underexposure also need to be based on accurate exposure. Therefore, mastering the basic skills of luminosity and accurate exposure can actively control the tone, color and contrast of the subject.

　　Light position: Light position refers to the position of the light source relative to the subject, that is, the direction and angle of the light. The same object produces different light and dark modeling effects under different light levels.
