Subject: storing negatives - cool or cold?

Question
I know negatives & photos are best stored below 68 degrees; is there a temperature limit to how COLD they can safely be stored?

We want to store our "snapshot" negatives outside of the house (we have friends who lost all family photos & negatives in a house fire).  In our area in northern Minnesota it can reach -30 degrees in winter and 90+ degrees in summer.  As I see it, our obvious options are:  
1) sealed tub in unheated, uninsulated garage (cold in winter & hot in summer - poor solution, right?)  
2) sealed tub in unheated, INSULATED shed (cold in winter but stays cool in summer - better?)
3) I could build a small insulated box just big enough for the tub, but wired with a light bulb to provide warmth in winter. (possibly OK but would take experimenting to determine bulb size vs. temperature?)

One last idea we've tossed around is to store them at a relative's home (an hour or more away) but I contend that they are just as likely to be destroyed in a fire there, plus there's the obvious downside of not having them here on hand when we need to get to the negatives.  Your thoughts, please!  

Answer
Dwest,

I think you missed the most obvious and safest.  Rent a large safety deposit box at a bank.  You can get them for under $100 a year (you may even get one free with your account).  You do need some air circulating, having boxes that are heavily sealed are OK if you store the items during a dry period, but if it's humid when you put the negatives in the box, you could get some moisture locked in. With a bank box, the room is always kept a constant temperature and humidity.

If you have thousands, organize the negatives, get rid of the junk. I don't know the number of negs you have.

Another thought, that will require a one time investment of about $300 and lots of time is a negative scanner.  You can scan all the precious negs and burn them to a CD or leave them on your computer hard drive.  You can get about 500 negs on a CD - depending on the scan size.  You then can put them CDs in a safety deposit box with you other valuables.

Hope this helps..


Mark
