If you need RAW file support for your camera in GIMP, you can download UFRaw and install the plug-in. This plug-in supports Adobe Digital Negative, Canon, Nikon, Sony, Fuji, Olympus, Pentax and Minolta RAW file formats. The download, much like the software, is also free. It can also be ran both as a standalone feature or from within GIMP.
After installing the UFRaw, you just need to open a RAW file normally using File>Open or open a file directly with UFRaw. Because UFRaw can run as a standalone, it means you don’t have to open GIMP to see your RAW files.
As you can see, it’s quite straightforward. If you ever worked with RAW images in Adobe you will find some similarities. The feature offers a few interesting options including Curves, Levels, a noise reduction option, white balance and more. This is a tool that comes in handy for many amateur photographers.
