Copy Photo Caption to Title with Applescript

Here is what I was looking for:

var photos = Application("Photos").selection()

this.console.log(`Changing ${photos.length} photos!`)

var count=0

for (const photo of photos) {

let datename = photo.date().toISOString().replace("T","_").replace(/:/g,"-").replace(/\..+/,"")

photo.name = photo.description() ? datename.substring(0,10) + " - " + photo.description() : datename

count++

console.log(`Renaming ${count} of ${photos.length}, new name ${photo.name()}`)

}

console.log(1)

First of all, thank you. This is very helpful. Unfortunately I don't know Apple Script to modify to what I am looking to do, which is:

1. For a given photo with a default title (e.g. IMG_5327.jpg)
2. Extract the Caption EXIF data (<Command+I> when I have a given photo selected "Enter a Caption" is the default)
3. Replace the existing title with that information
4. If the Caption field is empty, replace Title with YYYY-MM-DD_HH-MM-SS"
5. Keep extension as appropriate (e..g JPG)

I'd be really interested if something like this was possible and most grateful if it's possible to share something that's a bit more rudimentary for a novice like me to follow.

Sure! Attached are two screenshots with photos from day before yesterday.

1. Photo of menu - with the Info panel open. No caption (https://www.dropbox.com/s/wupit8nkencx952/Photo%201.pdf?dl=0)
2. Photo of of rain in Singapore - with the info panel open and caption "raining at the zoo" (https://www.dropbox.com/s/uc47u1bviw207zy/Photo%202.pdf?dl=0)

What I'd like to do is run a script that will change the title of the photo from IMG_5301.jpg to "Raining at the zoo" ... and if there is no caption (e..g Photo 1.pdf), then I'd like the file to be 2020-12-26_15-03-38.jpg (let's pretend that the YYY-MM-DD and time when the photo was taken.
