If you know what you buy and how to use it, the folding background is a big help. As in the product description, it is even exciting, but not wrinkle free - is indeed a folding background and where folded crease arise ;-) clamping together makes it also relatively quickly, depending on how often you have already done. If the first and second attempt something stubborn in size and you can hurt a little, but if you get the technique, it's quick, frust- and painless. As some have already written: Youtube help. Even if you have the background in the photo sharply, it is better to have a little wrinkle structure than with a field use a very troubled background without this part. I'll be there in any case not iron. Of course you can by light, aperture, distance and Photoshop soften the wrinkles or disappear. Who do not want any wrinkles, should get better paper backgrounds when enough bursts and money is available and if time does not matter during assembly and disassembly.
