Files with an .SRW extension contains a raw image, captured with a Samsung digital camera sensor, stored in a reserved format. It is a RAW file – unlike a bitmap, it contains also additional information, such as white balance or exposure.

SRW files are usually processed – developed, before being printed out or published. Specific parameters of a photography can be adjusted with no quality loss while being saved multiple times before being exported into a more common format (like JPG for instance).
