"What is Blending Mode?"
In the realm of digital design, photography, and various software applications, the term "blending mode" plays a crucial role. In English, it is directly called "blending mode".
I. Definition and Basic Concept
Blending mode refers to a set of algorithms or rules that determine how two or more layers of content interact with each other when combined. For example, in graphic design software like Adobe Photoshop, when you have a layer with an image and another layer with text or another graphic, the blending mode you choose will define how these two elements blend together.

II. Common Blending Modes and Their Effects
1、Normal Mode
- This is the most basic blending mode. In normal mode, the pixels on the top layer simply overwrite the pixels on the layers below. There is no special blending effect. It is like stacking transparent sheets of paper on top of each other, and the top sheet completely obscures what is beneath it, unless the top layer has some transparency value set. For example, if you have a solid color layer on top of an image layer in normal mode with 100% opacity, you will only see the solid color. But if the opacity is reduced, you can start to see the underlying image showing through.
2、Multiply Mode
- Multiply mode multiplies the color values of the pixels on the top layer with the corresponding pixels on the underlying layer. This usually results in a darker effect. If you have a white layer on top in multiply mode, it has no effect on the underlying layer because white has a value of 1 (in terms of color multiplication), and multiplying by 1 doesn't change the value. However, if you have a black layer (which has a value of 0), it will make the underlying layer completely black. For instance, when you want to create a shadow effect on an object in a digital illustration, you can use a multiply mode with a semi - transparent dark color layer.
3、Screen Mode

- Screen mode is the opposite of multiply mode. It lightens the result by inverting the colors, multiplying them, and then inverting the result again. This is useful for creating highlights or for making an image look brighter when combined with another layer. For example, if you have a light - colored layer on top in screen mode over a darker image, it will brighten up the areas where the light - colored layer overlaps.
4、Overlay Mode
- Overlay mode combines the effects of multiply and screen modes. It multiplies or screens the colors depending on the underlying layer's color value. If the underlying layer is dark, it behaves more like multiply mode, darkening the top layer. If the underlying layer is light, it behaves more like screen mode, lightening the top layer. This mode is often used to enhance the contrast and color saturation of an image while still maintaining some of the original details.
III. Applications in Different Fields
1、Digital Photography
- Blending modes are used to enhance and retouch photos. For example, a photographer might use a soft - light blending mode to add a warm glow to a portrait. By creating a new layer with a warm - colored tint and applying the soft - light blending mode, the skin tones can look more flattering and the overall mood of the photo can be enhanced. Another application is in creating composite images. If a photographer wants to combine two different exposures of the same scene (e.g., one for the highlights and one for the shadows), they can use blending modes to merge the two images seamlessly.

2、Graphic Design
- In graphic design, blending modes are essential for creating unique visual effects. Designers use them to create gradients that blend smoothly with background images, to add texture to flat - looking elements, or to create interesting typographic effects. For example, by using a difference blending mode on a text layer over an image layer, a designer can create an edgy and modern look where the text appears to be interacting with the image in an unexpected way.
3、Video Editing
- In video editing software, blending modes are used to create transitions between scenes, to add special effects to video footage, or to composite multiple video layers. For example, a fade - in or fade - out effect can be created by using a blending mode on a semi - transparent layer that gradually appears or disappears over the main video layer.
In conclusion, blending mode is a powerful concept in the digital media world. Its various types and applications offer designers, photographers, and video editors a wide range of creative possibilities to achieve their desired visual effects. Understanding the different blending modes and how they work is an important step in mastering digital media creation tools.
