Convert CUBE to J2K

A CUBE file (short for Color Lookup Utility Table) is a 3D Lookup Table used in Luminar software for color grading and photo editing. It allows photographers to remap colors and adjust tones efficiently. Introduced in Luminar 2018, CUBE files enable users to apply complex color adjustments with a single click, enhancing workflow and creative flexibility. The format is also compatible with other editing software like DaVinci Resolve.

The J2K file extension stands for JPEG 2000 Code Stream Syntax, a part of the JPEG 2000 standard developed by the Joint Photographic Experts Group (JPEG). Introduced in 2000, JPEG 2000 offers superior image compression and quality compared to the original JPEG format. The J2K codestream is highly flexible, supporting both lossy and lossless compression, and allows for scalable decoding, which means images can be efficiently accessed at various resolutions and quality levels. This makes J2K ideal for applications requiring high-quality image storage and transmission, such as medical imaging, digital cinema, and satellite imagery.
