Display copies of important photographs instead of the originals
If originals are displayed, keep light exposure to a minimum:
- Display photographs for a while and then store them so that none are exposed to light for long periods of time.
- Turn off the lights when no one is in a room. Use lower wattage bulbs.
- Place on walls that get the least amount of sun.
- Close draperies and blinds when out of the room for extended periods of time or when not at home.
- Use ultra-violet filtering glass or acrylic for framed photographs. Use an acid-free mat or a spacer so the front of the photographs does not touch the glass.
- Store photographs and important documents in a cool, dry place where there is minimal fluctuation in temperature and humidity. Avoid attics and basements.
- Store individual photographs and slides in polyester or polypropylene pages or sleeves. Acid-free sleeves or envelopes, which have passed a standardized "photographic activity test" are another option for photographs.
- When purchasing albums or storage boxes, look for those that are acid-free and have passed a "photographic activity test."
- Never put an adhesive on your photographs. Use photo corners, polyester mounting strips or sleeves to mount photographs in albums.
- Store negatives in a separate location from albums and prints. In the event of a disaster, you will have two chances for your photographs to survive.
- Use a soft pencil to label photographs or paper that might come into contact with photographs.
- Handle your photographs and negatives by their edges and with clean hands to avoid soiling the surface.
