Why is there such a big difference between the appraisal certificate and the jade bracelet?

There is a great difference between the picture on the appraisal certificate and the real jade bracelet for the following reasons: 1. Shooting conditions and equipment: The pictures in the appraisal book may be shot by professional photographers with special photographic equipment under certain conditions to show the characteristics and details of the jade bracelet to the maximum extent. However, these situations may not fully conform to the actual situation in daily life, which leads to a certain sense of gap when consumers see the real thing. 2. Image processing: Although the picture of the appraisal book should reflect the real situation of the jade bracelet as much as possible, sometimes in order to better show some features or solve problems in shooting, some post-processing may be carried out, such as adjusting brightness and contrast, cutting or adding comments. These processes may lead to differences between objects and pictures. 3. Angle and light: The shooting angle and light conditions will greatly affect the appearance of the jade bracelet. The picture of the appraisal book may be shot in the best light and angle, and consumers may not be able to completely restore this state when they see the real thing, thus creating a sense of difference. 4. Personal aesthetics and preferences: Everyone has their own aesthetics and preferences, so for the same jade bracelet, some people may think that the object is better than the picture, while others may be the opposite. In short, the pictures on the appraisal book are for reference only, so it is best to fully understand and negotiate with the merchants before buying.
