Five minutes. You only do this once.
Work.Work Photos or your shared team folder). Create it now so the shortcut has somewhere to put things.Open the Shortcuts app (it's already on every iPhone), tap + to create a new one, and name it Upload Work Photos. Add these three actions in order.
is → Work.Dropbox / Work Photos folderAdd a couple of photos to the Work album, then tap the shortcut once. They should appear in your Dropbox folder within a few seconds. If they do, you're done building.
This is what makes it hands-off. Set it once and forget it.
1:00 AM → Daily.Everything above runs itself. These are the two small things a human still does.
In Photos, select the work shots → Share → Add to Album → Work. That selection is the work-vs-personal decision. Personal photos you don't add simply never leave your phone.
Open the Work album, select all, and remove them from the album (this does not delete them from your phone or from Dropbox). It just keeps the nightly upload quick instead of re-scanning old shoots.
A couple of choices look odd until you know the reason. Both make it more reliable, not less.
With Overwrite ON, the same photo keeps the same filename, so re-running just overwrites itself. That means no duplicates, a missed night catches up on the next run so nothing is ever lost, and photos you file late (shot days ago, added today) still upload. The "only new" version looks cleaner but quietly skips late-filed photos.
It can't, and it shouldn't try. You already know which photos are work, so you make that call in one tap. Nothing scans your family photos, and nothing personal ever lands in the work Dropbox.
Skip the album and the schedule entirely. Make the same shortcut a Share Sheet action instead:
In the shortcut's settings, turn on Show in Share Sheet and set the input to Images. Then your flow becomes: select work photos in Photos → Share → Upload to Dropbox.
One tap, instant, no scheduling, no weekly cleanup. The trade: it's "one deliberate tap when you choose" instead of fully automatic overnight. Pick whichever fits how you work.
Same idea, different tool. Install the free Autosync for Dropbox app, point it at a chosen camera folder, and it auto-syncs that folder to a Dropbox folder. Save your work shots to that folder and they back up on their own.
