The question was asked recently for negatives, and I think I know that slides behave differently.

For the time being, I have had some of my slides in Panodia or Herma sheets, but most are still in the boxes the sheet film came in, individually protected by the transparent sleeves supplied by the processing laboratory. I do not fully trust the Panodia or Herma sheets. They smell plastic and when you have them piled up, it's a LOT of plastic and thus a lot of possible contamination.

In the other hand, I do not trust the cardboard boxes either. Although after ten or fifteen years I have seen no sign of colour degradation on the edges of the slides (all Fujichrome), the boxes are probably not designed for long archival storage. If they are trustworthy, that would be good news for I like that form of storage.

And what about the room and cupboard (I use metal drawers), the temperature and humidity? Does it matter much? Would the hassle of freezing film be worthwile?

Would you share your experiences?
