The methods used to express the sense of space in photography are as follows

The methods used to express the sense of space in photography are as follows:

1, use prospect

When there are prospects, middle scenes and distant views in the picture, there will be a strong sense of depth. In photography, it is an effective way to express distance, space and depth by introducing the viewer's line of sight into the picture and moving it to the center of the whole picture.

2. Use perspective traction line

Perspective traction line, also known as line perspective, is a technique to express the sense of depth of screen space with lines. People have accumulated relevant experience about linear perspective phenomenon and perspective law: when the distance between the scene and the shooting point is different, the image size is different. The closer to the shooting point, the larger the object image; The farther the distance, the smaller the object image.

Lines regularly arranged by objects, such as parallel lines, tend to converge towards the middle. The farther the distance is, the closer it is, and the last bit disappears into the field of vision.

Step 3 Use size comparison

According to visual experience, large objects seem to be close to us, and small objects seem to be far away from us. Therefore, the size of the object in the picture actually implies its distance from the viewer and its position in space.

Wide-angle lens has the imaging characteristics of "near big and far small", so shooting with it will have a strong sense of depth. The telephoto lens has the imaging characteristics of "compressed perspective", so the sense of space will be weakened when shooting with it.

4. Use overlap and occlusion

The overlapping structure will clearly show that one scene is behind another. When focusing, depth of field control or line perspective cannot be applied for some reason, and overlapping may be the first choice to express the sense of space.

And different occlusion angles have different spatial sense. Generally speaking, if the overlapping scenes are blocked by the head-up state, although there is a certain relationship, the sense of space is still not strong. If the plane is a little higher, so that the picture can be blocked and perspective, then the sense of space will be stronger.

5. Use different light.

The main influence of light on sense of space and depth lies in the level and quality of light. Because the illumination of the front and rear scenes is even when the light is smooth, it is difficult to produce a sense of space.

Under the illumination of side light and backlight, the three-dimensional sense of the shooting scene is improved, so it has a better sense of space and depth. In terms of light quality, generally hard light produces a strong sense of space, while soft light produces a weak sense of space. Side light or backlight is more likely to make the picture appear bright and dark contrast, which is more suitable for expressing the sense of space of the picture.

6, the use of clear and fuzzy contrast

By controlling the focal length and depth of field, different clear or blurred areas can appear in the subject, and the contrast between clear and blurred areas constitutes the sense of depth of the picture. The more obvious the contrast between clear and fuzzy scenery, the stronger the sense of depth.

In addition to using focal length and depth of field to blur the background, fog or haze weather can also be used to blur the scene itself, which can also enhance the sense of space in the picture.

7, the use of color contrast

Visual experience tells us that dark objects look closer, while bright objects look farther. Therefore, when the color tone of the shot scene is too dull and the sense of space is poor, it is advisable to improve the contrast of the color tone of the scene by controlling the filter and exposure, so as to adjust the sense of space of the scene.
