Lightroom Classic 15.4: Sharper Masks, Smarter Duplicates, and Faster Denoise
Lightroom Classic 15.4 adds three notable upgrades: a revamped Select Object (now v5) that significantly improves masking accuracy, a catalog-wide duplicate detection tool to flag and remove duplicates, and a 50% faster AI denoise on Apple Silicon Macs. The update process zips and saves the old catalog before upgrading, and a video demo shows tests across diverse images, while noting a few interface quirks to watch for in the duplicate workflow.
