Adobe Camera Raw (ACR) is a core photo processing engine developed by Adobe Systems. It serves as the foundational development module for handling RAW image formats within Adobe Lightroom and as a filter plugin in Adobe Photoshop. ACR enables non-destructive editing, allowing photographers to adjust exposure, color correction, tonal range, and sharpness before committing changes to the final pixel data.
Core Functionality & Integration
ACR acts as the bridge between raw sensor data and standard image formats. Key capabilities include:
- Non-Destructive Editing: Adjustments are stored as metadata or sidecar files, preserving original image integrity.
- AI-Driven Masking: Utilizes machine learning for subject selection, depth range masking, and sky detection to isolate specific areas for targeted adjustments.
- Advanced Gradient Tools: Includes linear, radial, and brush-based gradients for precise local control over exposure, contrast, and color.
