The theoretical basis of color in photo processing

Photo Processing network has been lack of relevant theoretical basic knowledge, the major domestic design, photography site can not find a photo processing color-related basic theoretical knowledge, therefore, through the collection and inspection and collation, and then digest and summary, wrote the "Photo processing in the color feast." Also hope that all the students teacher corrected and supplemented.

This series of tutorials contains three major chapters:

The first chapter: the Family----The theory basis of color in photo processing.

First of all, we declare that many of the color theories and illustrations listed below are not original, I just gather the knowledge and work, combined with my understanding and digestion of the results, summed up some learning experience and experience, do not dare to enjoy, take out on the photo processing network, I hope my study results summed up to give everyone a little help, Together and everyone to progress together. I also thank the part of the tutorial I used the name of the author in order to share and study together to publish the wonderful works!

This learning theory may be very boring, if you think the fast asleep, it is best not to continue to see, this is the experience of C-Hao, it is not easy to find these theoretical foundations on the Internet, and to appreciate and digest them carefully. I've seen it 6 times, and 4 of them have a wet keyboard, eye drops with 93 ml (120 ml), cold snacks and hot, hot and cold number of times is not clear ..., so by girlfriend forced to divorce, fortunately, fortunately no marriage license, not from ... As if the farther away ...

Like the first step in processing a photograph is to copy the background layer, as is customary; to understand and use color in photo processing, we still have to master some basic color knowledge; (boring begins ...) ）

Section I: The basic composition of color:

(1) Three primary colors: red, yellow, blue,

When you are in primary school, you may know the three primary colors: red, yellow, blue, and you are now used to display, is still red, yellow, blue three primary colors.

By definition, the primary color is the ability to synthesize the basic colors of any other color according to a number of rules. But many members would say, "I have black in my printer." I pour ... this is a drag. C-Hao can pull it away. Ah, the difference between the light color and the object's nature, led to the color theory of positive and negative color display theory, but this is not the scope of our discussion today, we only study the color model of the three primary colors: red, yellow, blue. As long as we know the basic three primary colors is their three families on the line.

I faint ..., red, yellow, blue three primary colors, who do not know ah, white speak a pass .... ）

The C-Hao now puts three primary colors into the triangle in the image below, and then mixes the adjacent colors to produce a very simple chromatogram:

(Figure 001)

(2) Contrast color (also known as complementary color or complementary color)

Contrast color is very simple, very good understanding, is the above figure (001) The diameter of the circle relative two color is the contrast color.

For example: Red contrast color is green, yellow contrast color is purple, blue and purple contrast color is yellow orange.

It goes without saying that the contrasting color of the black is white. Good contrast color is bad, positive contrast color is reversed ... (It's getting off the topic ...!) ）

In the photo selection of contrasting colors to match, the screen gives a strong sense of impact,

Take a look at the contrast color application photos, see the beautiful baby is not easy to sleep ..., the first statement: No matter what reason, do not drool oh.

(3) Approximate color (also known as similar color, harmonic color)

We understand intuitively from the above figure (001) that the approximate color is the 6 color adjacent to it.

For example: red color is red yellow, orange and purple, Lan Zi and so on.

For example: Green's approximate color is yellow green, yellow and blue green, blue and so on.

For example: Lan Zi of the approximate color is blue, blue and green and purple, purple and so on.

Now the family has come to the conclusion that the approximate color of a color does not contain its contrasting pigments.

For example: Yellow contrast color is purple, then, we just understand: do not contain purple color is the approximate color of yellow.

In the photo with the color of the approximate color to match, the overall picture can achieve harmony and integration of color, rich and harmonious.

Let's take a look at the example figure (003) (image from the network)
