The meaning of shadow infiltration

Shadow penetration, also known as perspective, refers to the stereoscopic or depth effect of the subject by adjusting the light and angle in photography. Details are as follows:

1, shadow penetration principle: the essence of shadow penetration phenomenon is the transmission and reflection of light. When light shines on the surface of an object, part of the light will be reflected back to the original direction by the surface of the object, and part of the light will be transmitted to the inside of the object and form a shadow behind the object. When these rays enter the human eye, the human brain will interpret the information and perceive the shape and outline of the object.

2. Influencing factors of shadow penetration: Shadow penetration is influenced by many factors, including light intensity, material and color of object surface, observation angle, etc. For example, in a dark environment, the shadow penetration effect of objects will be more obvious; On a smooth surface, the reflection effect of light will be more obvious; When the observation angle changes, the transparency effect of the object will also change.

3. Shadow penetration and visual perception: Shadow penetration is closely related to visual perception. When human eyes observe an object, they can not only perceive its shape and outline, but also its color, texture and other attributes. Penetration interacts with other visual perception factors, and * * * determines people's cognition and understanding of objects.

Application of shadow transmission

1, Photography Art: In photography, the phenomenon of shadow penetration is widely used to create different shades and vivid picture effects. By adjusting the light and angle, the photographer can control the transparency of the picture, thus expressing different themes and emotions. For example, in portrait photography, photographers can use soft light and transmitted light to create a soft and natural atmosphere.

2. Industrial manufacturing: In the field of industrial manufacturing, transparency is also widely used in product quality inspection and manufacturing process. For example, by observing the transmission images of parts, engineers can detect defects such as cracks and bubbles, thus ensuring the quality and safety of products.

3. Environmental monitoring: In environmental monitoring, transmission technology can be used to observe the internal structure and changes of soil, rocks and other substances. For example, by observing the transmission image of soil, scientists can judge the water content and texture of soil, thus effectively monitoring and managing the environment.
