I'm guessing by the result it adds a dark satin-like effect to the photo.
I'm sorry but I could hardly understand what you were saying. I understand you have an accent which I will ignore, but your pronunciation makes it hard to understand what you are saying. To me it almost seems like you are faking it, because the title is 100% without mistakes and in the thread, your spelling sucks. I'm not trying to make fun of you or anything, but it almost seems like your pronunciation and your accent are fake, as proof. The fact that you are from a foreign country and PS is still in english proves that more that you maybe faking it.
TLDR; Your pronunciation makes it hard you. Also, it seems as if you are faking your spelling, your accent and your pronunciation. Try to work out these things out (if you are seriously foreign). .
