How do I fix a small mistake in an image?

Use Fix spots when an image is almost right but one area is wrong, for example a stone with the wrong colour or an extra prong.

1. Open the image (in Library, or while reviewing a batch press F).
2. Choose Fix spots.
3. Tap where something is wrong. Drag while placing to make the circle bigger or smaller. You can add up to 8 marks.
4. For each mark, say what to change (up to 200 characters). You can also add an overall note.
5. Leave Keep everything outside the marks on to protect the rest of the image.
6. Click Fix N areas (or Apply the change).

Your original image is never changed. The fix is saved as a new image. The cost (about one image at that size) shows before you apply it.
