OS-specific troubleshooting

What is a .RW2 file?

RW2 files are unprocessed images captured by Panasonic cameras, storing data directly from the camera's sensor. They offer greater flexibility for post-processing compared to JPEGs.

Background

The RW2 format is used primarily by Panasonic's Lumix series cameras. As a RAW format, it retains all the data captured by the camera's sensor, allowing photographers to adjust exposure, white balance, and other settings after the photo is taken. Unlike JPEGs, which compress image data, RW2 files provide higher quality and more detail, making them popular among professional photographers. However, due to their large file size and need for specialized software, they are less convenient for casual users. RW2 files are similar to other RAW formats like Canon's CR2 or Nikon's NEF, but are specific to Panasonic cameras.
