How to use composition and light and shadow to make photos full of three-dimensional sense

Lead: How to use composition and light and shadow to make photos full of three-dimensional sense? Let me have a look with you.

Visual focus

Visual focusing is nothing more than using shallow depth of field (Shen) to make the theme focus clearly and the background blurred, so that the theme is obviously separated from the background and the photo is more stereoscopic. In addition, the pursuit of shallow depth of field is also one of the reasons that many people pay attention to. In fact, shallow depth of field technology is also the most convenient way to make photos stereoscopic, because as long as there is a large aperture lens or close to the subject (the closest focal length of the lens), the background can be blurred, giving the theme a feeling of jumping out of the background.

Blur the background and highlight the theme

As mentioned above, in addition to blurring the background to create a three-dimensional sense, you can also blur the foreground to create a three-dimensional sense. This is also one of the ways to create a three-dimensional effect by using shallow depth of field, depending on how you present it.

line

The three elements of composition: point, line and surface are the basis of composition. Proper use of lines can enhance the visual impact of photos. Lines can not only increase the artistic conception of photos, but also enhance the three-dimensional sense of photos. Lines can properly guide the audience's line of sight, and through visual guidance, photos will be more layered.

When using line composition, it is suggested that lines point to the theme to be expressed in the picture, so that viewers can directly notice the theme through visual guidance and enhance the impact of the picture.

In addition to the lines and scattered scenes mentioned above, perspective can also produce a three-dimensional sense. For example, using the unique deformation effect of super wide-angle lens (near big and far small), or properly arranging the foreground and middle perspective, can also make the photo more layered. When using a super wide-angle lens to create a strong perspective, if you can get close to the theme, try to get close to the theme and squeeze the' distorted perspective' as much as possible, which can make the photo more perspective.

shadow

Speaking of the final light and shadow, photography, as its name implies, is to capture shadows, and shadows inevitably play a very important role in the picture. Yes, shadow is an element that increases the three-dimensional sense of an object! How are shadows made? Of course it will be produced under the light! When an object is illuminated by light, its color is bright, and then there will be shadows behind the object, which are interlocking.

The light is really changing, and the light is different every second. But in many changes, it can be roughly divided into backlight, top light, side light and smooth surface. Which shadow is easier to create a three-dimensional effect? The answer varies from person to person, because each light has its own three-dimensional sense, depending on how it is operated and what feeling it wants to express.

Look at the three-dimensional effect of light and shadow just mentioned. Now camera technology and computer retouching are very convenient! There is only one sun in the world, and light is always straight. Don't forget the characteristics of light when retouching. In addition, for example, HDR or black cards popular in Gao Fancha scenes are used to control contrast. , but also to follow the laws of nature when using. Appropriate contrast, photos will have a three-dimensional sense, more attractive.
