Technical Details

FilmulsionLab uses industry-standard .cube LUT files for accurate film emulation. The application employs trilinear interpolation for smooth color transitions and precise mapping.

The image processing pipeline is built with HTML5 Canvas API for high-performance client-side image manipulation. The application architecture follows a modular design pattern with separate modules for:

• LUT parsing and validation
• Image data manipulation
• User interface handling
• File I/O operations

The frontend is built with vanilla JavaScript for optimal performance without external dependencies. The responsive design uses CSS3 Flexbox and Grid layouts for consistent experience across devices.

No cookies or tracking scripts are used. All processing is done locally in the browser using the FileReader API and Blob objects for efficient memory management.
