Pix42
Use Pix42 before or beside Lightroom
Many photographers need a quick pass before importing, syncing, or editing a full shoot. Pix42 opens the original folder, lets you rate and reject images, inspect metadata, compare frames, and review capture-day groups without moving files into a managed catalog first.
Pix42 can also read Lightroom XMP sidecar crop and rotation for RAW preview workflows in Pro, which makes it useful beside an existing Lightroom-based process.
Clear boundaries
Pix42 focuses on viewing, culling, metadata, batch tools, map workflows, and non-destructive lightweight adjustments. If you need a complete raw development suite, Pix42 is best used as a fast companion rather than as a full replacement.
Pix42 includes this feature together with fast browsing, persistent ratings, duplicate detection, metadata tools, and batch conversion.
Try a lighter culling workflow.
Open a folder directly and decide what is worth keeping.
