How to use up photography modeling?

Photography is actually painting with light. So how to draw light? This involves the relationship between light and objects.

1. Representing the shape of an object: People know the concept of independent shape of various objects mainly by observing their contours. The formation of the object contour depends on the reflection of light and the color contrast of the object. When light shines on an object, there is a difference between light and shade. The reflection of light by an object makes it a luminous body, thus showing its position, size, shape and relationship with surrounding objects. Moreover, the absorption and reflection of light by an object shows the color of the object, and the lightness of the color forms the hue of the object. Objects with different colors together play the role of contrast and mutual foil, thus clearly showing the outline of the object. Therefore, in photography, we should not only choose the illumination angle of the light source that can fully express the outline of the subject, but also choose the background and foreground that can highlight the subject from the contrast of objects with different colors.

2. Describe the expression of the object: Light can also illuminate the details of the object, depict the details of the object, and depict the charm. This has played a vivid role in photographic modeling. Focus of light, direct reflection, illumination angle, position of object, etc. It will affect the contrast between light and dark on the surface of the object, and affect its detail description and expression.

3. Distinguish the position of the object: Like the human eye, the camera has a large image of the object near it and a small image of the object far away from it; Objects near it can be clearly imaged, and objects far away from it can't see the details, so the imaging clarity is poor. This imaging principle of "near big, far small and near Qingyuan paste" forms a close shot, a middle shot and a long shot in photographic modeling, which is the result of distinguishing the position of objects by light.

4. Enhance the sense of space: the light enables people to distinguish the position of the object, and the formation of the near, middle and distant views shows the sense of depth of the photo, that is, the sense of space. Taking photos of mountains and rivers on sunny days, using backlight to outline distant mountains, so that far, middle and near scenery can be distinguished, and the perspective of the atmosphere gives people a strong sense of space; If you shoot along the light, it is difficult to distinguish the scene, the light and shade are uniform, the contrast is very small, and it is difficult to show a sense of space.

5. Render the scene atmosphere: morning fog, rainy day, flying snow, etc. The scene is different and the atmosphere is different. The display of the atmosphere of this scene depends entirely on light. In photography modeling, we use light to render the atmosphere. In general, by choosing the shooting angle, it is easy to show a strong scene atmosphere under backlight. Colleagues should pay attention to make full use of natural light as far as possible, and don't add artificial light casually, that is, don't always flash.

6. Express the texture of an object: Different textures of an object reflect light differently. Conversely, the different reflection of light by an object just shows the different textures of this object. Objects that reflect specular light must have a smooth surface; The surface of the object that reflects scattered light must be rough. The weight, hardness, brittleness and transparency of an object can all reflect its texture. In photography, we use light to express different textures of different objects. If the thinness of silk is reflected, it can only be reflected in the backlight, and it is difficult to show its thinness in the smooth light. To express the texture of an object, the light should not be too strong, which will weaken the texture. The wrinkles on the old man's face can only be seen in sideways photos. If you use smooth light, wrinkles will be smoothed out. The skin of children and girls is smooth and delicate, and its characteristics can only be shown by smooth light. If side light or backlight is used, wrinkles will appear on girls' faces.

The use of light in photography modeling is a comprehensive factor, which needs repeated comparative analysis and selection of shooting angle to achieve the goal.
