Nikon RAW Image Format | Nikon | Camera Raw Files |
The NRW (Nikon Raw Image File) file extension is used by digital cameras manufactured by Nikon. It is a raw image format that stores uncompressed, lossless images and can be opened by the Nikon ViewNX software. The files are sometimes referred to as “NEF,” or Nikon Electronic Format Files. All current Nikon cameras are able to save raw image files as NRW; they also support and can save images in the .JPG or .TIFF formats.
Technical Details and Similar File Extensions
NRW files are large in size due to their high-quality, uncompressed nature. They can contain any type of image data including metadata, such as EXIF information like exposure settings. A single raw image can exceed 20 megabytes in size depending on the camera settings and resolution used to take the photo. As a result, are perfect for saving large images without losing details or key information like EXIF data.
Other similar file extensions include .ARW, .CR2, .DNG, .PEF, .RAF, and .RAW. Although these raw image formats differ widely between camera manufacturers, they can often open NRW images with compatible editing software. Some popular photo-editing programs such as Adobe Photoshop or Lightroom Classic can open and edit most of the various raw image formats.
Programs for WINDOWS system
Programs for MAC system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .NRW) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .NRW extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .NRW file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .NRW extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .NRW extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .NRW file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .NRW file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .NRW file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .NRW file) will be extended to the maximum.
It is also good to check
- if the .NRW file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
