Sometimes the best way to hide something is to focus attention on it. I have a hole in my backdrop that leads into the next room (eventually). I decided to build a building around the hole.
The lighting looks great in the dark, but I couldn't get a good picture because the camera compensates and overexposes. The lighting in not anywhere near as bright as it look in the "night" picture.
Of course I still need to ballast the track and do some scenery around the loading docks.
A would be interested in seeing how others on the forum have dealt with a hole through the backdrop.
