There are many types of textiles, with different weaves and textures. Whether it is to express a piece of fabric independently or to make it into a fashion to wear on a model, customers are very demanding on the performance of the texture of the fabric, especially as a postal sample, the pattern and color of the textile cannot be any deviation, otherwise the buyer will Right to return.

cotton wool

Cotton and wool textiles can be divided into flat, fine and rough due to different raw materials and weaving methods, but they are basically absorbing subjects. There is no flare in the lighting. Therefore, the lighting focus is on expressing texture and color texture.

The degree of light diffusion of cotton and wool fabrics determines the texture performance of the fabrics. If the fabric is squared, with a horizontal mid-ground light level and a vertical rear side light between floodlights, the fabric will appear rather rough. When the image is enlarged, the interweaving texture is clear, and the velvet or fur has a backlit outline, but the projection is also thick. Therefore, the tone is blunt. If the main light and the diffuser are softened, it will not only reduce the contrast, but also shorten the projection and reduce exaggerated components.

For fine cloth, the light position of the main light can be increased, the lightness should be softened appropriately, and the texture performance will be smooth and detailed.

The printed canvas should mainly express the color, and sometimes it is not necessary to emphasize the texture too much. Because there are many varieties of floral fabrics, some are elegant and some are bright. The chromatic contrast can sometimes be drawn so much that when lighting and exposing, it may be difficult to balance the color and texture. For example, a large area of ​​white and gray color fabrics have effective dark black patterns. After exposure, the white and gray parts of the image have good color textures, while the texture of the dark black parts may not be very clear.

silk damask

These two types of fabrics have to show both beautiful patterns and soft, charming, shiny textures. The light source of silk and brocade fabrics should be soft and diffuse, and should not be too strong. Fog lamps and diffusers should be lighted from a slightly higher position in front of the fabric. If these two types of fabrics are worn on the model, the front lighting can better show the texture. If the above-mentioned lighting cannot show the lustre of silk brocade under the light, it is necessary to set up auxiliary light to create it. When the model wears it, the fabric will wrinkle with the body. If you are only photographing the fabric, it is recommended not to lay them flat, but to show undulations. These folds and undulations help the fill light to create the right amount of area, with the right amount of reflected light, giving it a glossy character. The so-called appropriate area and appropriate brightness means that this part of the reflective cloth should be too large and bright, otherwise it will be too dazzling, cluttered and submerged in texture performance. The fill light should be biased to the side. The adjustment of the auxiliary light must be observed from the angle of the camera lens until the distribution and direction of the bright part are satisfactory.

Yarn Nylon

Most of all kinds of yarn and nylon textiles are translucent. Yarn and some nylon textiles are soft and airy. Nylon fabrics are slightly stiffer and stiffer than the former.

The front light should be soft and diffuse to show the texture of the fabric, and the backlight should also be soft and diffuse and slightly brighter than the front light. In order to transmit the texture and texture of the textile. If there are patterns printed on the textile, the backlight brightness should be properly controlled. Too strong will make the pattern gray or white and reduce the contrast; if it is too dark, it will not show translucency. When photographing white or light-colored yarn, it is best to fold the surface of the yarn, so that the light and dark contrast formed by the different thickness of the yarn after backlighting can enhance the translucency. The background cloth should be too dark, otherwise it will produce a heavy and depressing feeling.

The texture of textiles is soft and fine, and it is not easy to observe clearly from the focusing screen. To determine light level and texture, look carefully from the axis of the lens with your eyes. Focus must be absolutely accurate and use a magnifying glass to see if the image of the textile on the focus glass is clear.

The above are mainly the principles of lighting that are mainly textiles. If these textiles are made into fashion and worn on models, it is necessary to emphasize the fashion style and express the texture of the fabric. The undulating lines of the model's body will create some noticeable shadows after the key light is illuminated. The texture performance of these dark areas will be very poor, and they need to be filled with light, which should be softer and weaker than the key light.

Points to pay attention to

Different textiles will have rough, soft, light and heavy textures. Generally speaking, the main light mainly expresses the texture of the textile, and the auxiliary light is mostly used to emphasize the dark part and the soft and thin head.

For rough, thick and clear-textured textiles, the main light can be slightly harder, the light level should be low and sideways, and the auxiliary light should be soft and diffuse.

The key light of bright fabrics must be soft, diffuse and weak. The reflection at the folds of the fabric is an indispensable factor to enhance the texture. If the main light cannot be expressed, add auxiliary light to shape it, but the reflective area should not be large, and it should be smooth. At this time, it should be noted that although the reflective light is high in brightness, it cannot cause the flare to lose its texture.

The translucency of gauze textiles is mainly expressed by backlighting. The lightness should be soft and scattered, not only to reflect the patterns and colors, but also to show lightness and softness. When the front fill light is required, the reflected light can generally achieve the effect.
