CalcLockAt a glance: Treat a burst as a set of candidate frames, not a single guaranteed import unit. Choose the moments you need in Photos, then verify the individual results.
Start with a reason to keep each frame
Burst mode is useful when timing matters: a jump, a moving pet, or a group whose expressions change between frames. After the moment passes, the burst can leave dozens of very similar pictures. Importing everything immediately makes private browsing more cluttered and later comparison harder.
Decide whether you need one best photograph or a short visual sequence. For a portrait, one frame with clear eyes may be enough. For an action reference, several distinct positions may matter. Those choices are more useful than an arbitrary instruction to keep every tenth image.
Review the burst at a useful size
Open the burst in Photos and use its frame-selection controls. Apple describes selecting individual images from the burst; labels can vary with the iOS version. Inspect faces, hands, motion blur, and important details in the background rather than relying solely on suggested picks or small thumbnails.
For a sequence, choose frames that show meaningful changes, not several pictures of essentially the same pose. Keep a wider-context frame when it explains the scene. Do not discard the rest of an irreplaceable burst before you are satisfied with the selection and your source-copy plan.
Make the selected files easy to identify
Once you have individual candidates, count them and note their capture time or position in the event. If several are nearly identical, compare a distinctive detail before importing. A simple source album can help with selection, but remember that organizing a library does not itself create an independent archive.
Use a harmless burst first if this is your first attempt. Importing a burst thumbnail is not proof that every underlying frame will appear as a separate vault item. Verify the behavior of your actual selection path instead of assuming the app reproduces the Photos burst interface.
Check the destination by identity, not count alone
Open the intended CalcLock vault with its exact expression and two consecutive equals presses. Import the selected images, then compare them with the chosen source frames. Count the results, but also check identity: three copies of one frame are not the three different moments you intended to keep.
Look at the details that drove your selection, including whether the subject is sharp and the expression is correct. If something is missing, recheck the source selection before attempting another batch. Repeatedly importing the full burst can turn a small uncertainty into a confusing collection of duplicates.
Keep the source for later decisions
Your favorite frame can change when you revisit the photographs or need a different crop. Retain important source material independently, especially if the event cannot be repeated. CalcLock has no export, backup, restoration, synchronization, or forgotten-equation recovery, so it should not become the only place those selected moments survive.
After checking the import, organize the remaining source files deliberately. Distinguish a rejected blurry frame from a frame you simply did not need today. There is no need to rush a destructive cleanup in the same session as an unfamiliar import workflow.
Questions, answered
Should every burst frame become a vault item?
Only if you actually need them and have verified how they import. A small, intentional selection is often easier to inspect and browse, while an independent source archive preserves options for later.
