Care and Handling
Care and handling of photographic materials should not be overlooked. Photographic prints and negatives need to be cared for appropriately if they’re going to last. The best protection is to house them in photo-safe materials (plastic or paper envelopes, sleeves and boxes) and then store them in a cool, dark, and dry environment.

Examples of different types of enclosures for photographic negatives. The sleeves in the front are archival enclosures as the plastic was not manufactured using damaging chemicals known as PVCs. Dave Brown photo.

Archival Enclosures
Storage enclosures come in many different types, sizes and shapes. Boxes, albums, sleeves and envelopes can all be used to protect photos and negatives. Enclosures made of “acid-free” paper and stable plastics like polypropylene or polyethylene are ideal for storage. Avoid using acidic cardboard, vinyl enclosures and “sticky-back” photo albums that can harm or ruin photos and negatives. Not all materials are preservation quality even if they’re sold as “acid-free”. Look for archival enclosures that do not contain lignin or additives and are pH neutral and chemically inert. While archival storage materials may cost more, they’re more reliable.
Storage Conditions
Choosing the right storage location in your home is like adding another layer of protection. It is convenient to store photos in basements or attics, but basements are often damp and prone to flooding, while attics tend to be too hot and dry. Once your photographs are in the correct enclosures, the best place to store them in your home is in the darkness of a main-floor closet where the indoor climate is more stable.
