Was looking for something that I can use as an effective backdrop, that's light/portable for headshot photography which I'll be doing on location (offices, etc). Here is the link to what I've come across so fa, which basicallly is a 5x7(feet) 2 In 1 Collapsible Backdrop: http://bit.ly/1L8zflZ I have the 5 in 1 collapsible reflectors and when I open it I can see that all the different sides/surfaces (gold, silver, white and black sides) have those random wrinkle lines which are created as result of folding down the collapsible reflector into a disc. So I can not use the black or white sides of my 5 in 1 reflector, as a quick backdrop when I need to improvise quickly on location. 1-Knowing that this product (http://bit.ly/1L8zflZ) is also collapsible, I'd like to know if it has all the wrinkle lines all over its surface or not? Reason why I ask is because, I don't want to have wrinkles on something I'd want to use as backdrop. 2-Has anyone used these collapsible bakcdrops at all for headshot photography? What has your experience been like with them? 3- Any other suggestion for great backdrops, other paper role that's not mobile friendly?
