For the last few months, my photo setup has included a roll of printer paper acting as a background. Since adding this, I've saved ages over previous attempts at providing this - to remove all the background for construction shots often involves nothing more than a tweak of the brightness and contrast settings.
When the paper gets dirty, I just unroll a bit. Cut off the old stuff and am ready to go again.
The only problem is that the roll is only 61cm wide and I now have a small layout project in prospect. Worse, that's going to require video and you don't get to do cut-outs on moving images. I need a white background.
So, needing to upgrade to a much wider paper roll in a hurry, I rang around a few places. One said it was delivering on the website, but when I spoke to them, the warehouse is locked down. Another was going to call me back, and didn't.
The winner was Graphic Design Supplies Ltd in Macclesfield. A very helpful chat resulted in a 5ft wide roll being delivered the next day. All I have to do is work out how to support it. Bits of string won't do the job!
