Portrait photography, lighting style, design conceptThe design concept of the lighting style of portrait photography mainly revolved around the following aspects:
** 1. Create character characteristics and atmosphere **
1. ** Strengthens personality and temperament **
- For example, splitting the light and dividing the face into two, one side light and one side dark, could create a strong sense of drama. It was suitable for people with strong personalities or temperament, such as artists, musicians, etc., and would also have a strong masculine taste. When using this lighting arrangement, one must pay attention to the change of the lighting arrangement according to the face of the subject. When the head turns, the lighting also needs to follow.
2. ** Adjusts facial appearance **
- The wide light turned the side of the light to the camera, which was suitable for people with thin faces. The thin light turned the darker side to the camera, which made the face look sharper and more three-dimensional. The two lighting methods were the same but in opposite directions.
- The circular lighting allowed the nose to cast some shadows on the cheeks, and the light source had to be slightly higher than the plane of the eyes and the camera by 30 - 40 degrees. If the reflective board was placed too low, the light hitting the nostrils would not be able to create the desired effect.
- Under the Paramount Light, the two sides of the character's nose, from the bottom of the eye to the edge of the cheekbone, would form a bright area, looking like the shape of a butterfly's wings.
- There was an international standard for triangular light. The shadow of the nose was cast diagonally downward toward the corner of the mouth. There was a bright triangular light block on the face in the direction of the shadow of the nose. In actual shooting, a large triangular light and a small triangular light were derived, which had a unique effect on the three-dimensional feeling of the human face.
3. ** Creating a different atmosphere **
- The top light was a special styling effect. The prominent parts such as the forehead, cheekbones, and nose bridge were very bright, while the back light under the brow bone, eye sockets, under the nose, and chin would form a thick shadow. The subject's face was distinct and had a strong three-dimensional outline. In addition to providing the main light, it could also take into account the outline light (such as light) and decorative light (such as eye light). The relative distance between the light source and the person was adjusted according to the shooting intention. The closer the light source was to the subject, the softer the light would be, and vice versa. Under the top light source, by arranging a reflective plate on one side of the subject, the contrast between light and dark could be reduced to ensure that the dark details were reflected.
** 2. Guide the viewer's line of sight and visual attention **
1. ** The importance of the direction of light projection **
- The direction of the light was the most important part of the lighting arrangement. Light from different directions had different modeling meanings, which determined the size of the light receiving surface and the area of the shadow. The contrast of light and dark directly determined the tone and atmosphere of the picture. For example, backlighting, where the light angle was opposite to the shooting angle, was relatively rarely used in portrait photography. The light angle was the same as the shooting angle, which was more common but not suitable for expressing the sense of space and was suitable for showing positive details.
2. ** The influence of the face and gaze direction **
- The direction of a character's face determined how much light the face received. Generally, the face faced the direction of the light source. When the face needed more light, the character could turn the face slightly to the light, and vice versa. At the same time, this would cause a series of changes in the outline, eyes, limbs, and so on, which needed to be adjusted accordingly.
- The eyes of a character were the most important organ to convey emotions. The expression of the eyes could convey the artistic conception and atmosphere of the work. The character's eyes looked at the camera or elsewhere with different meanings. Opening or closing the eyes also described different emotions. The direction of the character's gaze was also a factor that needed to be considered when designing the lighting style.
** 3. Draw lessons from the art of painting **
1. ** The use of light and dark techniques **
- The same problem that photography and painting faced when transforming a three-dimensional world into a two-dimensional world was how to display a three-dimensional visual experience on a flat surface. Light and darkness could hint at volume and space, becoming an effective means of expression. For example, the Renaissance painters 'research results on the changes and expressiveness of light and shade were used by photographers. Caravagio developed the tradition of using light and shade to express volume and space and create a mysterious atmosphere to the extreme. Rembrandt created a wonderful light effect in front of the dark background. The color of the bright part was thick, and the dark part was thin and transparent. This contrast between light and dark could also be used in the design of portrait photography. The dark background and dark-colored clothing could be used as a prerequisite for lighting. This contrast between light and dark made people feel comfortable and pleasant.
