The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPG is a commonly used method of lossy compression for digital images, particularly those produced by digital photography. The use of the file format is royalty-free.
DNG is based on the TIFF/EP standard format and mandates effective use of metadata.
Since the launch, all Adobe photo manipulation software (such as Adobe Photoshop and Adobe Lightroom) supports DNG. Digital Negative (DNG) is a patented, open lossless raw image format written by Adobe used for digital photography.
