Digitizing Photos and Documents for AlmaHistory.org: Quality, File Naming, and Preservation Tips

Digitization is preservation—and accessibility

Uploading to AlmaHistory.org is more than sharing memories. It’s creating a usable historical record. The difference between a quick phone snapshot and a well-digitized scan is huge: clarity, readability, and long-term value improve dramatically when you use a few simple best practices.

This guide focuses on practical digitization habits that balance quality with manageable file sizes and consistent organization.

Prepare items before scanning or photographing

Start with a gentle cleanup and a plan.

  • Remove dust with a soft, dry cloth (avoid liquids on old paper)
  • Handle photos by the edges to reduce fingerprints
  • Group materials by type: photos, letters, programs, certificates, clippings
  • Decide what context you need: envelopes, back-of-photo notes, captions

If a photo has writing on the back, digitize both sides. Those notes are often where dates, names, and places live.

Choose scanning settings that match the item

Resolution depends on what you’re scanning.

For printed photos:

  • Good baseline: 600 DPI
  • If the photo is tiny or you may crop/zoom later: 800–1200 DPI

For documents (typed pages, letters, programs):

  • 300 DPI is often sufficient for readability
  • Use 400 DPI if the text is faint, small, or you want better OCR

For newspaper clippings:

  • 400–600 DPI helps preserve thin print and texture

If you can scan in color, do it—even for black-and-white items. Color scanning captures paper tone, stamps, and annotations that grayscale can flatten.

File formats: prioritize quality first, then convenience

The best format depends on whether you’re creating an archival master file or an upload-friendly version.

Common best practice:

  • Archival master: TIFF or PNG (lossless, larger files)
  • Upload/share: JPEG (photos) and PDF (multi-page documents)

If you’re limited to one file per item, use high-quality JPEG for photos and PDF for documents, and keep originals backed up elsewhere.

For multi-page items like yearbook spreads or newsletters, a single PDF is often more convenient than dozens of separate images, as long as the text remains readable when zoomed.

Lighting and phone capture tips (when you can’t scan)

For more in-depth guides and related topics, be sure to check out our homepage where we cover a wide range of subjects.

Not everyone has a scanner, and that’s okay. Phone capture can be excellent if you control a few variables.

  • Use bright, even light (near a window, but avoid direct glare)
  • Keep the phone parallel to the document to reduce distortion
  • Use a neutral background and flatten the paper
  • Turn on grid lines to align edges
  • Use a document scanning app that auto-crops and straightens

Take a second shot if you see blur, glare, or shadow. Small defects become major frustrations when someone tries to read names later.

File naming that stays searchable for years

A consistent file name makes it easier to upload, audit, and re-find originals later. Choose a format you can apply quickly.

A reliable pattern:

  • YYYY-MM-DD (or YYYY-MM, or YYYY) + short description + source
  • Use hyphens, avoid special characters

Examples:

  • 1968-10-12-homecoming-parade-main-street-jordan-family.jpg
  • 1977-yearbook-senior-portraits-scan-library.pdf
  • 1984-05-spring-concert-program-original.jpg

If the date is unknown, use an estimate with a note in the description/caption, and consider a filename like “circa-1980s.”

Metadata: the details that make uploads valuable

On AlmaHistory.org, the biggest upgrade you can make is adding context. A photo without names is a dead end; a photo with names becomes a bridge.

Aim to include:

  • Names (and spellings) of people pictured
  • Event name and reason it matters
  • Location (building, town, campus)
  • Date or date range and how you know it
  • Source and rights/permission notes

If you’re unsure, say so. “Possibly 1972 based on the uniform style” is more honest and more useful than a confident but wrong date.

Quality control: quick checks before uploading

Before you upload a batch, do a fast review:

  • Can you read small text when zoomed?
  • Are faces clear enough to identify?
  • Are pages cropped too tightly (missing margins or notes)?
  • Are files rotated correctly?
  • Are filenames consistent?

Catching issues early saves time and reduces rework.

Backups: don’t rely on a single platform

Even when AlmaHistory.org is your publishing home, keep your original scans backed up. A simple “3-2-1” approach works well: three copies, on two different types of storage, with one offsite (like a cloud drive).

Digitizing takes effort. Backups protect that effort.

Make digitization a repeatable habit

The easiest way to build a rich AlmaHistory.org collection is to create a repeatable workflow: prepare, scan/capture, name files, add metadata, upload, and back up. You don’t need perfection, but you do need consistency. Over time, those consistent choices turn scattered memorabilia into a coherent, searchable archive.
