iF your items are massive a white sheet pinned to the corner of the room work witha table under the sheet and then load it into a photo or art program and play with the contrast and britness almost hides the white sheet

. But i just use a black sheet for other items white and light items no messing with contrast though still looks ok.
I buy just king sized white and black sheets from asda mak sure there ironed well other wise it looks like a sheet if its ironed well it looks ok lol.
Thanks again SRJ.
