JPG, RAW and . . . DNG??
Adobe is introducing a public format for RAW digital camera files — DNG — Digital Negative Specification. Most professional photographers save their photos using the RAW format. This format is specific to each type of camera, so it causes problems for software developers that provide software that manipulates images.
The DNG format is based on the TIFF EP format, which is already used as the basis for many RAW formats. Specific metadata is required in this format, but also allows camera manufacturers to add their own.
Adobe is providing a free software tool that converts most RAW files to DNG.
