In photos for Mac, is there any way to create a smart album for images by file size or dimensions?

A few hours later…

Huzzah! A solution came from an unexpected source, Apple Shortcuts! With one caveat, I had to create the album to receive the images before running the shortcut, because it misbehaved otherwise. Once the images are in the album, I can use Photos.app to apply the keywords. Job done!

Dear Genie, I wish Photos.app could do this by itself. Life would be more pleasant.

I downloaded PowerPhotos, paying for the upgrade to the latest version. It can sort by image dimensions, and file size, but can't edit metadata such as keywords.

In addition, it crashed no less than 6 times in the first half-hour of use, every time I deleted a group of images. Even deleting a single image sent it into some sort of slow cycle resorting all the remaining images (about 4000). I feel I wasted my money, and I don't want to waste any more time on it. (My machine is a 2020 M1 Mac mini running Ventura)

Ideally, I want a way to sort images by file size and/or dimensions and to edit keywords to identify/categorise them appropriately so that I can collect them into smart albums in Photos.app, making final decisions about deletions etc later on.

With EXIFTOOL, I can achieve all of the parts of the process, including editing keywords, and any other metadata I like, but Apple Photos doesn't recognise the metadata unless the files are imported into the Photos library with the edited metadata already in place.

Any attempt to edit the keywords, or captions, or titles, etc. of images which are already in the photoslibrary by using a third-party utility which is capable of sorting by dimensions or file size, fails because Photos.app does not recognise/read the edited metadata, even though the edited metadata is there, which can be confirmed by searching through the photoslibrary with exiftool again.

Photos.app cannot search or sort images based on file size, or image dimensions, and will not recognise keywords, or other metadata in images already in the photoslibrary which are edited using any third-party utility I have found so far

My frustration is at mountaineer levels.

One further detail… this only works with the system photo library. Any other library you have created may have to be temporarily set as the system library to be processed this way.
