What kind of photograph album should I use / How should I store my photographs and/or negatives?

Polyethylene or polypropylene photo sleeves that fit into ring binders offer an easy solution, (“Care of Photographs,” Northeast Document Conservation Center)

If using an album with paper pages, secure photographs to the album page with photo corners. For other storage ideas and additional information, including how to store negatives and slides, see Care of Photographs,, (Northeast Document Conservation Center).


Store the album in a preservation-quality box,, (“Storage Enclosures for Books,” Northeast Document Conservation Center) in good environmental conditions,

What kind of pen should be used for marking/signing photographs?

Permanent ink pens that pass the photographic activity test (PAT) (ISO 18916) can be used on semi-gloss inkjet papers, films, and polyester, polyethylene, and polypropylene photos sleeves and should not fade, bleed, or transfer when used properly. Such pens (Internet keyword search: “film marking pen preservation”) can be purchased from preservation suppliers.


General Care and Handling of Photographs

The information on this page covers photographic prints from all eras of photography and photographic negatives, but not digital image files.

Taking care when handling any collection item is one of the more effective, cost-efficient, and easily achieved preservation measures.

Take proper care when handling photographic materials by:

  • Having clean hands and wearing non-scratching, microfiber or nitrile gloves; having a clean work area
  • Keeping food and drink away
  • Not marking photographs, even on the back side
  • Not using paper clips or other fasteners to mark or organize prints
  • Not using rubber bands, self-adhesive tape, and/or glue on photographic materials

General Guidelines for the Proper Storage of Photographs and Negatives

Good storage is arguably the most important preservation measure for photographic prints and negatives:

  • A relatively dry* (30-40% relative humidity), cool** (room temperature or below), clean, and stable environment (avoid attics, basements, and other locations with high risk of leaks and environmental extremes)
  • Minimal exposure to all kinds of light; no exposure to direct or intense light; use duplicate slides in light projectors
  • Distance from radiators and vents
  • Minimal exposure to industrial (particularly sulfur-containing) atmospheric pollutants
  • Protective enclosures within a box***

* Relative humidity is the single most important factor in preserving most photographic prints.

** For contemporary color photographs and for film negatives, however, temperature is the controlling factor affecting stability. Storage at low temperatures (40°F or below) is recommended. Appropriate enclosures for cold storage are available from various vendors.

*** Suitable protective enclosures for photographic prints and negatives are made of plastic or paper that meet certain specifications:

  • Paper enclosures must be acid-free, lignin-free, and are available in both alkaline buffered (pH 8.5) and unbuffered (neutral, pH 7) stock. Storage materials must pass the ANSI Photographic Activity Test (PAT) which is noted in supplier’s catalogs. Buffered paper enclosures are recommended for brittle prints that have been mounted onto poor quality secondary supports and for deteriorated film-base negatives. Buffered enclosures are not recommended for contemporary color materials. Paper enclosures minimize unnecessary light exposure; are porous; easy to label with pencil; and are relatively inexpensive.
  • Suitable plastic enclosures are made of uncoated polyester film, uncoated cellulose triacetate, polyethylene, and polypropylene. Note: Photographic emulsions may stick to the slick plastic surfaces of these storage materials at high relative humidity (RH). Plastic enclosures must not be used for glass plate, nitrate, or acetate-based negatives.

Prints of historic value should be matted with acid-free rag or museum board for protection. Adhesives should not touch the print. Matting should be done by an experienced framer or under the direction of a conservator.

Store all prints and negatives (whether matted or in paper or plastic enclosures) in acid-free boxes. If possible, keep negatives separate from print materials. Store color transparencies/slides in acid-free cardstock boxes or metal boxes with a baked-on enamel finish or in polypropylene slide pages. For more information about storage of negatives, see Motion Picture Film,

Protect cased photographs (e.g., daguerreotypes, ambrotypes, and tintypes) in acid-free paper envelopes and store flat; keep loose tintypes in polyester sleeves, or, if flaking is present, in paper enclosures.

Storage of family photographs in albums is often desirable and many commercially available albums use archival-quality materials. Avoid albums with colored pages and “magnetic” or “no stick” albums.
