dcraw - 9.28-2 main

This utility converts the native (RAW), format of various digital
cameras into netpbm portable pixmap (.ppm) or TIFF images. Supports
the following models: Canon, Kodak, Olympus, Nikon, Fuji, Minolta
and Sigma (see http://www.cybercom.net/~dcoffin/dcraw/ for full list)
Note: This utility does not read directly from the cameras, only
the files after they have been downloaded, use gphoto2 for that.
