Adobe has released version 1.4 of its Digital NeGative (DNG) specification. The industry-standard raw format has been expanded to include 1) a new lossy compression option, 2) a Default User Crop tag that allows the in-camera crop setting to be respected while enabling the photographer to “un-crop” the image, 3) new floating-point information storage that allows for a larger amount of dynamic range to be stored within a file, and 4) a Transparency option for “undefined” pixels around the edges of a panoramic image stitched in-camera.
