As a professional photographer I have seen many backgrounds. Material is practical - as well transportable. With white I do not care whether it reflects a lot because it can thus appear "whiter" and white anyway always brightens. I therefore hope that at "white" really a very light background, or light-white. This product is rather of 20% light gray! it shows only if it lays a sheet of white paper on it. Even the fabric is very thin that it is transparent and if you're behind it are still färbliche things or dresser light through these colors. He knittet also very. The fabric could be better, the price is quite cheap - but for professional use this product has completely umbrauchbar. Unfortunately.
