Saving a DNG file
Next, you will save your image as a DNG i le. A DNG i le is essentially a digital
negative i le that maintains all the corrections you have made, in addition to the original
unprocessed Raw image.
Adobe created the DNG format to provide a standard for Raw i les. As mentioned
previously, camera vendors have their own proprietary Raw formats and their own
extensions and proprietary software to open and edit them. The DNG format was
developed to provide a standard maximum-resolution format that all camera vendors
would eventually support directly in their cameras. Right now, DNG provides you with
the opportunity to save your original Camera Raw i les in a format that you should be
able to open for many years to come. Note that you can reopen the DNG over and over
again, making additional changes without degrading the original image.

Click the Open Image button. The adjusted and cropped image is opened in

of the original Camera Raw i le—your DNG i le remains intact.
