Editing Digital Negative (section)

===Objectives===
The objectives of the DNG file format are:<ref name="adobe2004"/><ref name="DMDkevinconnor"/><ref name="DNGmain">Adobe: [https://www.adobe.com/products/dng/ Digital Negative (DNG) - The public, archival format for digital camera raw data]</ref><ref name="DNGintromanufacturers">Adobe: [https://www.adobe.com/products/dng/pdfs/DNG_primer_manufacturers.pdf Introducing the Digital Negative Specification: Information for manufacturers]</ref>
;Digital image preservation (sometimes known as "archiving")
: The [[US Library of Congress]] states that DNG is a recommended alternative to other raw image formats.<ref name="USLOCpreferences">Planning for US Library of Congress Collections: [http://www.digitalpreservation.gov/formats/content/still_preferences.shtml Preferences in Summary]</ref> The Digital Photography Best Practices and Workflow (dpBestflow) project, funded by the United States Library of Congress and run by the [[American Society of Media Photographers|American Society of Media Photographers (ASMP)]], singles out DNG, and states "DNG files have proven to be significantly more useful than the proprietary raw files in our workflow".<ref name="dpBestflowDNG">dpBestflow: [http://www.dpbestflow.org/node/305 Raw File Formats]</ref>
;Easy and/or comprehensive exploitation by software developers
: Software could support raw formats without DNG, by using [[reverse engineering]] and/or [[dcraw]]; but DNG makes it easier, and many software products can handle, via DNG, images from cameras that they have no specific knowledge of,<ref name="PEARSONnotnative">Barry Pearson: [http://www.barrypearson.co.uk/articles/dng/dng_not_native.htm Support via DNG but not native raws]</ref> however, any settings stored in the DNG file by software from one company are unlikely to be recognized by a product from a different company.
;In-camera use by camera manufacturers
: About 12 camera manufacturers have used DNG in-camera. About 38 camera models have used DNG.<ref name="PEARSONcameramakers">Barry Pearson: [http://www.barrypearson.co.uk/articles/dng/products_cameras.htm Products from Camera Manufacturers that support DNG in some way].</ref> Raw image formats for more than 230 camera models can be converted to DNG.<ref name="PEARSONhistory">Barry Pearson: [http://www.barrypearson.co.uk/articles/dng/history.htm A brief history of DNG]</ref>
; Multi-vendor interoperability
: Unlike the proprietary RAW formats used by most cameras, DNG is supported by multiple vendors, and is readable by a multitude of software applications.
