dcraw-m

Modified Decoder for RAW files from digital cameras

dcraw is an ANSI C program that decodes any raw image from any digital camera on any computer running any operating system. It's become a standard tool within and without the Open Source world. It's small (about 3000 lines), portable (standard C libraries only), free (both "gratis" and "libre"), and when used skillfully, produces better-quality output than the tools provided by the camera vendor. This version is modified to add auto-rotate to exported thumbnails, and also add adjustment for camera timezone offset. If your thumbnails appear upside down, set DCRAW_RTC env var.
