What is DNG?
DNG meaning in Digital terms is Digital Negative (DNG) is a digital image file format designed by Adobe Systems. DNG is a file format that wraps camera sensor data (“camera RAW data”) plus metadata to support image reconstruction, adjustment, and display based on the TIFF/EP standard. Thus it can be seen as a means to “normalize” a RAW image. Adobe has submitted the format to ISO in order to establish a standard format that can be used in place of the dozens of different proprietary RAW formats currently in use.
