Judging the value of jade quality, there are four main aspects, water (gloss) / color / carving / transparency, a good jade photo should show these four aspects.
There is such a saying in the industry that "the jade is not under the lamp", mainly because the color of the jade is different under different light, so you want to accurately understand the color of the jade, the natural light is preferred, and the photo is even more so!
The performance of the gloss, first determine the direction of the light and the position of the camera, so that the reflective surface of the jade appears in the most appropriate position, different emerald species will have different luster, so it is necessary to use the smooth or side light to see the jade water .
The color performance, the camera should have the manual white balance function, because it is natural light shooting, so the color temperature changes may change at any time, if necessary, do a white balance setting for each shot.
The performance of the engraver, the good engraving is mainly in the details, so I think that the camera should use the close-up function to facilitate the close-up performance of the engraver.
The performance of light transmission, the transparency of jade is the most fascinating, taking a good light, the life of jade can be perfectly interpreted, so the light is very important, but it is also the most difficult to master, the first to be exposed Knowledge has a deeper understanding, more than one block and one block has an effect on the final photo effect. The choice of the second angle, many jadeites have fluorescence under the light, it is very beautiful, but want to be on the photo, then You need to know the angle of the camera and the jade accurately. The third light-transmitting photo must be backlit, and it is important to prevent light from entering the lens. Otherwise, the photo will be very gray and affect the performance of the jade.
