I have four photo libraries. Sometimes five, depending on how I count.
One for family. One for a long-running personal documentary project. One for commercial work. One for the apps — product shots, reference images, screenshots I'll never ship. The fifth, if it counts, is a scratch drive of things I shot for fun and haven't decided what to do with.
In Lightroom, each had its own catalog. Different keyword hierarchies, different collection structures, different rating conventions, because I reasoned about the work differently in each context. The separation was load-bearing. Family photos aren't commercial assets. A documentary edit shouldn't drift into the screenshot folder.
What the catalog gave me
The Lightroom catalog is, among other things, a browsing engine. Filters, smart collections, keyword cascades — all of it reads off a fat index that knows more about my photos than I do. On a good day, with disciplined metadata, I could pull up "portraits, five-star, 2019, outdoor, Oslo" and get a sensible answer in seconds.
On a less good day — which is most days, because metadata discipline is a thing you lose quickly — I'd type two words, get 12,000 results, and scroll until I gave up. The catalog was only as sharp as my keywording, and my keywording has decades of gaps.
What Photo Archive gives me instead
Photo Archive doesn't have a catalog. Just folders and XMP. Point it at disks, it reads what's there, and the files are the truth. There's no lock-in, but there's also no fat index to mine.
Photo Archive Pro adds one — it functions, practically, as a catalog — but the index is honest about what it is: a map of folders, sequential by capture date or filename, filterable if you've done the metadata work. Smart albums are there. So are cascading filters. They work well. They also depend on the same keyword discipline I've been quietly failing at for twenty years.
So the honest picture of how I browse my archive, most days, is this: I open the app, I see the last thing I shot, I scroll a little, I close the app. Out of somewhere north of a hundred thousand photos, I look at maybe a hundred in a given month.
On This Day
A few weeks ago I started using a different access pattern: the date, stripped of everything else.
On This Day does what the name says. It shows me every photo taken on today's calendar date, across every year in the archive. April 22, 2011. April 22, 2016. April 22, yesterday. Twelve frames from a trip I'd half-forgotten. A portrait of someone I haven't spoken to in six years. A product shot from an app I never shipped.
Nothing is curated. Nothing is algorithmic. There's no "featured memories" carousel trying to guess what will make me linger. It's just the date, applied as a filter across the whole archive, and whatever falls out falls out.
The effect has been quietly surprising. Photos I took and never touched again turn out to be, occasionally, the best thing I shot that year. Photos I thought I remembered turn out to look nothing like the memory. Sessions I was sure I'd edited turn out to contain frames I never saw.
Surprise Me
The companion mode is blunter. One photo, full-screen, from anywhere in the archive, chosen at random. Arrow key for the next one. No date, no folder, no rating filter. Just: here is a photograph you made. Look at it.
I didn't expect to like this as much as I do. Random doesn't sound like a feature. But when the alternative is the same folder you always open, random is generous. It gives you back the parts of your own work you stopped visiting.
What it doesn't do
This isn't a workflow. It isn't search. It isn't going to replace the filter stack in Photo Archive Pro, and it isn't going to save me from the keywording I've been avoiding. If I need a specific photo for a specific reason, I still open the catalog — the index is still the right tool for that job.
What this is, is a different verb. Not find. Not organize. Just see — with the small constraint of a date or a coin flip doing the selection you can't be bothered to do yourself.
Why it works
I think the reason it works is that most of my metadata is the date. Capture time is EXIF; it's on every file, accurate, cheap to read, and it doesn't depend on me having been diligent. The photos I never keyworded still have April 22 stamped on them. The dateline is the one index I never had to maintain.
Everything else — keywords, ratings, stars, picks, collections, smart albums — is aspirational. The date is factual. Browsing by the factual part of the metadata turns out to reach corners of the archive the aspirational part never indexed.
Year over year, the same calendar day becomes a kind of slow time-lapse of your own life and practice. You notice the shift in gear. The shift in subject. The shift in whatever it is that you've been, without really noticing, getting better or worse at.
Photo Flashbacks is the app that does this — On This Day and Surprise Me, pointed at your folders on disk. Part of the Photo Suite.
