A shoebox of prints, a flatbed and a phone: how to scan photos starts with matching the method to each photo’s condition and end use. For prints, set 600 PPI, or 300 PPI if you will never print larger than the original.
Scanning is the first step of the wider workflow in our guide to photo editing for beginners, which picks up once the digital files exist.
What DPI for scanning photos?
For reflective prints, scan at 600 PPI, and drop to 300 PPI only when you will never reprint larger than the original. Rocky Nook’s scanning guide also clears up the terminology: DPI measures the quality of printing, not scanning, so resolution advice for scans is best read as pixels captured per inch of the original.
Most resolution mistakes come from a few common beliefs, set against what the evidence supports below.
| Common belief | What is supported | Planning use |
|---|---|---|
| DPI rates how good a scanner is | DPI measures print density, not scan quality | Treat the number as a capture setting, not a quality score. |
| Higher is always better | 600 PPI is the upper limit of detail for most prints | There is no reason to push prints past 600 PPI. |
| 300 is too low for family photos | 300 PPI is sufficient if you never reprint larger than the original; CNET suggests at least 300 dpi, up to 600 dpi for enlargements | Use 300 for same-size copies and move toward 600 when you plan to enlarge. |
| One setting suits every format | Slides and negatives call for 4000 PPI, while prints call for 600 PPI | Scan transparencies as a separate batch at the higher setting. |
Resolution figures come from Rocky Nook’s scanning guide and CNET’s guide to scanning and archiving printed photos.
The practical reading is simple. Albums you might crop, enlarge or restore justify 600 PPI. Picture Keeper also sets 300 DPI as the minimum, so treat 300 as the floor for keepsakes rather than the target. Once the capture setting is decided, the next choice is the device that will do the scanning.
Flatbed or sheet-fed?
Choose a flatbed when photos are fragile, mounted or oddly sized, and a sheet-fed scanner when prints are sturdy, uniform and numerous. The common misunderstanding is that a sheet-fed model is simply a faster flatbed. The two handle the original very differently, and that difference should drive the decision.
Flatbed scanners
A flatbed holds the print still on the glass while the scan head moves beneath it, which makes it the lowest-risk route for original prints. It suits creased, curled-then-flattened, mounted or irregular photos, and anything you may want to restore later. It is slower per photo, but the resolution settings in the table above apply directly, and you can reposition a print and rescan it without stress on the paper.
Sheet-fed scanners
A sheet-fed scanner pulls each print through a feed path, so the original is moved, bent and gripped as it passes. That suits a stack of sturdy, similarly sized prints where throughput matters. It is a poor match for brittle edges, mounted prints or photos stuck to their neighbours.
A quick way to decide between the methods:
- Fragile or mounted prints: use a flatbed, even though it is slower.
- Large stacks in good condition: a sheet-fed scanner saves hours if you accept the handling.
- Mixed collections: sort by condition first, then send only the sturdy prints through the feeder.
Scanning with your phone
A phone is the right tool for quick sharing and for copies of prints you cannot bring to a scanner. Its main limit is lighting, which you control rather than a scan head. CNET advises finding a well-lit area with plenty of natural light and few shadows, and the steps below follow that principle.
- Choose the light: work near a window or in even daylight so the print has few shadows.
- Lay the print flat: use a plain, uncluttered surface and flatten any curl first.
- Hold the phone parallel: keep the camera square to the print so the frame does not skew.
- Let the app correct the frame: use its edge detection and perspective correction, then check for glare and reflections before saving.
For prints you might enlarge or restore, a flatbed scan at the settings in the resolution table gives you a master whose capture settings you chose. Phone copies fit a family chat or an email far better than a long-term archive. When a phone snapshot of a print has a distracting backdrop, How To Blur The Background Of A Photo You Already Took: Easy Steps For Phone, Desktop & Web (2026) shows how to soften it.
TIFF masters and sharing copies
Save the master as a TIFF with lossless ZIP compression, which Rocky Nook recommends for the highest quality. The common mistake is saving a single compressed copy and editing it in place, which leaves no clean version to return to.
Keep the TIFF untouched and do your editing on duplicates. Export smaller copies from those duplicates whenever you need to share. If you already work with detailed originals, the habits in How To Edit RAW Photos: A Practical Workflow To Unlock More Detail In 2026 carry over naturally to scanned masters, because both rely on keeping the source file intact. Preparing the print properly, as the next section explains, matters as much as the file format.
Preparing fragile prints and planning restoration
Sort prints by condition before the first scan, because condition decides both the scanner and how much cleanup the file will need. Check each photo for tears, dust and stuck layers, and separate stuck prints gently rather than pulling them apart. Wipe the scanner glass and brush dust from the print with soft, lint-free tools, and keep liquids away from the originals.
Photo restoration starts with a clean, accurate scan. Do the repair work on a copy, keep the master unedited, and keep both files together so the pairing is obvious later.
Backing up and organizing scans
Follow a backup rule: keep several copies of every master, hold them on different kinds of storage, and keep a copy offsite. A single external drive on the same shelf as the originals protects against very little. Check restores occasionally so you know the copies open.
Organization is what makes the archive usable years from now:
- Name files consistently: a pattern such as YYYY-MM-DD_Event_Person sorts chronologically and tells you what each file shows.
- Add metadata immediately: record dates, names and places while the details are fresh, before the batch grows.
- Mirror how you search: group folders by year, event or person, whichever you use to look for photos.
- Cull duplicates early: remove accidental rescans while the batch is still small.
Frequently asked questions
| Question | Answer |
|---|---|
| How do I place prints on a flatbed, and how many fit? | Place each photograph face down on the scanning surface. On an average bed, you should be able to scan four 4×6-inch photos at once. |
| Can restoration make a damaged print look like the original? | Rocky Nook says archival scanning and expert restoration can give you digital images as good as the originals. Work on a copy so the unedited master stays available. |
| Do scanned files need a backup if I keep the original prints? | Yes. Picture Keeper’s advice is to always back up your photos and files. The digital masters are the copies you will edit and share, so they need protecting as well. |
