ProofsheetWhy do old photos have an orange date stamp?
The orange date in the corner of many old prints was added by the camera. A date back inside the body shone light through small digits onto the film as each frame was exposed, so the numbers became part of the negative. Camera apps now copy the look with a date stamp setting.

Where did the date come from?
From the camera, at the moment you took the picture. Many compact film cameras of the 1980s to 2000s offered a date back, a small module with a clock and a display of digits. When the shutter fired, light from the digits exposed a patch of the film near the frame's corner.
Because the date was exposed into the film itself, it is part of the negative. No lab added it, and nobody could remove it without retouching.
Why is it orange?
The digits were lit with a red or orange light, and that light affects film in a way that gives a warm color on prints. Many cameras of the type used the same style, so the amber digits became familiar. Whatever the technical details, the look became the shorthand for a family snapshot from that era.
Some cameras let you choose between a day-and-month-and-year display, a time display or no stamp. Others had only an on-off switch.
How was the date set?
Most date backs had a small button or a hatch for setting the clock. If the owner forgot to set it, or the battery died, the date was wrong, and the wrong date stayed forever on every frame. This is why you will meet old prints with dates that make no sense.
A wrong date on a print is a nice reminder that the stamp was a record, not a guarantee.
Why do people want it back?
Because it gives a picture an instant context and a pinch of nostalgia. Even viewers who were not born when those prints were made recognize it. The numbers read as a note from the past, so the picture looks like a found object instead of a fresh digital file.
It also has a practical side: a dated frame helps you remember when something happened. Looking at a sheet from last summer, the dates tell you which frames belong to which day.
How do apps add the date stamp?
A date stamp setting draws digits onto the picture, usually in the corner and in amber. Some apps let you type any date. Others take it from the capture time of the frame, which is more honest. Proofsheet's stamp is amber digits drawn from the capture date, and it is a switch in the roll setup. Pro adds more date stamp styles. Read the film looks page for the other extras.
Settings has a default for new rolls, so if you like the stamp you can turn it on once. The camera screen shows a date stamp toggle when the roll allows it.
When is a date stamp a good idea?
| Roll | Stamp? | Why |
|---|---|---|
| Trip roll | On | Dates help sort the days |
| Week roll | On | Matches the Monday to Sunday markers |
| Portrait roll | Off | Digits compete with faces |
| Crew roll at a party | Host decides | The setting travels with the ticket |
| Art or product roll | Off | It reads as a gimmick |
Where does the stamp go on the picture?
In the lower corner, where the old cameras put it, and in amber. It sits on the finished frame, so it appears on the print and in exports. The stamp is applied when the roll develops, along with the look, so the viewfinder shows the plain scene while you shoot. If you want a clean copy, shoot another roll without it, because the setting is chosen when you load the roll.
Does a stamp work with a proof sheet?
Yes. The sheet shows each frame with its stamp, and the edge print and frame numbers sit around them, so the page reads like a lab sheet from the period. See the proof sheet page. The week roll adds day markers on top, which gives you two ways of seeing the date.
Is it honest to add a date stamp?
If the date is the real capture date, yes. It is a design choice, not a trick. An app that lets you set any date is also fine, as long as you know you are making a look and not a record. Proofsheet is not on the App Store yet, and its stamp comes from the real capture date.
Can I add one to a roll I already shot?
Not in Proofsheet. The stamp is a switch you choose when you set up the roll, and it is applied when the roll develops. Decide before you shoot. If you are unsure, a short roll without the stamp and another with it makes an easy comparison.
How do I make a dated set look consistent?
- Use the same look for the whole roll.
- Keep the stamp on for every roll in the set.
- Shoot a frame of a calendar, a ticket or a sign on the first day, as a title card.
- Use a week roll if you want the days laid out for you.
Why do the dates seem to shift on some prints?
Date backs imprinted whatever was set on the camera's clock. If the clock was off by a year, or reset to a default after a battery change, every frame on the roll carries the same wrong date. Sometimes the date also showed the day and month in a different order from what you expect. When you find an old family print, treat the stamp as a clue and not as proof.
