Shooting in a tiny location can be a nightmare. There’s no place to stage your equipment in any organized fashion, costing you time when hunting for something as simple as the slate or a roll of gaff tape. In addition, it’s almost impossible for the crew to work efficiently without getting in each other’s way — sometimes all non-essential crew need to leave the set to avoid being in the shot!
Tiny locations often result in actors not having a quiet space in which to change clothes or concentrate on their lines. Lastly, the added chaos can often result in needless mistakes and miscommunication.
So make sure you have adequate space for your scene and have each department designate a part of the location as their space. Your AC should have a clean and quiet place to store lenses and upload footage. The lighting department needs space to organize their lights, cables and accessories. The same goes for almost every department. Organization will always pay off dividends when you’re under time pressure.
