Convert J2K to EXR

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.

The EXR file extension stands for OpenEXR, a high dynamic range (HDR) image file format developed by Industrial Light & Magic (ILM) in 1999 for visual effects and film production. OpenEXR is widely used for its ability to store multi-channel, floating-point images, supporting complex visual effects workflows with superior image quality and precision. Its features include lossless and lossy compression, arbitrary image channels, and a flexible data structure, making it an essential tool in professional digital imaging and animation industries.
