I have a quick question to throw out there. I'm doing lighting and set design work for a production of My Fair Lady and we are constructing a two story study. The height of the study is forcing us to raise teaser heights and now we aren't going to have enough space to completely fly out a couple backdrops we will be using. We are planning to rig the backdrops so that they shorten themselves as they are flown out. We did do this once in the past, I wasn't involved in it then but it seemed to work alright. I'm just wondering if there is a particular term or expression that refers to rigging a backdrop in this way. Any suggestions on the best way to do it? The way I'm planning is to connect 4-5 lines to the bottom of the drop on the back which run up to pulleys on the batten and then to the ends of the batten. At the ends of the batten the lines go through another pulley that send them to the stage floor where they are anchored. This is rigged when the drop is flown in so that when it is flown out the bottom of the drop is pulled up toward the batten. I believe this is roughly what was done in the past. Any tips or suggestions?
