Photography Tutorial Color Basics (1): Photography and Color
Color is everywhere, and our lives are inseparable from color. Color makes the world we perceive rich and colorful. Just because color is as common as drinking water and eating every day, most people ignore the origin and use of color. However, as the language of visual art and an important means of expression, color is especially important for photography. The camera is just a tool. Only by understanding and applying color can we capture the beautiful moments of color, better express the intention of photography, and perform better. Photography creation.
Why learning photography is inseparable from color can be explained from the following aspects:
First of all, color is a visual phenomenon, not an objective component or characteristic of matter. There is color only when there is light. People cannot feel the existence of color on a dark night, so there is no color without light. Light is a necessary condition for people to perceive the existence of color, and color comes from light. Because the objects reflect different colors of light, the colors of the objects we see are also different and change with the change of light. Light has the characteristics of waves. The wavelength of light determines the hue, and the energy of light determines the lightness and darkness of the color. The part of light waves that the human eye can perceive is called visible light, and the wavelength of visible light is approximately between 380 and 780nm. When the color vision cells of the eye receive visible light of different wavelengths, they perceive different colors. The colors are produced by the stimulation of the color vision cells by light of different frequencies.
Shade has the following characteristics:
Hue
As the name suggests, hue refers to the "appearance of color". Such as red, blue, lemon yellow, etc. Hue is the primary characteristic of color and the most accurate standard for distinguishing various colors. In the visible spectrum, human vision can perceive different colors such as red, orange, yellow, green, cyan, indigo, and violet. Different colors have their own wavelengths and frequencies. The characteristics of the hue are determined by the spectral composition of the light source and the The ratio of the radiation of various wavelengths reflected by the surface of a colored object to the human eye.
Purity
Purity refers to the degree of color saturation. The simpler the light wavelength, the higher the purity of the hue. On the contrary, the lower the purity of the hue. It represents the proportion of color components contained in a color. The greater the proportion of color components, the higher the purity of the color; the smaller the proportion of color components, the lower the purity of the color. Various monochromatic lights in the visible spectrum are the purest colors and are of ultimate purity. When a color is mixed with black, white or other colors, the purity changes.
Value
Value is the brightness of a color. Various colored objects produce light and dark colors due to differences in the amount of light they reflect. There are two situations of color brightness: one is the same hue but different brightness; the other is the different brightness of various colors. Each solid color has a corresponding brightness. Yellow has the highest brightness, blue-violet has the lowest brightness, and red and green have intermediate brightness. Changes in the brightness of a color often affect the purity. For example, when red is added to black, the brightness is reduced, and the purity is also reduced; if red is added to white, the brightness is increased, but the purity is reduced.
Color can not only cause emotional changes, but can often also express one's own culture. The character of color is the psychological effect and feeling that color gives people. The first thing a photo takes away from you is how the color makes you feel. This is its psychological effect.
The feelings given by various colors:
Red: enthusiastic, festive, warm, enterprising and enthusiastic.
Green: vitality, peace, coolness, calmness, hope.
Blue: vast, fresh, deserted, tranquil and quiet.
Yellow: noble, solemn, glorious, gentle and bright.
Cyan: strong, smooth, calm.
Orange: gorgeous, rich, sweet, and enjoyable.
Purple: deep, steady, mysterious, cold.
White: sacred, pure, quiet and immature.
Black: mystery, sadness, stability, death.
Gray: peaceful, rich, gentle and steady.
Brown: calm, honest, strict and deep.
Golden yellow: noble, elegant, gorgeous and orthodox.
Silver white: noble, elegant, soft and bright.
Magenta: gentle, earthy, frank, and peaceful.
