Fix Photos.app dates

I recently had a situation where I needed to fix the dates on some photos imported from Lightroom into Photos.app. For some reason, Photos.app had chosen the file creation date (which was the Lightroom export date), rather than the capture date stored in embedded exif data.

This script works after importing the photos, if you've already done some organising.

Usage

Put the photos you want to adjust into an album called "DateFix".

You'll need exiftool installed.

brew install exiftool

Make a scratch dir as per the first line of the script.

Then run the script. The photos will be adjusted to match the date in the EXIF data.

fix dates.scpt

-- create a folder for use by the script and set the path to it here
set thepath to alias "Macintosh HD:Users:joerick:Desktop:Scratch" as text

tell application "Photos"
	set photos to every media item of container "DateFix"
	repeat with mediaitem in photos
		tell application "Finder" to delete every item of folder thepath
		export {mediaitem} to thepath with using originals
		tell application "Finder" to set theExport to item 1 of folder thepath
		
		set theCommand to "/opt/homebrew/bin/exiftool -S -DateTimeOriginal " & (quoted form of POSIX path of (theExport as alias))
		
		set exifOutput to do shell script theCommand
		
		set resultDate to the current date
		
		
		--		set theyear to (text 19 thru 22 of exifOutput)
		--		set themonth to (text 24 thru 25 of exifOutput)
		--		set theday to (text 27 thru 28 of exifOutput)
		--		set thehours to (text 30 thru 31 of exifOutput)
		--		set theminutes to (text 33 thru 34 of exifOutput)
		--		set theseconds to (text 36 thru 36 of exifOutput)
		--		
		--		return theyear & themonth & theday & thehours & theminutes & theseconds
		
		set the year of resultDate to (text 19 thru 22 of exifOutput)
		set the month of resultDate to (text 24 thru 25 of exifOutput)
		set the day of resultDate to (text 27 thru 28 of exifOutput)
		set the hours of resultDate to (text 30 thru 31 of exifOutput)
		set the minutes of resultDate to (text 33 thru 34 of exifOutput)
		set the seconds of resultDate to (text 36 thru 36 of exifOutput)
		
		set the date of mediaitem to resultDate
		
	end repeat
end tell

Nice, thanks! Pleased it's helpful.
