By the way, photographic lights have black and silver lampshades. What is the difference?

The color outside has little effect, and the reflective surface inside directly affects the light quality.

But now it is mostly black, because in the studio, we try to avoid the reflection of light by reflective objects, which will affect the lighting effect.

You'd better choose the black one when choosing.

==================================

The reflection of stainless steel will definitely affect the lighting. Unless you only use inverted triangle light, don't be so sure that the influence is negligible.
