SpectraSortPicking vs culling

Photo picking vs photo culling.

They're two names for the same decision, approached from opposite ends. Culling is the photographer's word, and it means subtracting the failures. Picking is the everyday version, and it means surfacing the winners. The difference is worth understanding, because it tells you what kind of tool you need.

Culling: the subtractive tradition

Culling comes out of professional workflow, where a shoot produces 500 frames and the client gets 40. The work is subtractive: find and remove the failures, the soft focus and the closed eyes and the redundant takes, until what's left is the deliverable. Traditionally it happens on a desktop, in a rating tool, working through the shoot in order like a contact sheet.

Picking: the additive question

Picking starts from the other end and asks which photos, out of everything here, are worth keeping. It's the camera-roll version of the problem. There's no client and no deliverable, just a library to live with, and you don't need every failure removed. You need the winners surfaced, which makes it a ranking problem.

Where they converge

In practice the two are one loop, and SpectraSort runs it as one loop:

  1. Pick first: the slice comes back ranked by quality, your learned taste, or what you asked for. The surfacing half is done before you start.
  2. Cull second: swipe through the ranked review, right to pick, down to keep, left to let go. Duplicates, bursts and look-alikes come stacked, so each repeated moment is one decision.
  3. Finish: Batch Process files the picks to an album or the share sheet and clears the rest, through the system dialog.

If you're wondering which one you need, the usual answer is both halves, in that order. The culling workflow in detail → · The picking side →

FAQ

Picking & culling.

Is culling just deleting photos?
No. Culling is deciding, and deletion is an optional last step. A cull can end in an album of keepers with nothing deleted at all.
Do I need a culling tool if I'm not a photographer?
The camera roll is the largest unculled photo archive most people own. If your library has thousands of photos and repeated moments, you have a photographer's problem without the photographer's tooling. That's the situation these apps exist for.
What does AI actually do in culling?
Three things. It ranks frames before you look, so review starts at the top of the pile. It stacks near-identicals, so a burst is one decision. And in SpectraSort's case it learns your taste from your keeps and rejects, so the ranking gets personal over time.
Can one app do both?
That's how SpectraSort is built: rank first, swipe second, batch to finish. Five sorts a week are free, and $19.99 once removes the cap. No subscription.
