Three primary colors of photography

The core principles of color matching in the later period: three primary colors/adjacent colors/complementary colors, and basic knowledge of colors.

-

? The three primary colors of mixed color are red, yellow and blue; The three primary colors of light mixing are red, green and blue.

1. Optical mixed color phase ring is the main interpretation software, which can't explain color.

2. Mixed color is the color that the light is projected on the object and reflected in our eyes by the object, which means that mixed color is the color we actually see, and all color theories are based on mixed color.

The above is the color circle that explains the correct color. I see that the color circles in many tutorials are wrong, as shown below.

The above pictures are mainly used to explain Photoshop software, and have nothing to do with color matching. Why do so many people follow suit and even some famous teachers make mistakes? Because most teachers are integrated with online tutorials, many friends who spent more than 10 thousand yuan in their later years have learned a lot of online tutorials. I'm not really alarmist, nor is it for marketing or advertising. You can ask your friends who have studied around you if everything he has learned is available in Baidu.

A few days ago, I shared a typical error tutorial. I made a comment in the tutorial. The tutorial is as follows.

Many so-called "teachers" say so, even teachers with adobe certification say so, misleading many people.

1, color phase loop

Hue: it is the standard we use to distinguish different colors. For example, when we say red, yellow, blue and green, we mean hue.

Color ring is to arrange colors in the order in which the spectrum appears in nature. According to the degree of subdivision, it can be divided into twelve color rings and twenty color rings.

This color ring is a light mixed color ring. Many teachers hold it to talk about color, and the logic is clear and self-evident. It looks very reasonable and professional, just like those who talk about soft light retouching of gray layer, holding soft light calculation formula to prove soft light retouching of gray layer. People who don't know the soft light calculation formula may feel very professional, and those who know it will know that it's just integrating online tutorials to sell money.

1. Optical mixed color phase ring is mainly used to explain software, not color.

2. Mixed color is the color that the light is projected on the object and reflected in our eyes by the object, which means that mixed color is the color we actually see, and all color theories are based on mixed color.

If the color ring is wrong, then the theory of explaining color with color ring is also wrong.

2. Adjacent colors, contrasting colors and complementary colors

Adjacent colors: similar hue, consistent cold and warm attributes, unified and harmonious tone and consistent emotional characteristics.

Contrast color: two colors that can be clearly distinguished together give people a sense of repulsion, which is called contrast color.

The so-called adjacent color and contrast color are based on the color ring of mixed color. If the above picture is wrong, then these complementary colors and contrast colors are wrong. The author looks very professional, too. I am afraid of this kind of article. It was wrong. After reading it, I think it's very professional if I don't understand it.

◆ The difference between adjacent colors on the color phase ring is 0-60? Color.

◆ Is the contrast color on the color ring different 120? - 180? Color.

◆ * The color with strong contrast is called complementary color, which is represented by the distance of 180 on the color phase ring? These colors are complementary.

Therefore, when analyzing the color relationship in photos, if you are not skilled in the use of colors, you can judge by comparing the color phase rings.

The color circle is wrong, except the adjacent color, all other knowledge is wrong!

(1) If the color distribution of the photo itself is relatively simple, we adopt the unified tone method:

Find a main color tone and shift similar colors to the main color tone until they are shifted to the adjacent color range of the main color tone. If the colors are too far apart, please reduce their saturation.

(2) If the color difference of the photo itself is relatively large, we use the contrast enhancement method:

Enhance the contrast if there is contrast. Find two main colors of contrasting colors, and the other colors depend on the two main colors.

1, unified tone method

If the color distribution of the photo itself is relatively simple, unifying the tone of the photo can make the overall color not messy, highlight the theme, and give people visual comfort.

First, give an example

Observe the above two movie screenshots, which belong to the situation of uniform tone, and the color picture is very comfortable, setting off the emotions you want to express.

There are many such tutorials, which seem reasonable, but the overall color is due to the light source, not the unity of color matching or tone.

The color of a picture should be considered: light source, light and shadow, inherent color and environmental color, rather than these color bases, contrast colors, complementary colors and adjacent colors. These color knowledge is only props to help students train, not to create with these things.

How to operate? ① Choose the main color; ② Adjust other colors in the photo to the main color through the HSL adjustment panel in PS or LR; (3) The saturation of colors that are quite different from the main color should be reduced.

Special case: black and white processing

There is a saying in the photography circle that "it is not enough, and black and white come together." In the photos with some messy colors and it is difficult to find the main color, black and white can often increase the artistic sense of the photos.

Take the above picture as an example. After black and white processing, the messy colors in the photo are removed, and the photo is transparent, which enhances the texture of the picture.

Black and white is not for artistic sense! Because black and white photos look good. Most people like black and white photos because black and white belong to the rest area visually, and their eyes will not be so tired when they look at black and white.

Processing into black and white can not remove the messy colors, because the eyes are the visual center of the picture, and the points are also the places where the vision is more focused.

2. Enhance the contrast method

If the color distribution contrast of the photo itself is relatively large, the usual treatment method is to deal with the contrast effect more strongly, which can often increase the expressive force and tension of the photo.

First, give an example

Take the contrast between cold and warm as an example. Cold and warm contrast is a classic contrast technique in photography. Generally speaking:

◇ Cool colors include: blue, cyan, green, purple, etc.

◇ Warm colors include: red, yellow, orange and magenta are all warm colors.

There is a common method to compare cool colors with warm colors, which is to add warm colors in the bright parts where sunlight can shine and cool colors in the shadow areas where sunlight can't shine.

As shown in the above picture, the peaks and grasslands on the lower right are all places where the sun sets and the sun shines golden yellow; The rest of the area belongs to the shadow-free area, with a faint blue-green color.

Through the contrast between cold and warm, the saturation of the two colors is visually enhanced, and the tension and three-dimensional sense of the picture are increased.

Although the result of this paragraph is ok, it is not so understood. Because of the light source, not for the tension and three-dimensional sense of the picture. This is the relationship between cold and warm.

B, enhance the contrast of operation

Take two-color contrast as an example, find two main contrast tones, and bring the other colors closer. Three-color contrast and four-color contrast are the same.

If the above picture is a contrast between magenta and blue, other bright parts can be close to magenta, dark parts can be close to blue, and the color saturation in the middle part can be reduced. This will make the contrast clearer and the theme more prominent.

note:

(1) Pay attention to the proper use of achromatic colors (black, white, gray) or the same color as the main color when matching contrast colors.

⑵ The contrast of complementary colors is very strong. If it is not necessary for expression, use it with caution.

The colors of the color ring don't match! At this time, the contrast color and the complementary color are wrong. How to use color matching? The principle doesn't match the operation, will the result be right? Is the contrast color used like this? When complementary colors are used, they can be reconciled by area, purity and so on. Why use it with caution? I don't know how to reconcile it.

The color ring is wrong, the contrast color and complementary color are wrong, and the color matching idea is wrong.

Color matching needs to consider telling a story according to time, place, people, background and events, what is the temperament of this story, and setting off the picture with colors according to the expression of the picture.
