Description
A lossy DNG is a Digital Negative raw photo whose image data is compressed with lossy JPEG, making it much smaller than a standard lossless DNG.
The JPEG 2000 Code Stream (j2c) file format is a type of image file format that is part of the JPEG 2000 family of image standards. This format is specifically designed for encoding images in a highly efficient manner, allowing for both lossless (exact reproduction) and lossy (approximate) compression. The j2c format focuses on the core coding stream of JPEG 2000 images, representing the encoded image data without additional metadata or structure.
