Sequencing scanned images after importing to Photos
When scanned photos are imported into Photos via the Import function, the date of the photo is the date it was scanned. The scanned photos are many years old but now have a current date. I can change the date on each one individually. That's tedious. When I batch change the date, Photos applies the same time period offset to each of the photos. That puts me at the mercy of when they were scanned which is not necessarily in the desired order. I used to be able (perhaps as long ago as iPhotos but I think more recent) to batch change several photos at once and there was an option to add a fixed number of minutes/hours/days to the balance of the photos in the batch. I can't find a way to do that now. Has the adding of an incremental time period been deleted as an option in Photos? I'm using a 2018 MacBook Air running macOS Catalina 10.15.4 with Photos 5.0.
What I'm trying to do is batch change the date on several photos at once and give the first photo in the batch a specific date/time. Then have Photos automatically add a specified time increment to the remaining photos in the batch. Thanks for any help provided.
