My thoughts...
If you run your camera on any form of auto, gain, level, iris, focus, it is very hard for the camera to give you good images when against a white backdrop. Lighting is very difficult to manage. you may get washed out scenes or the details are too dark to make out. Focus is hard, manual or auto, when you have to adjust all the other elements of the camera because of all the action and constant scene change due to your talent. If your talent are dressed in white, it may become difficult to see their details against a white set.
Your best bet is a more neutral or natural color backdrop.
How big a "set" are you trying to dress? Could a new disposable painters tarp (tan paper on a plastic backing from Home Depot/Lowes) or maybe a cheap bed sheet (Target, Kmart) be big enough?
Life is not a guided tour nor a destination.
It is a journey. Take the time to enjoy your family, friends and surroundings.
Build memories. Share experiences. Travel at sight speed not light speed. (C)
