Selection Proof turns picked photos into a saved selection project. Mark Keep, Maybe or Drop, add captions and deliver a PDF proof with a complete decision CSV. HOW TO USE THE UPGRADE 1. Add photos through the system picker and name the project. Tap each preview to set its decision, caption or order. 2. Choose paper size, columns and rows. Optionally include keepers only in the PDF. 3. Save the project, build and inspect the PDF, then share it with the CSV. Reopen saved projects to continue. Contact-sheet PDF export now uses a saved project workspace, with paper and grid layout controls. Originals in Photos are not edited or deleted. WHAT TO KNOW Up to 100 photos per project and 20 saved projects, within bounded storage limits. Stored previews are resized to at most 1200 pixels and are not original-resolution deliverables. The PDF can shorten captions in small cells; the CSV keeps full captions and every photo’s decision. Keep-only proofs retain project numbers, so gaps are expected. Fingerprints identify the resized preview, not the original Photos asset. iPhone and iPad. No account required.
