Fantastic info Kenbo, and it was very easy to incorporate it into what I had already built.
My wife had asked for a dedicated area for photos just because she usually makes gifts last minute, but wants to take pics of them before sending them out.
So here is what I made her originally... I had a large 2' square board out in the scrap pile, so I bought some hinges and attached it to the wall with ropes. The blue sheet was our background. Here it is folded down.
I had some old cpvc plumbing attached to the ceiling, so I took it down, preserving the 90 deg fittings in the line. Then I went to the surplus store and bought 2 more 90 deg fittings and some 3/4" pipe brackets. The CPVC is attached to the wall, but can swing around. I then attach the 90 deg fittings to the ends and another piece of pipe to hold them in place in relation to each other.
I then put a line of screws in the wall to hold the paper, just like Kenbo showed (that works GREAT, btw). Throw the sheet over, bring in the lights, and it's picture time!
Not only can the pipes rotate, but they can also move up and down in case she makes a particularly tall intarsia. There's another line of screws higher up to attach the paper up there. So the whole sheet "roof" can be raised higher if needed.
Then, take off the sheet, remove the paper, remove the pipe crossbar, and it all folds up against the wall.
Awesome idea Kenbo, and I'm quite happy it works with what I'd already done instead of having to scrap it (which is NORMALLY what I'd have to do).
