Ok...I've said this before, but I'm really wanting to get more serious about it...I REALLY want to start practicing portraits. At the moment I can't afford any real equipment, so I'm gonna rig some stuff. I'm gonna go looking for some fabric (probably just go with either black or white for now) to use for a backdrop. Here is my question...how big does it need to be? How much fabric do I need? I think I can figure the height alright...but how wide should it be? Thanks in advance!!!
