Photographic lighting and requirements

Photographic lighting and requirements.The so-called use of light refers to the photographer’s selection, utilization and control of the relative relationship between the illuminance, angle, color temperature and the scene. In a broad sense, “use of light” refers to the “use of light” in the early stage of shooting, the “use of light” in post-digital retouching, and the “use of light” in developing prints. The chivalrous “use of light” refers to the photographer’s selection, utilization and control of imaging light in the early stage of shooting. The shooting process is the use of light process. Indoor artificial light is easy to control. The sun is the chief designer who creates natural light and shadow. Outdoor natural light is difficult to control, mainly for selection and utilization. Light is the core element of photography, and the use of light in photography is the art of using light to create contrast.

Controlling the exposure can solve the tone problem, and controlling the color temperature can solve the color tone problem. Direct light has hard light quality, scattered light has soft light quality, and the applicable objects are different. The reflected light of the scene affects the light quality due to the color (white or black, red or blue) and texture (smooth or rough) of the object. The bounce flash has a softer light quality due to increased stroke.

According to the seen or measured light source illuminance or subject brightness, set the exposure combination as appropriate. Secondly, the light color must be considered. The so-called light color is the color of light. Good light color means average success. In addition, the light ratio is different, the resulting shade is different, and the final target is also different. The light ratio of 1:2-1:3 is suitable for high-key photos; the light ratio of 1:4 is suitable for mid-tone photos; the light ratio of 1:5-1:6 is suitable for low-key photos.

Also consider the light position. Light positions such as forward light, side light, back light, top light, and foot light are different. You should adapt to it according to different effects or use it by changing positions. Pay attention to different light types when using light. Pay attention to the unique effects and comprehensive application of main light, auxiliary light, contour light, background light, decorative light, eye light, and effect light.

Consider styling. When using light, it is necessary to consider how to reproduce the shape, color and texture of the scenery, how to use the brightness of light to reproduce the three-dimensional space through two-dimensional plane images; how to create a specific time and environmental atmosphere to express the four-dimensional space. Consider light perception. The imprinting visual effect of light shining on the scene in the photo is called light perception. Photographic works should have light perception, which can be eye-catching and satisfy people’s visual aesthetic needs.
