Photoshop has an entire automation workflow that you can use to automate batch operations. It would be ideal for what you are trying to do here.
These batch operations are called Actions and you can get to them from the Windows...Actions menu.
You then make a new action
and name it.
You can then record the steps you want to do, opening the file, ...
One can utilize the Adobe Camera Raw(ACR) bundled with Photoshop
Elements(PSE),as if it were near-native to Bridge Creative Cloud(CC)
(read below for the caveats though, because there are some quirks and some things you cannot do)
What works and what doesn't
The Adobe Camera Raw included with PSE seems to be a separate instance from the CC ...
You can filter photos without a keyword in Bidge:
Navigate to the folder that has the photos with and without keywords.
Go to the Filter panel. If it's not shown, go to Window → Filter panel.
Click on No Keywords:
If your photos without keywords are spread out over multiple folders, you can go to the parent folder, enable Show Items from Subfolders and ...
Using Google seems to move the exact point to the nearest road, so if you are on a hill somewhere the co-ordinates will be a bit different for what you expect.
The best bet would be to use the method above
To convert a decimal longitude or latitude to degrees (minutes and seconds), simply take the first, whole, number and use it as the degrees. Then ...
The first screenshot has a resolution of 899 × 650 px. The second screenshot has a resolution of 1798 × 1300 px, which is exactly twice the resolution in both dimensions.
A 100% zoom of both screenshots will show the 2nd screenshot to appear twice as large (dimensionally), and the "Preview" areas will be identically sized.
I always just use LR and let it keep track. Stacks work nicely if it is primarily based on one image, though if you have combined multiple, perhaps either using keywords or putting it in some collection of edited works would fit well.
ACR is not a stand alone application, but a Photoshop/Bridge plug-in. But if the file extension of your raw files is associated with Photoshop, PS should load and the file should open immediately in ACR when you double click it from explorer.
Functionally, there is no difference then to your requirement.
What your own browsing program does is, of course, ...
My workaround is:
Do a keyword search for the moved word;
Select all the images that come up;
On the keywords panel, un-tick the italicised version of the keyword;
With the images still selected, tick the moved version of the keyword.
Delete the italicised work in the keywords panel.
So that way you keep all the images under the correct keyword and delete ...
The problem was solved by restarting Adobe Bridge and then clicking the little pen icon next to the metadata IPTC core info, and also waiting for the messages on the bottom left "Rebuilding index".
Also I had to use the menu find, not the quick search, and select "metadata" and check the box "include non-indexed files"
Wow, they really make it hard.
