Denny Manufacturing is the biggest maker of backdrops. Westcott, Photek and many others are also big. 10x20 is the most versatile of the popular sizes because you can do anything from a head shot to full length. But it's the least portable because of its size. The Background in a Bag/PeoplePopper are very portable, but limited to maybe two people. Solid black and white backdrops are available cheap from Adorama but are of very limited use. Those are not colors you would normally shoot a studio portrait against. Much better off with various mottled shades of blue or gray. The late Monte Zucker liked a mottled shade of green and Denny actually makes a greenish backdrop named for him. Muslin is the most popular and portable fabric but canvas is used a lot in the studio especially for scenics. Seamless background paper is cheap if you want solid colors. Definitely go to the Denny web site to get an idea of what's available, then shop cheaper places if you can't afford them.
