Autostack (Beta)

Autostack is a batch tool: point it at a folder that contains several focus brackets and it splits them into separate stacks — grouping the images by capture time — then stacks each set automatically. It’s the fastest way to triage a card full of brackets and see which ones are keepers.

Beta. Autostack is still in beta. It handles the common case well (one folder, several brackets shot back-to-back), and we’re refining the grouping and options based on feedback.

Opening Autostack

Section titled “Opening Autostack”

From the menu bar, choose File → Autostack a Folder… (Beta). A setup window opens.

How it works

Section titled “How it works”
  1. Pick a source folder — the folder that holds your brackets. Autostack scans it and groups the images into focus-bracket sets by capture time: a run of frames shot close together becomes one stack; a gap in time starts the next.
  2. Choose where the results go — into a single “Autostack results” folder, or alongside each stack’s source frames.
  3. Confirm the plan — Autostack shows how many stacks it found, how many images they contain, and how many leftover frames didn’t fit a set, plus a disk-space check.
  4. Stack — each set is stacked at full resolution with the same unified engine as a manual stack. A progress view shows overall and per-stack progress with a running log, and you can cancel at any time.
  5. Review — when it’s done, open the results in the Library to pick your keepers.

Options

Section titled “Options”

The setup screen covers the common case with sensible defaults; an Advanced section exposes the rest:

  • Source images — copy them into each stack’s folder (originals kept) or move them.
  • Minimum images per stack — sets smaller than this are treated as leftovers rather than stacked.
  • Bracket gap — how long a pause between shots starts a new stack. Increase it if back-to-back brackets are being merged into one; decrease it if a single bracket is being split in two.

RAW+JPEG pairs of the same shot are treated as a single frame.
