If I don't have the backdrop at full length, I don't show the floor in my shots. I typically do head/shoulder shots or waist up shots. If I am shooting full body, or using chair or whatever for props, I pull backdrop all the way out. The studio is also used as a classroom, and has not really been actively used as a studio in many years, until I got there, lol, so the flooring is ugly and mismatched tile/wood crap. They did have nice wood panel type of flooring right in front of the backdrop...extending out about 15 feet or so, so I'm guessing they used that. I don't..it looks tacky. The gray muslin and white seamless we have both extend out 50' so there is plenty to pull and spread out to cover all the flooring in the shot.
