Detailed analysis of the blending mode principle of Photoshop

If you want to use Photoshop often, then you need to understand a simple but not easy to understand feature of Photoshop--blending mode. This is a very easy to ignore feature in many of Photoshop's cool features, but after reading this article, hopefully it will attract your attention.

　　Where is the blending mode?

The biggest reason why a blending mode is easy to ignore is its position--in the corner of the upper right of the layer panel.

　　What is the blending mode?

You can divide the blending modes into different categories by grouping them in a drop-down menu: Dimming mode, dimming mode, saturation mode, difference set mode, and color mode.

Now that you know the classification of mixed patterns, it's easy to understand when to use the relevant patterns to achieve the desired results.

　　When do I use blending mode?

Blending modes have a very wide range of uses, and when you learn the blending mode, the ready-made photo filters seem redundant. Let's take a look at an example of using blending mode to adjust photo tones:

We can create a new layer above the original picture, fill the color, and then set the blending mode to fit the hue we want, which can replace hue/saturation or other photo filters. After blending mode is selected, you can use the up and down arrows on your keyboard to quickly adjust the different modes.

Blending mode is not modified, and it turns out that you don't need these options, just change the opacity and padding of the layer. If you feel that the effect of each blending mode is unsatisfactory, then you can use the layer opacity and fill options.

As with the mixed-mode name, you can mix multiple layers to create a variety of amazing effects.

　　1. Normal mode

In normal mode, the display of the blend color is related to the opacity setting. When "opacity" is 100%, which means completely opaque, "the pixel of the result color will be entirely replaced by the" blend color "used, and when opacity is less than 100%, the color of the blend color is displayed through the colors used, depending on the opacity setting and the color of the" base colors, " The following illustration shows the effect of setting opacity to 60%.

　　2. Dissolution mode (dissolve)

In dissolve mode, it is primarily when you edit or draw each pixel to make it a "result color." However, depending on the opacity of any pixel position, the result color is randomly replaced by the pixels of the base color or blend color. Therefore, the "dissolve" mode is best to work with some of the shader tools in Photoshop, such as the brush, clone stamp, eraser tool, and so on, or you can use text. When a blend color has no feathering edges and has a certain degree of transparency, the blend color is dissolved into the base color. If the blend color has no feathering edges, and opacity is 100%, then the dissolve mode has no effect. The following figure shows the effect of setting the opacity of the blend color to 50%, otherwise the blend and result colors will not make much difference, except that the edges are slightly different.

　　3. Dimming mode (darken)

In Dim mode, view the color information in each channel and select the darker color in base or blend color as the result color. Pixels brighter than the blend color are replaced, and pixels that are darker than the blend color remain unchanged. Dimming mode causes the color lighter than the background color to be removed from the result color, as shown in the following illustration, where the bright sky is replaced by the color of the darker glass.

　　4. Multiply the bottom pattern (Multiply)

In the multiply mode, view the color information in each channel and compound the base colors with the blend color. The result color is always the darker color. Any color combined with black produces black. Any color with white compound remains unchanged. When painting with a color other than black or white, a continuous stroke drawn by the drawing tool produces a gradually darkening gradient color. In fact, the "multiply" mode is from "base color" minus the "mixed color" of the brightness value, get the final "result color." If you use a lighter color in the "multiply" mode, it has no effect on the image's "result color." Using a "multiply" pattern, you can create a slide effect that penetrates a layer of light. In fact, the color of the "base colors" is multiplied by the value of the color of the blend color, and then divided by 255, the color value of the result color is obtained. For example, red and yellow "result color" is orange, red and green "result color" is brown, red and blue "result color" is purple and so on.
