Thank you Phil. Ok, you got me black doesn't exactly reflect but it's the black side of a 5-in-1 reflector (too absorb light) and give an easy black background. I'll post another image done the same way. I could do in studio, but why when using the reflector method is easy. I sometimes pull the translucent part out and use that to soften the light.
