I have been reading on a Kodak website that cold or lack of lubrication can cause cracks in the perforations. I am currently checking every inch of a film that has a lot of these cracks. All my films are well lubricated, but they are stored in an unheated room, and this year has been colder than we have known for a while. i'm wondering if film should be stored in room temperature for a few hours prior to projecting?

Hello Robert, I think that's a good idea. I have the same situation with my films stored in an unheated room. I bring whatever films I intend to screen into room temp for at least an hour or so during these colder months...

The room i use does have heating and goes on with the rest of the house BUT, in the night or through the summer it is a very cool room. I keep meaning to get a thermometer to see what the temperature is. All my films are checked regularly as i do tend to use it most nights and i know every film we have is now guarded with filmguard.

The BFI at their archive in Berkhamsted store their films at minus 5 degrees Celsius, and at 35% relative humidity.
I can assure you that it's cold, I have been in there!

Thanks Joe, in future I will sort out any film I want to watch and keep it in the living room a few hours. I haven't experienced this before. I also discovered that several of the perforation ends had been broken off; does anyone know what could cause this. I always clean the gate area before use, and use a vacuum with a fine nozzle to pick up any debris that might be lurking .

No trouble like that - I maintain a cool environment through the warmer months, but now in the winter no split or broken prefs at all - I have sieves, baking soda (my own invemtion towards VS), and maintain a constant low-humidity airflow throughout - Having many boxed films, my work is cut out for me - Shorty

Thanks.

I have always let my films come up to room temperature before projection.

I remove them from the cans or boxes and let them breath in the room first.

I always give my projectors a good run first too in order to get them up to speed and remove any chance of condensation that may have settled on the metal gates and runner guides.

David, as you may know, my projectors are permanently set up, but despite this, when i go in to start a show, (if i havnt used the projector for a few days or more), i always switch it on to run for a few minuets just to warm everything up, the condensation in the gate is one i have not thought of to be honest so good point [Wink]
After my shows i dont use the cold PVC covers, i pop a medium size towel over the machine and it completely covers it in the same way a pvc cover does. It may not be an advantage but i feel it does do something to keep moisture from cold air out. Being as anal as i am the towels are all washed every couple of weeks with the rest of the dirties [Big Grin] [Wink]

Robert... it is a good habit to get into before a show.

Tom ... Even in the Cinemas every morning we would always warm up our projectors by giving them a good run after first giving them good clean and any maintenance as required.

We did this in all seasons of the year.
