Is there a way to do batch changes in Photos (like we could in iPhoto)?

Question

I made heavy use of the Batch change command in iPhoto.
Now that I'm in Photos, how can I get the same results?
Specifically the Batch change of title....

Answer 1

To batch change the titles of selected photos to the same title you could try a simple Apple Script and run it with Automator.
Create an Automator action, that prompts you for the new title and executes an Apple Script to change the titles to the name you entered:
I put a copy of the finished workflow into my Dropbox, if you want to try it:  https://www.dropbox.com/sh/r6kf61oiktntt3q/AADJtXaEuB38OZY0H0PWEIPfa?dl=0
The Apple Script:
on run {input, parameters}
  -- batch chnage the title to the input
  tell application "Photos"
  activate
  set imageSel to (get selection)
  if imageSel is {} then
  error "Please select some images."
  else
  repeat with im in imageSel
  tell im
  set the name to input
  end tell
  end repeat
  end if
  end tell
  return input
end run
Launch Automator,
create a new service,
drag a "Ask for Text" action into the workflow.
drag a "Run Apple Script" action into the workflow.
Copy and paste the text above into the "Run Apple Script" action to replace the default text in the action.
Save this workflow with a suitable name.  It will be installed in the services.
Now quit Photos, if it is running and launch Photos again and select a few test images.
Open the "Photos" Menu > Services".
The service should be shown in the menu - I saved  my version as "BatchChangeTitles".
Select the service to let it run.
You will be prompted to enter a new title for the selected photos.
When you click the selected photos again, the titles should change.
