Convert DNG to J2K

The Digital Negative (DNG) file extension, developed by Adobe Systems and introduced in 2004, is an open, lossless raw image format designed for digital photography. DNG aims to provide a standardized format for raw files, ensuring compatibility across various software and hardware platforms. It is based on the TIFF/EP standard and incorporates extensive metadata, making it suitable for long-term archival purposes. DNG files are widely supported by numerous camera manufacturers and software applications, facilitating efficient storage, sharing, and editing of high-quality images.

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.
