RW2 is a RAW image format used by such Panasonic cameras as LX5 and LX7. Although, photos stored in the format cannot be printed right away, they are perfect for professional photographers because they are stored without pre-processing, which allows customizing the image settings in a video editor according to your needs. However, not many programs can open RW2 so the best way is to convert it to a more popular image format.

This is a color system for displaying image and video files. The luminance component (Y) in UYVY is digitized at each point, whereas the color difference components (U, V) are digitized two times less frequently. It has a 16 bits/pixel structure, and it is used in video rendering and image editors.
