Intermediate skills in Digital Photography - light for photography Author: unknown source: PConline release date: 2005-04-13 hits: 2184 Light is the most important component of photography, and the processing of light is often more important than other important elements. Light does not only make the target imaged on the CCD of the camera, but the good photographer can also use different kinds of light to express different artistic conception. There are three elements in any kind of light, that is, intensity, direction, and hue. Intensity of light Intensity describes the intensity of light, and the intensity of light emitted by various light sources has a certain intensity. Bright light is usually caused by direct illumination of light emitted by a strong light source, and, of course, a weak light beam can form a very strong beam through gathering. Strong and direct light will cause obvious shadow, and clearly showing the outline of the object, so it is commonly used to outline the contours of objects; light also can increase the contrast of the main subject is to emphasize between surface texture, different color or hue contrast. The weak light can weaken the contrast of the subject and make the surface appear smooth and detailed. For the illumination of photography, strong light sources are often used as main light and are the main source of illumination. The weak light source, which is used as an auxiliary light, can weaken the intense shadows caused by the main light without projecting unwanted shadows. But the light is too strong, often do not receive good results, because the shadow under strong light will be exaggerated, the effect of light and shade is not natural.
