How do I scan photos in alphabetical order?

Scan photos as you have them, trying to keep similar events in time together. Then send them to Timeline Scan to date them so they're in chronological order. Not sure what you mean by alphabetical order.

From your site, under "How we find each photo's real date" section:

Sequence Neighboring photos

Photos scanned in alphabetical order often belong together, so nearby files can give useful context to each other.

The problem I have is that there's no way to embed an "uncertainty" into EXIF metadata in a standard way. I just want some photos to be "Summer 1987" or "February 1976" or even "1981-1983"... but I _have_ to invent some complete timestamp down to the second and then just rely upon captions or comments. But I generally know the dates far better than any AI could guess (based on ages of the individuals I know).

I worked on a family archiving product (which dead ended) and dealt with this problem. My hacked solution was to repurpose the seconds value to encode precision, as you generally don’t care about seconds. I forget the exact scheme, but it was something like this: 0=minute precision 1=hour 2=day 3=month 4=quarter/season 5=year 6=decade Also note that the ISO date standard allows you to drop any digits you aren’t sure…

The last one seems like it could also be problematic, how do you distinguish the 1960s decade from the literal year 196. In this case it’s kind of obvious since photography wasn’t very popular in the year 196.

Interesting question. From the Wikipedia article,

> ISO 8601 allows Gregorian dates from the introduction of the calendar on 15 October 1582.

My dad was a prolific family photographer when I was growing up (which I guess we all are now, with our phones). He also meticulously cataloged the photos and used a spreadsheet (first created on our Compaq Portable!) to store "metadata" about them, such as descriptions, dates, people in the photos, etc. A few years back, as family Christmas presents, my parents had the photos digitized, and had someone add the "metadata" as a caption on every photo.

This led to the first AI-related project I undertook that really blew my mind. I wrote a python script that read the captions, then sent them to ChatGPT with a prompt that asked it to get the exact coordinates of any locations mentioned, and to get dates for captions that mentioned a holiday or other even, but not a date, e.g.: "Christmas 1987," my birthday, which I included in the prompt, etc. I was then able to apply the results to the exif data the majority of the photos.

Now when I open Google Photos, my timeline stretches back to the day I was born, and the location heatmap shows the where photos were taken on extensive road tripping we did as a family.

I created a simple app of known family geo spots, and manually geo tagged all my family's photos (8000). Did the exact same thing and gave it to my parents as a Christmas gift. It's all in Immich and the map is amazing.

I'm trying to help others get this same experience of enjoying their photos they grew up with; it's so easy to find a picture of me when I was 4 years old to compare against my kid today.
