An RW2 file is a raw image file format, specifically a camera RAW file created by a Panasonic digital camera like the LX3 or LX5.

This type of file has a RAW raster image just as it was captured by the camera’s sensor, and you can edit it to adjust color, exposure, and other properties, by using an image or photo editor.

The RW2 file, like other raw image formats, stores uncompressed image data from the sensor, and the file is both print and view ready.

Photographers are at an advantage as they get to decide how to use and/or develop the images via a special program, but the access to the raw data also gives them the flexibility of deciding how to use the images and how to process them, or completely alter the image altogether.

2. RawTherapee

This is a cross-platform program for processing RAW images or photos, and comes with tools that deliver high quality and efficient development of the images.

The program is a free and open-source software written in C++ and uses a patched version of dcraw to read the RAW files. This tool gives you advanced control over the demosaicing and developing process, with a subset of image editing features focused on improving your workflow by handling volumes of images.

It uses a non-destructive editing concept for post-production of photos, and the edits or adjustments are reflected in the preview image instantly, though not applied on the opened image in the actual sense, as this happens during the export process.

This software supports most raw formats and non-RAW image formats like PNG, TIFF and JPEG, plus raw DNG images. You can tweak photos, use the color histogram, make adjustments and revert changes at any time, plus use its many photo opening and processing features.
