This is an easy removable table-mounted photography backdrop that can be built in roughly five minutes. This came about when it was suggested that my previous ceiling mounted backdrop rig was an eyesore and an impediment to office productivity. To comply with new office-wide zoning standards, I had to create a new rig that was not ceiling mounted, contained within my workspace, and that rose no more than three feet above the surface of my workbench. My own personal guidelines was that it had to attach firmly to my workbench and that it had to be removable. This solution not only meets everyone's needs, but was quick and painless. I am also particularly fond of the pipe clamp supports, which when not in use as supports for the backdrop can double as - you guessed it - pipe clamps.
None of that is probably particularly helpful to you.
We have some photo lights, but they are currently using tungsten bulbs. One of these days I need to figure out a "natural" lighting setup. San Francisco isn't exactly known for sunny days.
