Precautions for photography 52- What are the effects of light in different directions on the subject?
Zheng Guang
Positive light usually comes from behind the photographer, that is, in front of the subject. Its characteristic is to "flatten" the photographed object, because it shines evenly on the surface of the object, without layering and three-dimensional sense, but the photographed object shines evenly and the details are clearly visible.
Side lamp
This is more light for portrait photography. When we need to reflect the three-dimensional sense of the subject, the best way is to use side light as part of the light. Side lighting can enhance the details of the outline and increase the three-dimensional sense of the subject by creating shadows and highlights. In addition to portrait photography, still life photography, architecture and landscape photography also rely on sidelights.
Have a bad impression
As the name implies, contrary to positive light, the light source comes from the front of the photographer or the back of the subject. Black light only provides little light to the subject, so it can be said that the subject is separated from Beijing, creating a three-dimensional sense of the picture. People's common silhouette is shot in reverse light, which will cause the subject's front face to be unclear and the outline to be very three-dimensional and clear. If you want to get the effect that the front of the subject is visible and the outline is clear, you can fill the front of the subject with light, that is, combine the positive light with the negative light.
