Shortcut: Ctrl+Shift+M / Cmd+Shift+M
How to mask:
Intersect / Subtract (NEW) – combine masks (e.g., Subject minus Eyes).
Copy/Paste masks between photos (NEW) – right-click mask → Copy, then paste in another image.
Adjustments within a mask:
Example: Mask a face → reduce Texture/Clarity slightly for skin softening, increase Exposure slightly for brightening without affecting background.
The dreaded "Sync stuck at 43%" error has largely been exterminated. The new sync engine in 12.3 uses less bandwidth and recovers from network drops without requiring a database reset.
If 12.3 breaks your workflow:
While the changelog was extensive, three major pillars define Lightroom Classic 12.3.
Lightroom Classic 12.3 serves as a perfect example of an "under-the-hood" update. While it lacks the marketing sizzle of features like "Denoise AI" (which arrived in later versions), it laid the groundwork for those tools to function correctly.
For photographers, the move to Scene-referred color was a statement from Adobe: they are listening. By fixing the long-standing color consistency issues, version 12.3 made Lightroom a more trustworthy tool for professionals who demand precision. If you had previously hesitated to update due to workflow disruption, 12.3 was the release that solidified stability and color accuracy for the modern era.
Is it worth updating? If you are on an older version of Lightroom Classic, jumping to 12.3 (or newer) is highly recommended simply for the color consistency improvements. It changes the way you see your edits, ensuring your final output matches your creative vision.
Adobe Lightroom Classic 12.3, released in April 2023, is a landmark update that fundamentally changes how photographers handle high-ISO noise and localized adjustments. Often referred to as "more than just a point upgrade," this version introduces powerful AI tools that bridge the gap between Lightroom and high-end third-party plugins. The "Game Changer": AI-Powered Denoise
The most significant addition in version 12.3 is the AI Denoise feature, which utilizes machine learning to remove digital noise while preserving intricate details that traditional manual sliders often smear.
How it Works: Located in the Detail panel, the "Denoise" button opens a dialog with a single intensity slider. Adobe’s goal was to deliver usable results for 20MP full-frame sensors at ISOs as high as 51200.
Workflow Integration: When applied, Lightroom creates a new, enhanced DNG file (marked with "-Enhanced-NR" in the filename). This allows you to retain the original RAW data while working on a cleaner version of the file.
Current Limitations: In this version, AI Denoise is restricted to Bayer and X-Trans RAW files. It cannot be used simultaneously with Super Resolution or on existing DNG merges like panoramas.
Adobe Lightroom Classic version 12.3, released on April 18, 2023, introduced significant AI-driven features and workflow enhancements, most notably a ground-up redesign of noise reduction technology. Key Feature: AI Denoise
The flagship update in 12.3 was AI Denoise, an AI-powered tool designed to remove noise from RAW files while preserving fine detail better than previous manual sliders. Adobe Lightroom Classic 12.3
Mechanism: Unlike traditional luminance sliders that often "smear" details or create a plasticky look, the AI algorithm distinguishes between noise and structural details like feathers or skin texture.
Workflow: Users can apply it via the Detail panel. It creates a new Enhanced DNG file, leaving the original RAW file untouched.
Performance: On mid-range hardware (e.g., GTX 1060), denoising a single high-resolution image takes approximately 60 to 70 seconds.
Best Practices: Expert tests suggest a "sweet spot" setting between 40 and 60 for the best balance of cleanliness and sharpness. Additional Enhancements
Masking Improvements: New AI categories for masking people allow for precise, automatic selection of facial hair and clothing.
Tone Curve in Masking: Support was added for using the Curve tool within local masking, providing much finer control over contrast and color in specific parts of an image.
Edit Indicators: The interface now provides a quick visual indication of which specific tools (e.g., Crop, Healing, Masking) have been used on an image.
Workflow Tools: Support for opening photos as Smart Object Layers in Photoshop was streamlined. Device and Lens Support
The update added support for several new cameras and lenses, including models from Sigma and Sony.
