Scan them yourself, or pay someone?

This is a genuine arithmetic question with a genuine answer, and it is almost never the answer people expect. It depends on three numbers: how many photographs you have, what resolution you actually need, and what an hour of your time is worth to you on a Sunday.

01 The routes

Three ways, and what each is really for.

RouteSpeedQualityUse it for
Phone camera Fastest — 15–30 seconds each Fair, with perspective correction and flat light. Poor for small prints and glossy surfaces Contact-sheet records, sharing, triage, albums you cannot disassemble
Home flatbed scanner 60–90 seconds each including handling Best available for prints Small prints, anything you will reprint, your final archive copies
Mail-in or shop service Days to weeks, plus shipping both ways Consistent and high, automated dust removal, handles batches Large collections, negatives, slides, anything delicate

The important thing about the phone route is not that it is worse. It is that a phone capture is a photograph of a photograph, not a scan, and the difference matters later when you try to restore from it. More on that in section 05.

02 The math

Five hundred photographs, three ways.

Take a realistic box: 500 prints. Here is what each route actually costs, counting your time at something honest — say $25 an hour, which is well below most professional rates and generous to the DIY case.

RouteTimeCashTotal realistic
Phone, 25s each~3.5 hours$0About 3.5 hours, and a mediocre archive
Flatbed, 75s each incl. handling and editing~10.5 hoursCost of a decent scanner, often $100–$300Two or three weekends, plus the hardware
Mail-in service, roughly $0.30–$1.50 per printAn hour of packingRoughly $150–$750About an hour, plus shipping risk and waiting

The crossover is roughly 100 to 150 photographs. Below that, DIY is usually right because the setup cost dominates. Above that, the arithmetic starts favouring a service — not because your time is more valuable than money, but because almost nobody actually finishes a ten-hour scanning project. The failure mode of DIY scanning is not slowness. It is abandonment at photograph 200, which leaves you with a half-scanned collection and a scanner in a cupboard.

Honest adjustment: if you enjoy the work, or you have a scanner already, or the collection is small and precious, DIY wins on more than arithmetic. The numbers above assume you are scanning unwillingly.

Hours of your own time against collection size Line chart. A phone camera takes about 3.5 hours for 500 photographs and a flatbed scanner about 10.4 hours, both rising straight with collection size. A mail-in service costs roughly one hour of your time regardless of how many prints there are. 0 2 4 6 8 10 12 0 100 200 300 400 500 photographs in the collection hours of your own time mail-in service — about 1 hour phone camera — 3.5 hours flatbed scanner — 10.4 hours
A hundred prints is a weekend on a flatbed. Five hundred is a month of evenings.
03 Resolution

The DPI you actually need, by purpose.

Most people scan at the wrong resolution in one of two directions: 300dpi for everything and then discover they cannot reprint, or 4800dpi for everything and fill a hard drive with files nobody will ever open. Match the resolution to the job.

PurposeDPINotes
Screen, sharing, family group chats300Plenty. Do not bother higher
Reprint at original size600The sensible default for a family archive
Enlargement, or small prints (under 4×6in)1200Small originals carry fine detail worth capturing
35mm negatives and slides2400–3200A 35mm frame is tiny; it needs the resolution
Large format negatives, glass plates1200–2400The physical area is already large

Those are working numbers for a family collection. The formal benchmark is higher and worth knowing: US federal regulation 36 CFR 1236.50 sets a floor of 400 ppi for photographic prints, mapped to the FADGI three-star category, and archival practice for 35mm film sits above the range in this table. Scan above the floor if the time is available; scan at the floor rather than not at all.

Scan as a TIFF or a high-quality JPEG, not as a screenshot, and never resize down before archiving — the small version is easy to make later and impossible to recover.

04 Negatives

Negatives and slides are a different job entirely.

This is where DIY usually fails and where paying is usually correct. A negative is a transparent original: it needs light passed through it, which means a transparency adapter, a dedicated film holder, and usually software that inverts and colour-corrects the result. A flatbed without a transparency unit will produce a black rectangle.

Two things follow. First, if you have the negatives, they are frequently a better source than the prints — they are first-generation, usually less faded, and often include frames that were never printed. If a family collection contains a shoebox of negatives alongside the prints, that shoebox is the more valuable object and most people do not know it.

Second, film scanning rewards proper equipment. A service with a dedicated film scanner will beat a home flatbed on 35mm by a wide margin, and the cost per frame is low because the handling is fast. For anything more than a handful of strips, pay.

05 The trap

A photo of a photo is not a scan.

The most consequential mistake in this whole process happens before any restoration. Someone holds a phone over a print, takes a picture, and that file becomes the thing everything else is built on. It has four problems baked in that no amount of restoration can remove:

  • Perspective. The print is never perfectly square to the lens, so the image is a trapezoid. Correction helps but resamples every pixel.
  • Glare and reflection. A glossy print lit by a window or a ceiling bulb has a hotspot over part of the image — often over a face. The information there is gone.
  • Curvature. Old prints are rarely flat. A curled print has parts out of focus that no sharpening recovers.
  • Moiré and softness. The camera resolves the paper texture and the print's own dot structure, and the result is a soft, patterned image at a fraction of the detail a scanner captures.

So: if the only version you have is a photo of a photo, the correct first step is not restoration. It is getting a proper scan. Restoration from a bad capture is expensive, and the result will be invented detail layered on missing detail. Our triage tool will tell you this outright if you select it, because it is the most common way people waste money on restoration.

If a proper scan is genuinely impossible, the acceptable middle ground is a phone capture done properly: the print flat on a table, camera parallel and directly above, diffuse daylight from a window with no direct sun, flash off, and a scanning app that handles perspective and colour. It will not equal a flatbed, but it is not a snapshot either.

06 Decide

The short version.

Pay a service when: you have more than about 150 photographs; there are negatives or slides; the albums cannot be disassembled; the material is delicate, mouldy or pre-1900; you have a deadline — a funeral, an anniversary, a birthday; or you know you will not finish it yourself.

Do it yourself when: the collection is under about 100 prints; you already own a scanner; you only need screen-resolution copies; or you want to handle the prints yourself because they are fragile or you do not want them to leave the house.

Never: send irreplaceable originals by post without insurance and tracking, or accept a "we scan it and keep the originals" arrangement from an unclear provider. Ask what happens to the paper and get it in writing.

Once you have the files, the rest of the work is sorting and storage — and if some of what you scanned is damaged, here is what restoring it costs.

Questions

The things people ask next.

Is it cheaper to scan old photos myself or pay a service?
Below roughly 100–150 photographs, doing it yourself is usually cheaper, because the setup cost dominates. Above that, a service at roughly $0.30–$1.50 per print competes well against ten or more hours of flatbed work — and the practical argument is that most people abandon DIY scanning partway through.
What DPI should I scan old photos at?
300dpi for screen use and sharing, 600dpi as the default for a family archive you may reprint, 1200dpi for small prints and enlargements, and 2400–3200dpi for 35mm negatives and slides. Archive as TIFF or high-quality JPEG.
Can I scan old photos with my phone?
For records and sharing, yes — with the print flat, the camera parallel and directly overhead, diffuse daylight and no flash, using an app with perspective correction. A phone capture is a photograph of a photograph, though, and it is a poor source for restoration because of glare, curvature and lost detail.
How do I scan negatives and slides at home?
You need a scanner with a transparency adapter and a film holder, because light must pass through the negative. A standard flatbed without a transparency unit will produce a black image. For more than a few strips, a service with a dedicated film scanner is usually the better route.
Should I send my only copies to a scanning service?
Only with insurance and tracking, and only after confirming in writing what happens to the paper afterwards. For irreplaceable prints, scan the significant ones yourself even if the result is slower and imperfect.

Scanned, and now wondering whether to restore?

Most damaged photographs are not worth a professional restoration — and some are worth far more than you would expect. Thirty seconds to find out which.
