When the batch route is the right instrument
The region solver works best when the photographs belong to one setup: a product, object or person separated from a reasonably consistent background. It does not download the optional person model, and it does not pretend that an automatic edge is final when the result comes back almost entirely opaque or transparent.
What the queue cannot judge
- Hair, glass, smoke and motion blur need an edge inspected against light and dark backings; use the guided tool for those files.
- A foreground that touches every edge can look like background to a border-seeded region solve.
- The batch route has no keep or erase brush. A row marked review should be opened individually before publication.
- Output is always PNG because JPG has no transparency channel.
Use the guided routes for difficult edges
- Cut out a product photoA narrow detail band for hard manufactured edges, plus manual keep and take-away brushes for handles and holes.
- Cut out hair and furA wider uncertain band and a softer ramp, set that way before you arrive.
- Remove a background with a modelA network trained on people proposes the edge instead of the colours in your photo. It is downloaded only when you ask for it, and the size is printed first.
- Make a picture transparentThe same four steps, with the file-format question answered on the way out.
