Photos not showing up in chronological order in which they were made

Where are you looking at photos in Photos?

The album "All Photos" should be sorted chronologically by the time the photos have been taken, the albums "Recents" and "Imports" will be sorted by the date the photos have been added.

Any album you create yiurself can be sorted by the date taken.

It is still working for me as expected.

Have your photos been taken in a different time zone then the timezone where you imported them?

Then you may need to fix the timezone for the photos taken with your external camera.

At least, check which timezone has been assigned to your camera photos and compare it to the timezone assigned to the photos taken with your iPhone at the same location.

You can see the timezone, if you select a photo and then open the command "Image > Adjust Date and Time". You will se the timezone strip and the closest city. Is this correct for the way the clock has been set in the camera? If not, you need to adjust the timezone for the photos taken with that camera to get them in line.

" In specific albums, it has become impossible to classify photos in the chronological order in which they have been made. I called the Apple Customer Service, and got the "diplomatic" answer that it is now expected that photos should appear in the order in which they have been added (not sure why, maybe a crazy engineer @ Appel thought this should be right...)"

Can you give us an example of the "Specific albums", where the sorting is wrong?

The Shared albums are showing photos in the order they have been added, unless we sort them differently, also Recents, and Imports, but not "All Photos". The albums in the Media section (Selfies, RAW, etc" are all sorted by "Oldest first".

For any album you can see, what the predefined sorting is supposed to be, by selecting the album and going to the menu "View > Sort". If the album cannot be rearranged by the user, the default sorting for the album will be shown, greyed out. This way you can check, how the album is supposed to be sorted.

For example, the sorting of the Media Type > Videos album: It is sorted "Oldest first".

And the sorting of "All Photos", also sorted by Oldest First:

This seems so much like a time zone issue! Cameras, and even phones, sometimes record the time zone is different ways, and Photos may not interpret the time data as the manufacturer intended. Since the differences depend on the camera, you might be able to just change one camera to match the other. You can use a Smart Album like this:

to gather pictures in an album a-ll from the same camera. Then you can use "Image>Adjust Date and Time..."

to fix the time on just the images from that camera. If you select all the pictures, it will show the date and time for the first one. Just highlight the hour and click on the little up or down arrow to get it right. All the pictures will have only their hour changed by the same amount.

That sounds crazy. As léonie as said, "It is still working for me as expected." For me, too. So what we expect and what you expect seems different from what the Apple person expects. Weird.

But what we see as the time & date may not be what Photos sees. When you look at the Info Window (⌘-i) is the time and date what you expect? It's possible Photos somehow lost track of the creation date and substituted a "Last Modified" date, or something like that.

Did you do anything unusual during the upgrade to Ventura? Do you have a backup from before the upgrade?

Have you checked the Info pane for those photos that are not listing correctly to see if the date is correct. Or if not how much is the date/time off? Which camera are the errant photos from - the external camera or your iPhone?
