How to label old photos without damaging them

A name on a photo is one of the most useful things you can leave the next generation. Here’s how to add one safely.

The short answer

The safest way to label an old photo is to write on its envelope or sleeve; if you must write on the photo itself, use a soft graphite pencil, pressing lightly, on the back near an edge [1][2]. Lay the photo face down on a clean, hard surface while you write [2].

Never use pens or markers on photos [3][4], and keep sticky notes, tape and glue off them [1].

What should you write on the back of an old photo?

Four things, in this order:

  1. A number, such as P014, so the photo matches your notes.
  2. Who is in it, listed left to right [4], with nicknames.
  3. Where it was taken.
  4. When: a year, a season or a decade.

Not sure? Write a question mark after the guess: “Pine Lake? 1962?” An honest guess is more useful than a blank.

What is the best pen or pencil to write on the back of photos?

A soft graphite pencil, not a pen [1][3].

What if pencil won’t write on the back?

Some photo papers have a slick back that won’t take pencil. Don’t switch to a pen. Put the photo in an envelope or sleeve and write the label on that instead [3][4].

How should you handle old photos?

By the edges, with clean, dry hands. Clean nitrile gloves are good for glossy prints, negatives and slides [1][2]. Keep paper clips and rubber bands away from them [1].

Where should you store labeled photos?

Somewhere cool, dry and dark, in the living part of the home. An inside closet is more stable than an attic, basement or garage [2][5].

  • Keep the temperature below 75°F and the humidity below 65% [5].
  • Use boxes, folders and sleeves that have passed the Photographic Activity Test (PAT) [5][1].
  • Avoid “magnetic” self-stick albums [1][5].
  • An old cardboard shoebox isn’t a good long-term home: the cardboard is acidic [3].

Should you frame the originals?

Frame a copy instead. Display copies and keep the originals in a box; color scans and color copies make good display copies [6]. The same goes for the photos in a family book.

How do you label digital copies?

Give each file a descriptive name and tag the people in it [7]. See what resolution to scan old photos for settings, file names and backups.

What about the story behind the photo?

A label says who and when. The story says why it mattered. Ask the people in the photo, or who knew them, while you can: see the questions to ask about any old photo.
