How to shoot and modify crystals (sculpture, ornaments, pendants, etc. ) On a black background?

A black flannel, a white flannel and a tripod.

Just find a bigger whiteboard as a reflector, and the KT board used for advertising is very good.

The shooting angle is macro, because the object distance is different, the effect is very different There is no question about the appropriate distance here, but I want to make it clear that these different effects should be used for different purposes.

Shooting crystals is a very interesting artistic creation. Because crystals have different modeling effects for different lighting modes. Photographers can sketch the outline of the crystal with lights at will, and they can skillfully use the reflection of the crystal to reveal its glittering and translucent essence. Photographers can use white edge light to outline the shape of crystals in front of a black background; You can also achieve the same goal in the opposite way in front of a white background. What I want to introduce now is the method of shooting crystals in front of a black background. Commonly used lights for shooting crystals: backlight, bottom light and top light. The most common mistake in shooting crystal is to directly illuminate the subject with light from the front. If the lamp is used in this way, there will be dazzling reflection on the crystal, like a mirror. The crystal sometimes reflects the image of the lamp as it is, which makes the picture very ugly. Therefore, no matter shooting any reflective object, don't use direct light! In other words, never shine light directly on the crystal surface from the front. So, what kind of lighting should be used to shoot crystals? There are about three kinds: 1, backlight; 2, bottom lamp, 3, lamp. For example, how to shoot a crystal? First of all, the outline of the crystal should be shot before the white background, that is to say, several white highlights should be drawn on the main edge of the crystal. First, put a beneficial lamp on the crystal, and add a soft light cover in front of the lamp. If the light source area is too large, it will affect the darkness of the background. You can cover the light source with black paper, or add a baffle behind the lamp. At this time, a white highlight will appear at the bottom of the crystal. Then, put a white paper higher than the crystal on both sides of the crystal, and a white highlight will appear around the crystal. With the prominent outline, the crystal shape is exposed in front of the white background, but this is not enough. In order to explain the crystal texture, you need to add a decorative highlight to the crystal. If you take a close-up, the digital camera is very close to the cup. Be careful not to let the camera block the light.
