Have you encountered a problem with a RAW file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a RAW file here. In the further part of this page we have added a list of programs that should open your RAW file. It is enough you choose a proper application for your operating system, download and install it.

Description

RAW files contain RAW image data generated by different models of digital cameras from different manufacturers, such as Panasonic, Leica and Casio.

The RAW files contain the unprocessed or minimally processed RAW data of the image sensor. Although these RAW (raw) data are larger than the JPEG files stored by the device, they are more versatile.

These sometimes called "digital negative" RAW data are excellent for post-processing such as the adjustment of the colors, correction of the exposure, suitable for sharpening or noise filter. They are indispensable for professional work or things like astrophotography.

In order to convert them into an RGB image format that can be commonly used, the data must be "developed". This means that processing steps such as interpolation and exposure as well as converting to a format such as PNG, PSD, TIFF or JPEG must be performed.

However, there is no uniform RAW data format. Every manufacturer has developed his own. These proprietary and often undocumented formats can only be processed by specialized software. They can contain different data, for example in different color depths, depending on the capabilities of the sensor as well as the software integrated in the camera. Manufacturers are changing their RAW formats relatively frequently, which means that program support often needs to be adjusted. Supporting the extension is not enough if the specific camera is not supported.

Most RAW files also contain metadata with information about the image and the recording conditions, in part also in the EXIF or IPTC standard.

Adobe Photoshop and Photoshop Elements support a large number of cameras with the help of the free plug-in Adobe Camera RAW (ACR). Which depends on the ACR version. However, newer versions of ACR can only be used by the latest versions of the main programs.

Programs which can open a RAW file

How to open a RAW file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the RAW file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a RAW file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support RAW files. At this point we are looking for disk space where the application was installed in and we can link it with a RAW file. Since then, our operating system will use the selected program to support all RAW files.

Other issues

Despite the described problem with RAW there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the RAW file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the RAW file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
