What are the precautions when shooting products?

In commercial photography, transparent objects such as tea sets, wine utensils and chemical utensils are common and difficult to shoot. When shooting transparent objects, it is not difficult to highlight the transparency of the objects. No matter whether the background is deep or shallow, it will always pass through. However, for the performance of the brightness of transparent objects, it is necessary to use reflection to produce strong "highlight" reflection; The shape of transparent objects uses the refraction of light to achieve the desired effect. Lighting is the key to shooting metal objects, and how to deal with the reflection of metal surface during lighting largely determines the success of shooting. Dull metal objects, such as cast iron, cast aluminum, sandblasting or oxidized surfaces, are easier to illuminate. The main lamp can be directly illuminated by spotlight, and the auxiliary lamp can be illuminated by soft light. Spotlight can produce a certain high light spot, and the soft light softens the shadow. Semi-bright objects, such as bronze and tin, need to be illuminated by reflectors or large-area scattering screens. Low-power spotlight illuminates the main body with a small proportion of direct light, producing an indispensable high light spot representing the metal surface. The most difficult thing to distribute light among metal objects is the object with bright surface. The principle of illuminating this kind of object is to make all the visible bright surfaces of the object reflect the image of the illuminated white mirror or scattering screen.

The most important thing to shoot leather products is to deal with the expression of texture and the composition of objects. In the photography of leather products, scattered light is the main lighting source, and children's direct light is rarely used as auxiliary light. This small part of the direct light will reflect the light in the proper place of the main body, enhancing the texture and outline. When you shoot jewelry, you should first put it away. Jewelry is usually too small to put away easily. General gold and silver jewelry with soft light; For faceted gemstones, direct light is used to distribute the light. The main purpose of photographing food is to show the color, smell and taste of food well, thus arousing people's appetite. Direct strong light is rarely used in the light distribution of food, and directional soft light is generally used, which has the best texture for food.
