RW2 is a RAW image format used by Panasonic digital cameras. RAW image files contain minimally processed data from the image sensor of a digital camera. This means that RW2 files retain a much higher level of detail and dynamic range compared to processed image formats like JPEG. Photographers often prefer RAW formats like RW2 because they offer greater flexibility in post-processing, allowing them to adjust parameters such as white balance, exposure, and contrast without significantly degrading the image quality. RW2 files are uncompressed or losslessly compressed, preserving all the original image data captured by the camera. This makes them ideal for professional photography and situations where image quality is paramount. However, RW2 files are typically larger than JPEG files and require specialized software for viewing and editing. The specific metadata stored within the RW2 file can include camera settings, lens information, and other relevant data about the image capture process. Because it is a proprietary format, support for RW2 files can vary across different software applications, although most major image editing programs now offer compatibility.
