What the tool does to a face
One press does four things. It reads a neighbourhood around the point you pressed and builds a low-frequency copy of it. It walks two rings of candidate positions — forty-eight in all, at two and a bit and three and a bit brush-widths out — and scores each on two terms: how closely its tone matches the destination across sixteen probe points, and how much texture energy it carries of its own. It picks the lowest total. Then it writes the candidate’s texture over the destination’s tone, feathered by the hardness setting.
The second scoring term is the one that matters and the one most tools omit. A candidate patch that happens to match in tone but contains a pore cluster, a hair or the edge of a freckle will transplant that feature onto the place you just cleaned, and it will sit there looking exactly like what it is. Penalising a candidate’s own high-frequency energy is how the brush finds quiet skin rather than merely nearby skin.
Because the tone under the stroke is the destination’s own, the result carries no edge. That is not a blend being tuned — there is nothing to blend, because only the texture moved.
The order to work in
Blemishes before smoothing, always. A dark mark left in place when the skin layer runs does not disappear — the smoothing pass reads it as low-frequency tone and spreads it into a soft grey patch several times its original size, which is harder to remove than the spot was. The stack enforces the order internally, but the point stands for how you work: clean the discrete marks, then decide how much texture to take.
Zoom to 200 with the 2 key before you start and pan with a drag. Size the brush so the drawn ring clears the mark by a little. Press once per mark rather than scrubbing; each press is one scored transplant and repeating it in the same place stacks two of them. If a stroke lands badly, undo it and move the brush rather than healing over the heal.

What it will not do
- It cannot heal a mark that spans a feature edge. The sample ring has to sit on skin of roughly one tone. A blemish lying across a nostril, a lip border or the rim of a shadow gives the scorer nothing clean to find, and the honest move is two small strokes rather than one large one.
- It is not built to remove things from a background. A ring a few brush-widths across cannot reconstruct structure, so a doorframe or a shoulder behind the subject comes back smeared. That is a different algorithm and a different site.
- It keeps the sitting, not the session. A hundred and twenty undo steps and every stroke in the ledger last as long as the portrait is open. Reloading the page clears everything, because nothing here is written down anywhere.
