The role of background image

1, the background is used to set off the main body.

Unless you take a close-up, the photo will have a background. Whether it is a black background, a white background or a natural landscape, a basic function of the background is to set off the subject. Solid color background can highlight the main body and set off the theme; In addition to setting off the theme, the natural landscape has other wonderful uses as the background.

2. The background is used to explain the theme.

People pay attention to identity and background when walking in rivers and lakes, and social relations and the endorsement of names play an explanatory role in a person. The subject in the photo also depends on the background to explain something. For example, a tourist photo can be set in Maldives, New Zealand, the United States, Paris and so on. Besides explaining the environment, there are many other contrasts and contrasts.

3. The background is used to balance the subject.

If you take pictures outdoors, there will be many elements in the background that echo the main body and play a balance role. For example, if the characters are near the three-point line, that is, near the golden section line, and other related objects echo the balance on the other side of the background, then the picture tends to be more balanced and perfect. As photographers, we should make good use of these background elements, not only outdoor portraits, but also landscape photos.
