Does the light shine in front of or opposite the camera?

Generally installed on the camera bayonet, consistent with the lens direction. This is the case with the Jin Yan camera lamp I used, and the effect is very good. Unlike photography, which requires artistic effects, it uses sidelights.

The camera can't take pictures in front of the light. First of all, light is more powerful. During shooting, light shines on the lens above the camera, which may cause astigmatism. When the camera takes pictures again, the transparency of the picture is very strong, which may damage the camera, so you must never take pictures in front of it.
