PuerhLab is an innovative open-source solution for RAW photo processing and digital asset management (DAM). This software is tailored for photographers seeking a lightweight yet powerful tool that offers a highly compatible workflow for photo editing and library management.

Key Features

High-Performance Processing

CUDA-Accelerated Workflow: Benefit from real-time previews running at 60 FPS on modern GPUs, even with large RAW files (e.g., 45MP).
Efficient Memory Management: Optimized memory usage allows smooth browsing of libraries, with average DRAM usage around 767MB for a collection of 786 42MP RAW files.
Modern C++20: Built with a focus on modularity and maintainability, ensuring high code quality.

Professional Imaging Pipeline

Floating-Point Processing: Provides a 32-bit processing pipeline for advanced image adjustments.
Creative Color Grading: Supports CUBE LUTs for enhanced color grading capabilities.
Unlimited Edit History: Features a Git-like version control system that maintains an unlimited history stack with easy branching.
Rich Format Support: Output options include JPEG, TIFF, PNG, and EXR, all with metadata write-back capabilities.

Asset Management System

"Sleeve" System: A flexible inode-like file system using DuckDB for managing original RAW files and associated metadata in a unified structure.
Project Management: Easy sharing and backup of projects through a single project file containing all metadata, removing concerns over missing files or broken links.
Advanced Search Features: Includes filtering based on EXIF metadata, with plans to integrate semantic search and AI-assisted tagging in the future.

User Interface and Experience

PuerhLab features a modern user interface designed for ease of use, enhancing the overall user experience during photo editing and management tasks. Early demos illustrate its focus on a streamlined workflow and advanced adjustment controls, making it accessible to photographers of all levels.

System Requirements

Operating System: Windows 10/11 x64 (Linux and macOS support is planned).
Hardware: NVIDIA GPU with CUDA support (minimum compute capability 6.0), at least 8GB RAM (16GB recommended), and 500MB of disk space.

Conclusion

PuerhLab aims to provide photographers with a practical alternative for RAW file handling, offering a blend of performance, flexibility, and extensive features within a user-friendly interface. With continuous updates and additional features planned, it represents a promising tool in the landscape of digital asset management.
