Hot and beautiful shots. Dear friend, if you try all these things, it's great. Black color absorbs all the light and has no reflection on the subject, it is necessary to separate the subject from the background with complementary lights. I usually use three light stands for photography with a black background
for a long time the ceiling was white and that was cool for taking photos. Then they had a play that was happening in the dark so they painted everything black, even the background. That was hell for taking photos of live shows.
I never got to 3. I feel that i never had the time to set it up :)
