CalcLockAt a glance: Keep a faithful master, record what is known and prepare separate sharing copies without turning uncertain family details into facts.
Start with a small, identifiable batch
Choose a group of physical photographs that belongs together and keep it organized while you work. Photograph or scan the front clearly, then record any meaningful writing on the reverse as a separate image. Use a stable surface and even light; check glare and cropping before repeating the process for a whole box.
Do not assume the first digital preview shows everything. Open the saved result and examine faces, handwriting and edges. If a photograph is fragile, avoid forcing it flat or using a method that could damage it. Seek appropriate preservation advice before handling valuable or deteriorating originals.
Keep observation separate from memory
Record the names, approximate date and location only to the extent they are known. A note such as “possibly taken in 1978” is more useful than an unsupported exact date. Distinguish writing found on the original from a later relative’s recollection, and keep both when they add context.
Give each physical photograph and its digital files a matching identifier. This makes it possible to connect the front, reverse and notes without relying on the order in a gallery. A photo’s digital creation date may describe the scan session rather than the original event, so it should not silently become the historical date.
Preserve a master before editing
Keep the highest-quality usable capture as your master and create separate copies for cropping, brightness adjustments or sharing. A smaller copy can be convenient to send, but it should not replace the source if you may later want a print or closer inspection. Avoid repeatedly saving over the same file while experimenting.
Record which version contains edits and what they were intended to change. A retouched mark or removed background object can change how someone interprets a scene. If historical fidelity matters, make the unedited master available to the people maintaining the archive, with appropriate permission.
Choose the audience deliberately
Family photographs can include people who do not want a public copy, addresses, letters or other personal context. Ask before posting a sensitive image broadly, and consider whether a small private group is the intended audience. Do not treat possession of a physical print as blanket permission to publish every detail it contains.
Apple explains that shared photo files may include associated metadata. Review sharing settings and prepare a separate publication copy when necessary. A cropped or redacted version can limit visible details, but inspect the actual exported copy and remember that recipients may retain it.
Make the archive outlast one phone
Store masters and contextual notes in a workflow that provides independent copies and a usable export path. Test access from the location or device the future custodian would actually use. Keep a simple explanation of the naming scheme alongside the collection so its meaning is not dependent on your memory.
CalcLock can hold selected local viewing copies, but it is not a family archive or inheritance mechanism. It has no export, account recovery or portable backup. Preserve the original photographs and digital masters independently; a collection visible behind an equation today is not a plan for another person to retrieve it later.
Questions, answered
Should CalcLock be the only copy?
No. Keep independently accessible originals. CalcLock is a device-only viewing collection without export, backup restoration or forgotten-equation recovery.
