Julieanne Kost talks about Adobe’s Lightroom Classic 15.4 update that introduces a suite of AI-driven enhancements designed to streamline photographic workflows and improve editing precision.
She highlights key elements in the release, discussing refined masking capabilities and assisted culling tools that use intelligent scoring to evaluate subject focus and facial expressions. The software now includes a robust duplicate detection system and bidirectional keyword syncing across desktop and mobile platforms to simplify large-scale asset management. Performance is significantly boosted through Apple Neural Engine support for noise reduction and increased brush tool responsiveness for smoother editing. Additionally, the update expands metadata filtering for AI edits and adopts a universal protocol to provide enhanced tethered capture for Canon cameras.

Overall, these updates focus on integrating advanced automation with hardware-specific optimisations to create a more efficient user experience. Lightroom Classic 15.4 replaces manual labor with silicon-level optimization. These updates redefine the professional photo workflow via high-end automation.
- Precision Subject Masking: AI accurately maps complex edges like cacti. This eliminates manual cleanup in targeted edits.
- Assisted Culling: Face-specific scores evaluate eye sharpness and openness. Pros can now identify peak expressions instantly.
- Local Duplicate Detection: The system stacks images via visual data, ignoring filenames. This automates duplicate detection and catalog organization.
- Apple Neural Engine for Denoise: Re-enabled ANE support accelerates Denoise on Apple Silicon. Users gain massive hardware-level speed boosts.
- Responsive Brush Performance: Backend optimizations eliminate latency during large-scale AI masking. This ensures smooth, lag-free editing on high-resolution canvases.
- AI Metadata Filtering: Filter catalogs by Generative AI status or update needs. This simplifies managing complex, AI-augmented libraries.
- Bidirectional Keyword Syncing: Keywords now sync across mobile, web, and desktop. The “pipe” character preserves complex hierarchies cross-platform.
- PTP Canon Tethering: New PTP-based protocols ensure future-proofed connectivity. This enables immediate compatibility for PTP-compliant Canon bodies.
