Historic Photos and Old Pictures: The Complete Guide
Old photographs show how our towns, streets and people looked long ago. This guide explains where to find historic photos, how to date them, what copyright rules apply, and how to scan and preserve old family pictures.
What are historic photos?
Historic photos are usually images several decades old that document a past era: city views, street scenes, buildings, portraits, events and picture postcards. The first permanent photographs date from the 1820s and 1830s; from around 1850 glass-plate negatives and albumen prints spread widely.
Around 1900, picture postcards became a mass medium, and many of the finest town views of that time come from postcard publishers. With roll film and small cameras, photography became part of everyday life from the 1920s on.
Where to find historic pictures of towns and cities
Great sources include city and state archives, national libraries, the Library of Congress, Europeana, Wikimedia Commons and the Digital Public Library of America. Many archives offer online databases searchable by place and year.
Local history societies, museums, flea markets and postcard auctions are treasure troves too. On Histo we collect historic photos sorted by place, and every picture comes with its background story.
How to date an old photograph
Look at clothing, hairstyles, vehicles, trams, shop signs and buildings that did not yet exist or had already disappeared. For postcards, postmarks, stamps and the back layout help: divided backs for address and message appeared in most countries between 1902 and 1907.
The material tells a lot as well: daguerreotypes (c. 1839–1860), ambrotypes, tintypes, cartes de visite (from c. 1860), cabinet cards (c. 1870–1910) and gelatin silver prints. Comparing with dated archive images of the same place often narrows the year down.
Copyright and old photos
In the United States, works published before 1931 are in the public domain (as of 2026). Many other countries protect photos until 70 years after the photographer's death. On Histo, automatically added photos are always taken before 1931.
Very old photos by unknown photographers are often in the public domain, but checking each case is still wise. This section is not legal advice.
Scanning and preserving old photos
Scan prints at 600 dpi or more and negatives or slides at 2400 dpi or higher. Save files as TIFF or high-quality JPEG and record place, year and people in the file name or metadata.
Store originals cool, dry and dark in acid-free sleeves or archival boxes. Avoid tape, rubber bands and ballpoint pens on the back; label only with a soft pencil.

Frequently asked questions about historic photos
When is a photo considered historic?
There is no fixed rule. Photos are usually called historic when they are at least 50 years old or show a clearly bygone era.
Can I use old photos I find online?
Only if they are in the public domain or carry a suitable licence. Look for labels such as Public Domain, No known restrictions or Creative Commons, and credit the source.
Are photos taken before 1931 copyright free?
In the US, works published before 1931 are public domain. Elsewhere protection often depends on the photographer's death year, but very old photos are usually free to use.
Where can I find old pictures of my town?
Ask your local archive, history society or museum. Online, try the Library of Congress, Europeana, Wikimedia Commons and Histo.
How can I tell when a photo was taken?
Compare clothing, cars, buildings and signs, check postmarks and the back of the print, and match the scene with dated archive photos.
What resolution should I use to scan old photos?
Use 600 dpi for prints and 1200 to 4800 dpi for small photos or negatives, so details survive enlargement.
How should I store old photographs?
Keep them cool, dry and dark in acid-free materials. Avoid PVC sleeves, adhesives and direct sunlight.
Can old photos be restored or colorized?
Yes, editing software can remove cracks and stains. Always keep an unaltered scan of the original and label edited versions.
What are old postcards worth?
It depends on subject, rarity and condition. Rare street scenes of small towns often fetch more than famous landmarks.
What is a carte de visite?
A small portrait photo mounted on card, about 6 x 10 cm, hugely popular from the 1860s. Cabinet cards were a larger successor.
Can I upload my own old photos to Histo?
Yes. After free sign-up you can upload photos with year, place, story and optionally an address or GPS position, confirming you hold the rights or that the image is public domain.
Where do the pictures on Histo come from?
From public-domain collections of public archives such as Wikimedia Commons and the Library of Congress, and from our users.
Is Histo free?
Yes, exploring, uploading and commenting are free.
