A file that has a DNG extension is basically a negative raw image file written by Adobe for the purpose of digital photography. The extension was launched back on 27th September, year 2004. The launch comprised of the very first version of the DNG extension, along with several other products including a utility to convert the DNG files free of charge. All the Adobe photo manipulation applications such as Adobe Lightroom and Adobe Photoshop support the DNG file extension.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .DNG file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .DNG file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .DNG file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
There may be several reasons why you cannot open the file with .DNG extension. Directly on this website you can find a solution of the most common problem with the .DNG file – that you do not have on your computer the appropriate program to open the file.
