Contains an enhanced `rpi2dng', which converts Raspberry Pi's RAW+JPG image (generated by `raspistill --raw`) to standard DNG. This enhanced version generates DNG files that work with `darktable', have the correct `AsShotNeutral' values (white balance), and do not contain the empty thumbnail. It will also copy EXIF tags, so you do not have to run `exiftool' manually. However, due to limitations in `libTIFF', rationals are expressed with large numerators and denominators, which will cause problems in some programs. `tiffinfo' and `exiftool' can extract the information correctly. Requires `libtiff5-dev' and `libexif-dev' to build. Does not need patched `libTIFF' anymore. NOTE: for IMX219 there might be serious lens color shading. Use `darktable`'s color correction and mask system to get rid of it. See also schoolpost/pydng and 6by9/raspiraw.
