Background design is usually to meet the following requirements: 1. Highlight the background of the subject because it is not the most important thing in the picture, it is located at the last layer of all layers, so the background should not steal the limelight of the subject, but set off the subject to make it more visually impactful, more prominent and more beautiful. How to highlight the subject with the background? In fact, it is necessary to create a strong contrast. For example, the background and the subject in the following figure are in a contrasting color: the following figure is a comparison between simplicity and simplicity: the following figure is a comparison between dark color and light color: many designers like to make the background very complicated and fancy, so that the subject is not highlighted, as shown in the following figure: In fact, our focus should be on the subject, so we need to make the background a little simpler and the contrast with the text more obvious, and the subject will naturally be highlighted. Tip: Although to highlight the subject, don't let the background have nothing to do with the subject. 2. Increase the sense of space If the sense of space in the picture is strong, it will appear more stereoscopic and hierarchical, and some things will be completely displayed in the picture, which is very suitable for using a background with a sense of space, such as a tomato placed alone. Then the usual treatment method is to make it stand on the "ground" because it has light on it, so there will be a projection, and the ground will show a change of depth because of the relationship between the front and the back, so as to treat the whole. Such a background is a background with a sense of space. If the background of the above picture is made flat, the sense of space in the picture will disappear and the overall effect will be much worse. Most advertising designs with symbolic visual subjects will use a spatial background. Tip: Taking a picture with a sense of space as the background is also a common way to enhance the sense of space in the picture. 3. Enrich the picture Many times, the main body of the picture is not suitable or can't occupy too much layout space, which may lead to a thin picture. At this time, using a suitable background can also solve this problem. For example, the picture below is a little sparse because the background is too simple. So we need to add a little shading to this background. Of course, the graphics of shading should be consistent with the main body in tonality or meaning. For example, the product in the above picture is canvas shoes, so we can use a picture of a square as the shading of the background. ▲ After the background is supplemented, the overall feeling of the picture is also enriched a lot. There is a very simple way to effectively enrich the background, that is, copy the main body of a layer, change the layer style to positive overlay or soft light overlay on the background, and then reduce the transparency appropriately. This can not only make the picture and background more detailed, but also increase the sense of hierarchy. 4. Adding a formal background is not only decorative, it can also enhance the design sense and formal sense of the picture. For example, the elements in the picture below are very simple, and with a monochrome background, it will look more ordinary. However, if the background is changed to two oblique color blocks, the sense of form of the whole picture will be greatly enhanced immediately, so the background is also very helpful to the form. Color blocks have a strong sense of design and form, so they are often used in the background. There are many such cases. Tip: the elements and typesetting in the picture need not be too limited by the area divided by color blocks. 5. Improve the scene. The visual subject or design requirements of some designs have already defined the design direction of the background. For example, if the subject of the picture is an island, its background will naturally think of the ocean and the sky; If the main body is home appliances or furniture, it is suitable for indoor background; The design requirement is to design a poster of milk powder that reflects natural health, so blue sky and white clouds and green mountains and green grass will be very suitable backgrounds. The main function of these backgrounds in design is to perfect the scene. The sky is a background element with wide applicability, but the choice and design of the sky are also very particular. In fact, although many sky pictures are beautiful, they are not suitable for the background of advertising pictures, such as the following picture. When choosing the sky, we should usually pay attention to the following points:
1. The color of the sky is best to have cold and warm contrast and light and shade contrast;
2. Have a strong perspective to increase the sense of space in the picture;
3. There should not be too many clouds in the sky, otherwise it is easy to appear chaotic and will affect the typesetting of words.
The following sky pictures are good background selection objects. Of course, many times we need to post-process the existing pictures to meet our design needs. 6. Create or strengthen the atmosphere Every design work must have its proper tonality, such as cuteness, romance, joy, warmth, technology, fashion, etc. Then whether these tonalities can be expressed depends on whether the atmosphere of the whole picture is enough, and the area of the background is usually relatively large, so it has a great impact on the atmosphere. ▲ The above pictures are two promotional posters, which need a strong promotional atmosphere, so the designer used a background with bright colors and some details. ▲ In the background of the above picture, a circle of lines composed of dots is used to create an atmosphere of science and technology and the Internet. ▲ Red and blue geometric color blocks of different sizes are used in the background of the above picture to strengthen the fashion atmosphere. After summing up, finally, to sum up, the main functions of background in design are: highlighting the subject, increasing the sense of space, enriching the picture, increasing the sense of form, perfecting the scene, and creating or strengthening the atmosphere. Excellent design can not be separated from excellent background. I hope this article can make everyone realize the importance of background and spend more time on the design of background in the future.
