This format is used for storing photos taken with Swedish Hasselblad cameras. It has a RAW image file structure. It is saved without applying automatic corrections. Photographers can edit the 3FR photos by changing the white balance, color correction, and other parameters without sacrificing image quality.
To decompress a DBK file outside Sony Ericsson PC Suite, the user should rename the file extension to .ZIP and open it with a .ZIP decompression utility. DBK files are also associated with FJ Software Development's MyPhoneExplorer, which can also be used to manage a Sony Ericsson mobile phone.
