Yes. A careful phone capture can be a useful source for a family film. Place the album on a stable surface, light it evenly and hold the camera directly above the photograph. The test is simple: can you see the important faces clearly when you enlarge the saved file?
Set up one comfortable spot
Use soft light rather than a bright lamp reflected directly in the print. In an ordinary camera app, turn the flash off if it makes a white patch. Move the light or album until the reflection disappears. Keep the phone parallel to the photograph; photographing from the side makes one edge narrower and can distort faces.
Clean the camera lens. Tap the face or central part of the print to focus, steady the phone, and take two shots. Choose the sharper one afterwards. Use the main camera rather than digital zoom. Move closer while keeping the whole photograph in the frame.
Photograph one picture at a time
A full album page is useful as a record of the original order, but a separate capture of each photograph gives the editor a better source. Do both when you can. Include handwritten captions in another image instead of making every picture tiny just to fit the entire page.
If a transparent sleeve causes glare, remove the print only when it slides out easily and safely. Do not pull a photograph from a stuck or brittle page. You can capture it in place and note the limitation. For valuable or fragile material, ask a conservator before trying to separate it.
A scanning app has different instructions
Google PhotoScan captures several positions and combines them to reduce reflections. Its own instructions may differ from an ordinary camera setup, including its flash guidance. Follow the app's current steps when using that mode. Compare its result with a normal photograph; one method may preserve a particular face better than the other.
Send the actual file
After capture, keep the original image file. A screenshot of the image preview or a heavily compressed forwarded message loses detail. Ask relatives for their original file when possible, and avoid applying beauty filters, automatic face replacement or dramatic color effects before upload.
Meaavar already describes phone photography as an option in its preparation guidance. That does not mean every phone capture will restore equally well. Severe glare can hide information completely. If an important portrait fails the full-size check, reshoot it before you submit the set.
A useful final check
Read the filename, open the image and compare it with the paper print. Make sure left and right have not been mirrored, the face is sharp and no part of the photograph is missing. Keep one album-page reference so the family can revisit the original arrangement later.
