When I arrived at work this afternoon, I noticed things didn't feel quite right in the booth. Outdoors, the temperature went from 30 degrees and clear to 60 degrees and rainy in a matter of 48 hours or so. Indoors, the humidity was so high in my booth that I could feel it when I walked in the door. I've never dealt with anything like this. The platters felt sticky, the film felt sticky, and I KNEW I was in for it. I cleaned VERY thoroughly, yet several prints began shedding so profusely that the build-up in the gate was causing my picture to go out of focus. I literally had to stop Lord of the Rings mid way through to clean the gate. Yes, it was BAD, BAD form...but what choice did I have? I opened the booth window, apologized to the patrons, and explained to them what I was doing. Luckily, we had no complaints. What do I do? I don't even know where to start. They aren't going to buy me a dehumidifier. They aren't going to buy me a film cleaning unit. The fact is, they aren't going to buy me anything. So without any extra equipment, is there anything I can do to control this? I would appreciate any suggestions...

Brad's suggestion of using the air conditioner (which condenses moisture from the air, acting like a dehumidifier), and treating the prints will help. Putting a layer of FilmGuard or hard wax (e.g., Carnauba) on the film-contacting rails in the gate will help handle film whose emulsion is softened by excess moisture. Heating cold/damp air will reduce the relative humidity, so turning up the heat or using portable heaters would help dry things out too. If it is damp and wet outside, do NOT open the windows.------------------ John P.

In the Puget Sound area of Washington State, we are practically in a rain forest. All it does is rain. We do not shut off the heat in the theaters when we leave. We maintain an unoccupied night temperature of 58 to 60 degrees year round. Under these circumstances, I never recalled having any serious humidity problems in the booth ot theater.
