: cyan, magenta, and yellow. As mentioned above, the three primary colors of light can be added together to make white light. So, if an RGB value of 255,255,255 is white. If you completely remove the three primary colors of the light (rgb:0,0,0) will produce black.

So, if an RGB value of 255,255,255 is white. If you completely remove the three primary colors of the light (rgb:0,0,0) will produce black.

On the website, we are faced with the projection of light, not the light reflected back from the object, so we use the additive mode, which we call RGB. Additive method in nature, the light waves we see are reflected through the object into our retina, but the way in which it produces color is not just this one. For example, stage lighting use

This article is an optional color for use in RGB mode. ) One, intuitive panel, ...

The effect of oil painting can be divided into three steps: first of all, to determine the main color, and adjust the good shades and levels, and so on, and then use the filter and material superimposed to make the preliminary oil painting effect, and finally fine-tune the local details, enhance the oil painting effect. Original Final effect 1, adjust the photo histogram, so that the photos get accurate exposure.

In this section of the tutorial, corn will give you a detailed description of the various properties of colors and how to adjust colors effectively in PHOTOSHOP6, where some information may be a bit esoteric, but as a powerful feature of PHOTOSHOP6, you know it and will make your job more handy. PHOTOSHOP6 to color processing and adjustment is very intuitive, open the palette, pay close attention to the cursor, from a model to another model, it will always display color information. We will star

; Lena_1.getpixel (10,10))255>>> Lena_1.getpixel (10,120)) 0>>> Lena_1.getpixel (130,120))255>>> Lena_1.show ()Results:　　Mode "L":The pattern "L" is a gray image with 8 bits per pixel, 0 for black, 255 for white, and other numbers for different shades of gray. In PiL, the conversion from mode "RGB" to "L" mode is based on the following formula:L = R * 299/1000 + G * 587/1000+ B * 114/1000Below we convert the Lena image to an "L" image.　　 >>> lena_l =

shades of brightness are the maximum (255), the screen reproduce the color is the brightest white, are 0, the result is black. If you want to draw the "Begonia red" just mentioned, we should turn the red light to the brightest, the brightness of green to about 1/5, and then the brightness of blue to about 1/3, the following figure: Similarly, to get just said "add some orange in, then a little more light" color, we have to turn the green light 1 ti

Additive process ColorUse red (red), green, Blue (blue) three shades for color blending to show other colors. The more light the shade mixes, the more bright it is called the additive process color. The display of TV and computer is based on the principle of additive blending.Red (R) Green (G) Blue (B) is called the three primary colors of light.Fig. 1. Addition process ColorSubtraction process ColorBlended with blue (Cyan),

Lena image with resolution 512X512 is as follows:One, the mode "RGB" conversion to other different modes1, Mode "1"The pattern "1" is a two-value image, not black or white. But it is represented by 8 bits per pixel, 0 for black, and 255 for white. Below we convert the Lena image to a "1" image.Example:>>> fromPILImportImage>>> Lena =image.open ("d:\\code\\python\\test\\img\\lena.jpg") >>>Lena.mode'RGB'>>>Lena.getpixel ((0,0)) (197, 111, 78) >>> lena_1 = Lena.convert ("1") >>>Lena_1.mod

shades in the gray chart: RGB channel grayscale image is higher brightness, black indicates brightness is lower. White indicates the highest brightness, pure black indicates brightness is zero. CMYK channel grayscale is white to indicate that the ink content is lower, black means higher ink content, pure white means that there is no ink. Pure black means the highest ink concentration. Use this definition to see the CMYK channel grayscale, you will

talking about the color mode Do you have the feeling that a vivid and colorful image is printed through a color inkjet printer, and the color becomes dark and ugly, even though the printer is of high quality output? But before you blame your printer, I want to ask, what color format is your image? "Color is color, what's the format?" ” Yes, there are various forms of color. Open your Photoshop and look at the mode item under the Image menu, which has a long list of names, what are those? Let's g

Purple is a relatively rare color in nature. Symbolizes the feminine, represents the nobility and the luxurious, the elegance and the charm, also symbolizes the mystery and the solemn, the sacred and the romantic. On the other hand, there are loneliness and other means. Purple in the Western world of religion is a representative of the color of nobility, the archbishop wearing the robe was purple. The Purple lightness is the lowest in the color chroma. The low lightness of purple gives a dull,

channels. First you need to understand the RGB three primary colors and the principle of the channel. RGB color mode for the color mode, physicists have found that the sun's white light contains red, orange, yellow, green, green, blue, purple 7 kinds of shade, but the most basic shade of red, green, blue. If the color of the three primary colors of red, green, blue 3 kinds of light at the same time to the same amount of purity projection to the screen, that is, to become white. Al

The first to learn to do the Web page, it is not careful to use the CMYK model of the picture, and then open in the browser is x, and then find a long time to know the original page to use RGB mode, now we have to simple Photoshop grayscale, index, RGB, CMYK four mode. 　　Grayscale mode : Simple point that grayscale mode is like Black-and-white photos, all colors are in different 256 shades of gray (so in grayscale mode to fill in other color color, t

% in the Gray slider, and then switch to the RGB slider to see the value. The following 2 figures: Note If you do not turn off the color management feature, the grayscale standard in color settings may not be GrayGamma2.2, then the above equation is not true. For example, grayscale standard if is graygamma1.8,18% grayscale conversion to RGB is 218,218,218. Although there are 256 levels in grayscale, because Photoshop's grayscale slider can only enter an integer percentage, you can actu

-dimensional. Therefore, the light and shade relationship plays a vital role in the stereoscopic and level sense of the picture. Neutral Gray Grinding is the use of the principle of the skin to deepen the reduction of light. For example, how can wrinkles be seen? Because the skin folds hinder the light into the formation of shadows, you just fade the shadow area, wrinkles disappear, because there is no light and shade contrast, the use of neutral ash method for acne, freckle and so on are a tru

The color balance is similar to the optional Color command, and can be corrected for the tone of the image. The difference is that the former increases or decreases a color in the shades, and the latter increases or decreases the color content in a particular color. 1. Color balance The color balance command can change the composition of the image color. It is designed according to the principle of increasing the basic color when correcting the colo
