My workflow from an SLR and a small camera is simple. Once a month, I take the SD card out, insert it in my Macbook, and Photos can (usually) correctly detect the new photos. I copy them to the Macbook, back up to Time Machine. Once every three or so months, I wipe out the SD card.
It's seamless enough.
I am having trouble finding a reasonable workflow for my Android phone. The photos are synced with both Google Drive and with Dropbox. I'd like a workflow that uses either of the two, ideally one that wipes out my cloud-based photos as well as my Android-based photos, and detects and copies the new photos only.
Can you suggest such a workflow?
Update
In theory I could 1. copy the file from Google Drive to my Macbook and 2. then figure out how to convince Photos to copy the new pictures from a folder rather than from an SD card.
The first step can in theory be done by selecting the photos since my last copy (to be figured manually), then select the download
option from the context menu.
Unfortunately this complains that
"zip failed: no files to include"
Best Answer
It's simpler and faster if one uses neither Dropbox nor Google Drive.
Photos \ File \ Import does it. The catch is that when you connect your Android phone to your Mac(Book), Android's filesystem will not be mounted.
The solution is to first use
Android File Transfer
to copy the directory DCIM \ Camera to the Mac. Then you can import it.
