Step 1: Inspect the photograph before cleaning it
Work on a clean, dry, well-lit table, away from drinks, food, and direct sunlight. Hold the photograph by its edges and avoid touching the image surface. If it is curled, brittle, cracked, lifting, or stuck to an album or glass, do not force it flat, peel it away, or wipe it. Photograph its current condition first and, if needed, ask a photo conservator for advice.
Do not use water, alcohol, household cleaners, tape, or an eraser on the original. They can cause irreversible damage to the emulsion, coating, or already fragile paper. Remove nearby items such as paper clips before scanning, but do not risk the photograph itself just to make it look clean.
Step 2: Choose a way to capture it safely
A clean flatbed scanner can work for a small photograph in good condition that lies flat. Make sure the entire image fits without pressing on raised or curled edges. A camera mounted above the photograph or a phone stand is safer for fragile, bent, oversized, or visibly damaged prints. Do not feed a valuable original through an automatic document feeder.
You can make a useful family record with a phone if you do not have a scanner: place the photo on a matte, evenly colored background and keep the camera parallel to it. Use soft, even light; avoid flash and glare from glass. Clean the phone lens, focus, and check that all four corners are sharp. If you see perspective distortion, shadows, reflections, or blur, adjust the camera and light and take another shot. Cropping later cannot restore details that were never captured.
Step 3: Preserve enough detail and an untouched master
Choose scan resolution based on the print's size and detail, and on whether you may enlarge or print it. For its own digitization work, the U.S. National Archives gives examples of pixel targets by source type and size; a long edge around 3,000 pixels is one target for some photographs. This is not a universal rule for every device or family photo. Real optical capture, a sharp image, complete edges, and avoiding invented detail from upscaling matter more than a high DPI number shown by software.
When possible, keep an unedited, high-quality master. Lossless formats such as TIFF are useful for preservation; JPEG is convenient for browsing, sharing, and the web. If storage is limited, keep the master separate from copies made for sharing. Do not keep only an automatically enhanced, cropped, or denoised version: future edits should start from an untouched digital copy.
Step 4: Name it, add context, and make backups
Use a filename that will help you identify the photograph later. One practical pattern is:
year-person-or-event-place-number.tifFor example: 1968-grandparents-shanghai-01.tif. If the year is uncertain, write “circa 1960s” or “date unknown” rather than turning a guess into a fact. Record the people, place, date range, and source of the information in a sidecar note or photo-management tool. You can attribute a family memory to the person who shared it so it can be checked later.
Keep multiple copies—for example, one on your computer, one on an external drive, and one off-site or in a trusted cloud service. The U.S. National Archives recommends the 3-2-1 rule for family digital records: three copies, on two kinds of media, with one stored elsewhere. Occasionally check that important files still open instead of relying only on a “sync complete” icon. Digitizing does not make the paper original less valuable; store it safely afterward.
A quick check for each photograph
- The original was not pressed, rubbed, cleaned, or put through an automatic feeder.
- The image is complete and correctly oriented, with clear edges and no obvious glare or shadows.
- The original scan is saved separately and has not been overwritten by a repair or crop.
- The filename and notes distinguish confirmed details from guesses.
- Important photographs have more than one recoverable backup.
Digitize the original safely before repairing, colorizing, or making a display copy. A digital copy can be edited again; an original cannot be “undone” after careless handling.
