Black or crimson flannel can be used as a photographic background for diamonds, zircon and rhinestones to eliminate all reflections. The lighting angle should be found according to the polished surface of diamonds, zircon and rhinestones, so as to reflect the glittering and translucent appearance of diamonds, zircon and rhinestones. Of course, the number of lighting lamps should also be appropriately increased according to the actual situation. The main light source should reflect the lighting effect of diamonds, zircon and rhinestones, and it is best to use the macro camera lens to show diamonds, zircon and rhinestones.

Because each lens has the closest focal length, this is a very important design and manufacturing index of the lens, which is engraved on the lens and may not be noticed by ordinary people. When shooting, if you are closer to the subject than the nearest focal length, you cannot image. Therefore, the ordinary lens should not be too close to the subject, in other words, the imaging of the ordinary lens should not be too large. You can buy a macro lens, or you can use a reverse ring, a close-up ring, etc.

Note: How does an ordinary lens instantly become a super macro lens? The lens is connected to the fuselage with a reverse connection ring, sometimes it can be a few centimeters away from the subject, or even "stuck" to the subject, and the surface lines of the subject can be clearly seen from the viewfinder. With the reverse ring installed, autofocus can't be used. You have to move the body back and forth to focus.
