Eye and sharpness assessments are assistance, not final decisions. Inspect the face or detail at a useful zoom and check the original photo. Low-contrast detail can be sharp without a focus-peaking highlight. Uncertain face results need your judgment.
Review uses a fixed queue: marking a photograph does not remove it from that queue. Browse filters are separate. If expected photos are missing, check the active filter, collapsed stacks, and Subfolders.
Keys depend on context. F enters Focus Mode in file Browse, while Photos browsing uses F for Favorite. A text field can also consume typing. Use ⌘K to find the action and read why it is unavailable. Review guide · Shortcut contexts.
