What is a shadowless wall?

Literally, there is no background wall and shadow?

The shadow of the subject was weakened by several lights and disappeared.

It is usually used more in the studio. Just like shadowless lamps used in hospitals, the principle is the same.

Shops who like photography or X-Treasure can make a shadowless wall for photography.

Methods/steps

Making a photo table: You definitely need a table to put the products when taking photos. This is crucial. My practice is to go to the second-hand market to buy an old dining table (like forty or fifty yuan), and then tear down the desktop and leave a shelf. Then put on the china white acrylic board that you bought first, and the photo shooting table is finished, which is very convenient.

Remember: the other side of the acrylic board should be against the wall. The advantage of this is that the acrylic board forms a natural arc, so that the photos we want can be easily done without shadow walls.

Basic shooting: With the shadowless wall for taking pictures, we took pictures. In fact, in this scene, even if there is no light, the background will not be messy, at least it is solid color. That is, to provide clarity and color reproduction of photos. We will use professional photographic flash. I used two 400-watt flashlights. Usually, in the lower part, two lights are placed on the left and right sides of my camera, so that the light can be emitted from the downward direction at a 45-degree angle along the background to complete the shooting of most products. Ha ~ ~ ~ You're done. Let's have one first Wow, that's awesome! ! Very enjoyable! !

Key points of making shadowless wall: This is very important. If it is not done well, there will be traces in the background of the photos taken.

In fact, tables, windowsills and floors are still life shooting platforms, but in order to better display products, a special shooting platform is needed, especially for shooting luminous and reflective objects such as glass, ceramics and crystals. Personally, I think the best materials for still life table are iron frame and white acrylic board. Using acrylic as the background can ensure that the picture is wrinkle-free, but also has certain support, so you can put and drag products on it at will. As soon as the background plate is made into a big bend, as shown in the figure:

Lighting arrangement skills:

Photography is painting with light. Without light, there is no shadow. Because the position, angle and characteristics of light determine the effect of photos. The same product, different light will have different effects. As far as online stores are concerned, two flashlights are enough. When you meet some special products, you need to shoot artistic sense, so it is necessary to have one or two more lights.

With the still life platform, the next thing to do is the arrangement of lights, which is a bit annoying in appearance. Because the stationary stage can't move, when the product is placed on it, if the angle is wrong, you can only find the best shooting angle by moving the camera, so the illumination angle will also change. In order to make cameras, products and lights reach a height of one to one, all lights must be "alive" and can be moved at will.

In general product photography, two lights are enough, that is, two lights are placed on the left and right sides of the camera to illuminate from top to bottom. However, if you want to make the background white, or photograph the unique shape and outline of the product, you need to add two more lights, as shown in the following figure >>.

Tips for taking photos:

Although photography is an art, for online merchants, photography is a kind of record-through digital imaging technology, the most basic physical characteristics of the product itself are truly restored, including materials, shapes, colors, etc., so that people can see the photos as if they had seen the products. Clearly understand the three necessary conditions of the product:

First: Is the light source bright enough? We know that it is difficult to see things clearly at dusk, foggy days, at night, in the room of the underworld and other places. Taking pictures is the same as seeing things. If the light is not enough, the photos are not clear, the colors are distorted, and the picture is rough and dry. From a professional point of view, the color temperature is around 5500K (the sunshine at noon on a sunny day). Only such a color temperature condition can ensure the true color reproduction.

Second: correct focusing is a problem that many people don't understand and ignore. Photography looks simple, but it is not aiming the camera at an object. There are many factors that directly affect the quality of photos. If you can't focus accurately, the photo must be burnt. [Focus tip: Hold the camera on the subject, first press the shutter of 1/2, and then the camera will focus on the subject. When we saw the green indicator light flashing from the lens, it proved that the focus was accurate. We can continue to press the shutter at this time. When pressing the shutter, be sure to keep your hands and camera still]

Third: keep the camera stable? In most cases, we mainly hold the camera. For beginners of photography, it is difficult to hold the camera with both hands. In the process of shooting, once the camera shakes, the photos taken will be "out of sight", the product will become blurred, and in severe cases, obvious shaking marks can be seen. In order to take high-definition photos, tripod is an indispensable tool, and friends with good conditions can be equipped with cable release and shutter remote control.
