广告摄影技巧（Advertising photography skills）Light absorbing, reflecting and transparent objectsIf the object is classified according to the nature of the light, then all objects can be divided into three broad categories, which are light absorbing objects, reflecting objects and transparent objects. In advertising photography, controlling the shooting skills of these three types of objects is the most basic and important.1. light absorbing objectsLight absorbing objects are the most common objects, such as wood products, textiles, fiber products, and most plastic products, all of which are light absorbing objects. The maximum absorption characteristics of light objects is formed completely shades, in the light, high light bright show light color; bright section shows the influence of color and light color of the object itself on its borders; part of light and shadow, surface texture and texture can best display the object is what shows almost no shadow.Advertising photography, the light absorbing object of lighting more flexible. A surface object, such as a coarse ceramic product, that is usually illuminated by a side light to show its surface texture. The smooth surface of the object, such as plastics and paint on the surface of the object, generally shiny, reflective a directional light, so is suitable for large area light source for lighting, lighting, light source should pay attention to the shape, because of the high light part of such objects can be out of shape of light reaction.2. reflective objectsReflective objects are important silverware, electroplating products and enamel products, etc., and its biggest feature is a strong reflection of the light, it generally does not show a soft light and shade transition phenomenon.Light reflective objects generally taken through a large area of light scattering. The 5 is a good grasp of basic lighting light source shape and lighting position, high light reflective objects will be like a mirror reflects the light of the shape. Due to lack of reflective objects are easy to big shades can be changed, so, some gray or dark reflective plate or a light absorbing plate placed on the object side, let the object reflected these color, in order to increase the thick sense of the object, said the consequences of improvement.The reflective object shape and volume of special complex, when we need to use complex lighting methods, the most commonly used is the outflanks lighting method. Outflanks method lighting means in addition to the camera lens aperture, with a light shed will be object surrounded, and then outside the shed bright light. The light shed light to outflank law can be made of white or white fabric, with a transparent support, such as organic glass rod or nylon rope to be fixed. Arrangements with the method of lighting light shed outflanks design is diverse, but one should understand, grasp the reflector like a mirror without reservation all reflected around the back light shed weakness, will be taken in the display object.3. transparent objectsTransparent objects refer to a variety of glass products and some plastic containers, etc. the most important feature of transparent objects is that they allow light to penetrate through its interior.Shooting a transparent object, said transparent object is not difficult, regardless of background is deep is shallow, it will go through; however, the said transparent object light sense, to use reflection, so that the occurrence of strong high light reflection, refraction of transparent object shape by light to reach the expected consequences. If the Convention for transparent objects such as lighting, with a 45 degree side lighting, shooting the consequences is not good, at this time, most of the light will pass through the object, only a small part is reflected, no matter what motor 3 background and color, transparent objects only vaguely visible. The best way to represent a transparent object is to photograph a man in a bright background, with objects appearing in black lines or, before a dark background, objects appear in light colored lines.The bright background of black lines is an important application of light illuminate the object background light refraction effect. Transparent objects put enough on a light background in front of the distance, a spotlight with the background of circular light illumination, beam cannot shine to the object, then the background reflected light through the transparent objects in the object edge black lines formed by refraction,The width of a line is proportional to the thickness of a transparent object. Changing the intensity and diameter of the beam can lead to different consequences. The stronger the beam, the smaller the diameter, the stronger the contrast. The contrast of the picture is only determined by the intensity and diameter of the spotlight, which is very beneficial to the control of the shooting.Dark backgr
