You have opened a cardboard box from the attic and found dozens of faded prints, some still attached to their original backs, others bent or stained. The goal is to turn these physical memories into digital files that can be accessed without risking further loss. The process starts before the scanner is even turned on, with a quick pass to weed out duplicates and identify the most fragile items. A systematic approach saves time, protects the originals, and creates an archive that remains usable for decades.
Sort and cull before you scan
Lay the photographs on a clean surface and separate them into three piles: keep, duplicate, and discard. Keep only one copy of each image, even if several prints exist; the extra copies can be stored later or given away. Flag any that are torn, water‑damaged, or have missing corners. This single pass reduces the number of scans, prevents unnecessary handling of delicate prints, and gives a clear inventory for later reference.
Checklist:
1. Remove obvious duplicates.
2. Set aside damaged items for special handling.
3. Note any prints that have writing on the back.
4. Create a simple inventory list with brief descriptions.
Set up the flatbed scanner
Place the scanner on a stable table and clean the glass with a lint‑free cloth. In the scanner software, choose a color mode of 24‑bit RGB for color photos and 8‑bit grayscale for black‑and‑white images. Turn off any automatic color correction or dust‑removal filters, as they can alter the original tones. Set the output file size to a moderate level—typically a medium compression JPEG for a quick preview, and a lossless option for the final archive. Adjust the exposure and contrast only if the preview shows obvious under‑ or over‑exposure; otherwise keep the defaults to preserve the original look.
Tip: Keep the scanner lid closed during each pass to avoid stray light that can cause uneven illumination.
Choose the right scanning resolution
A resolution of 300 dpi captures most printed photos with sufficient detail for everyday viewing and printing. At 600 dpi the scanner records twice as many pixels per inch, which is useful for small prints, text‑heavy images, or when you plan to enlarge the photo later. Higher resolutions increase file size dramatically and can expose grain or film artifacts that were not visible at lower settings. Reserve 600 dpi for images with fine detail, handwritten notes, or when the original is very small; otherwise stick with 300 dpi to keep storage manageable.
When in doubt, scan a representative sample at both settings and compare the results before committing to a single resolution for the entire batch.
Select a permanent file format
TIFF stores the image without compression, preserving every pixel and color value. JPEG reduces file size by discarding data, which is irreversible; each time a JPEG is edited and saved, quality degrades. Because the choice of format cannot be changed later without re‑scanning, use TIFF for the master archive and keep a JPEG copy for quick sharing. If storage space is a concern, consider a lossless format such as PNG for color images, but be aware that PNG files are larger than JPEG and may not be supported by all archival software.
Remember that the master file should be stored on a reliable medium and backed up separately.
Name files consistently as you scan
A clear naming convention prevents confusion when the collection grows. Use a structure that includes the event or location, the year, and a sequential number, for example: 1975_GrandCanyon_001.tif. If the photo has a known subject, add a short descriptor after the number, such as 1975_GrandCanyon_001_JimAndSue.tif. Keep the naming scheme simple, avoid spaces, and limit characters to alphanumerics and underscores. This format works on any operating system and remains readable for decades.
Example naming checklist:
1. Year (four digits).
2. Location or event (no spaces).
3. Sequential number, three digits.
4. Optional brief descriptor.
5. File extension matching the chosen format.
Handle fragile or damaged photographs carefully
Place a piece of clean, acid‑free tissue paper under a torn or brittle print before scanning to support the surface. Use a soft brush to remove loose dust; do not wet the image. If the photo is stuck to its backing, try to loosen it gently with a thin, flat tool, but stop if resistance is felt and seek professional conservation advice. For heavily water‑damaged prints, scan the image while it is still flat, even if the surface is uneven, and note the condition in the inventory.
Never apply pressure with the scanner lid on a fragile print; instead, keep the lid slightly raised or use a low‑profile scanner that does not press down hard.
Record information on the back of prints
Many photographs carry dates, names, or anecdotes written on the reverse side. Before scanning the front, photograph the back with a smartphone or a flatbed scanner set to a low resolution (150 dpi) and save it as a separate file, for example: 1975_GrandCanyon_001_back.jpg. Include the back image in the same folder as the front scan and reference it in the file name or a companion spreadsheet. This practice captures data that may not exist elsewhere and ensures that future researchers can link the two sides without handling the original again.
If the writing is faint, increase the contrast in the preview only for the back scan; do not alter the front image.
Store the originals after digitisation
Even after a high‑quality digital copy exists, keep the physical photographs in a cool, dry place away from direct sunlight. Use archival‑grade boxes or sleeves that are acid‑free and breathable. Avoid plastic bags that can trap moisture. Label the storage container with the same naming convention used for the digital files, so the physical and digital collections stay aligned. Holding onto the originals preserves the tactile artifact and provides a backup in case digital files become corrupted.
Do not discard the originals until you have verified that each scan is complete, correctly named, and backed up in at least two separate locations.
Worth remembering: A single, well‑planned pass that removes duplicates, uses a consistent scanner setting, and saves each image as a lossless TIFF with a clear, date‑based name creates an archive that stays usable and searchable for decades.
Common questions
What format or settings should I use?
Save the master copy as a lossless TIFF at 300 dpi for most photos, and use 600 dpi only for small or detail‑rich images; keep a JPEG version for quick sharing.
How should I label the files or items?
Adopt a simple scheme like YEAR_LOCATION_SEQ[_DESCRIPTOR].ext, for example 1975_GrandCanyon_001_JimAndSue.tif, and avoid spaces or special characters.
How many backup copies should I keep?
Store at least two copies of the master archive on separate media, such as an external hard drive and a cloud service, and keep the originals in archival storage.
