Will it reflect light when taking pictures with a shading cloth as the background?

Effect is very good

Some people even regard it as a darkroom!

Can achieve the darkroom effect.

The shading cloth has a layer of reflective paint and a layer of black cloth (very thin). Used in conjunction with curtains, the shading cloth is outside and opaque. Some are sewn together with the curtains, and some are separated, but they must be sewn on them.

If there is no other light source, it is a darkroom.
