Digital Negative Specification

by Jamie Nicholson

Unless you are a professional photographer and take alot of pictures that need further processing, then RAW file format might be relatively unknown to you.

A lot of professional photographers have been using the RAW file format for their images; this format gives them better creative control over the final outcome of the photo.
A Raw file format contains all the data of an image that the camera sensors capture before the camera processes the image. JPEG and TIFF formats have been processed by the camera according to the settings the user has specified.

Many high end DSLR’s have the option to shoot in RAW format. The only problem with RAW images is the format is different between many of the manufactures and there is no guarantee that you will be able to open the image. Photographers needed a way to store their RAW file formats for long term. With all the file formats out there and changing technology how can we be sure that they will still be around 10 years from now so that we can still view our photos.

In 2004 ADOBE created the Digital Negative Specification, the DNG file format. This standardized the RAW file format to be utilized across the board. They also launched a free DNG file software converter.
In 2007 this program was integrated into their Photoshop CS3, this streamlined productivity and Camera RAW enhancements. It recognizes many of the popular manufacture RAW images file formats for ease with conversion.
