I'm sure these will be cleansed as well. It happens, don't get too worked up about it. The mods are just trying to make it better for everyone involved, it's not a personal attack or judgement. You get used to it.

Thank for your fast answer guys.

I am set up in a chamber, I don't have much space to shoot, maybe it's why I get to much light even at 1/250. I will practice and try to set-up in the living room to have more space.

What is the best distance between background, person to shoot, photographer and light ? 7 - 8 feet from each other ?

Your first photo from OP looks just fine...why do you think that you needed to reduce exposure from that?

I presume you are aware of the ability to select lower power levels, from full power?!

Generally you want 5-6' between subject and background, to increase the amount of background blur (less distracting if somewhat blurred) and to permit lighting the backdrop independent from the subject lighting.

Camera-to-subject is in part based upon subject matter (still life close, person's portrait from farther back) and based upon the need for perspective (...i.e., the relationship of the subject to its surroundings). There is no single answer to this question.
