What is X3F file?
The X3F (.X3F) file is a proprietary image file format developed specifically for the SIGMA cameras and used to store Camera RAW data. X3F files contain all aspects of the digital photo captured by the camera, including EXIF meta data, original bitmap data, as well as other details regarding the photographic conditions. X3F files are highly efficient in their use of storage space, and most photos are stored in less than 1MB on disk. [ ⏩ ] X3F file extension
What is DNG file?
File extensions put in item, for separated file extensions use the pipe symbol | . DNG, short for Digital Negative, is an image format developed by Adobe that was designed to act as a public standard for digital cameras. It is a container file format that stores raw image data, metadata, and thumbnail previews that are associated with the photographic image. [ ⏩ ] DNG file extension
Software, that you can use to convert
How to convert the file from X3F to DNG?
To successfully convert the X3F file to DNG, you should install one of the applications from the list. After installing the software, open the program and select the file you want to convert (file-name.X3F). The next step is to select the target format from the list, in this case DNG (usually converters allow you to convert to several different formats, so check out their features - maybe one of the available formats will suit you more than DNG).
What is a file conversion?
A data conversion is normally an automated process to some extent. The effect of the operation of one program is automatically the input product of another application. If that does not happen we need to help the process a little bit and convert the file on our own, e.g. X3F to DNG. To obtain a matched structure of the data, it is necessary to use an appropriate converter.
Program for converting X3F files to DNG files is a kind of a "binary code translator" compensating for the differences in the code or translating it in such a way so that another application could use it. For us, as users, the visible change will be only another file extension. (After converting the file, it will be the extension DNG, while before this step we had the X3F file). For the programs, the difference is on a much higher level – either the application will be able to open a new DNG file, or not.
