This is a mini-sized shooting table so simple in its design, its ingenious.
It consists of a flat 39 x 20" sheet of white translucent Plexiglas, and two bead-stop window draw pull-strings. Pull the strings through the holes in the Plexiglas until the desired sweep, or scoop is obtained.
Set it down on any opaque tabletop, and you have a seamless background for a setup of jewelry, models, or other smaller-than-a-breadbox objects.
Set it up on a glass tabletop and position lights above, below, and behind, for dramatic, or high-key lighting with precise control.
