NAME

       UFRaw - Convert camera RAW images to standard image files.

SYNOPSIS

       ufraw [OPTIONS] <rawfile(s)>
       ufraw-batch [OPTIONS] <rawfile(s)>

DESCRIPTION

       The Unidentified Flying Raw (UFRaw) is a utility to read and manipulate raw images from
       digital cameras. It reads raw images using Dave Coffin's raw conversion utility - DCRaw.
       UFRaw supports basic color management using Little CMS, allowing the user to apply color
       profiles. For Nikon users UFRaw has the advantage that it can read the camera's tone
       curves.  Even if you don't own a Nikon, you can still apply a Nikon curve to your images.

       By default 'ufraw' displays a preview window for each raw image allowing the user to tweak
       the image parameters before saving. If no raw images are given at the command line, UFRaw
       will display a file chooser dialog.  To process the images with no questions asked (and no
       preview) use the command 'ufraw-batch'.

       The input files can be either raw images or UFRaw ID-files.  ID-files contain a raw image
       filename and the parameters for handling the image.

       UFRaw can also work as a GIMP plug-in. To activate it simply open a raw image or a UFRaw
       ID-file in the GIMP.

OPTIONS

       The options supplied on the command-line decide the starting-values for the GUI. The GUI
       will then allow you to tweak these values before saving the final image.

   General Options
       --version
           Display the version of UFRaw and exit.

       --help
           Display a brief description of how to use UFRaw and exit.

       --silent
           Do not display any messages during batch conversion.

       --conf=<ID-filename>
           Load all parameters from an ID-file. This feature can be used to tweak the parameters
           for one file using the GUI and using those parameters as the starting point for other
           images as well.

   Image Manipulation Options
       These command-line options override settings from the default configuration of UFRaw and
       from any loaded ID-file. The best way to learn about how these parameters work is to
       experiment with the GUI. All parameters correspond exactly to a setting available in the
       GUI. Not all parameters in the GUI have corresponding command-line options.

       --wb=camera|auto
           White balance setting. "camera" means that UFRaw tries to read the color-temperature
           and green color component that the camera recorded in the meta-information in the raw-
           file. This does not work for all cameras. If UFRaw fails to read the white-balance
           information from the meta-information, it falls back to "auto".

           "auto" means that UFRaw calculates the color-temperature and green color component
           automatically from the image data.

           The white-balance can also be set manually with the --temperature and --green options.

       --temperature=TEMP
           Manually set the color temperature in Kelvin (2000 - 7000).

       --green=GREEN
           Green color component. Range 0.20 to 2.50.

       --gamma=GAMMA
           Gamma adjustment of the base curve. Range 0.10 to 1.00. Default 0.45.

       --linearity=LINEARITY
           Linearity of the base curve. Range 0.00 to 1.00. Default 0.10.

       --exposure=auto|EXPOSURE
           Auto exposure or exposure correction in EV. Range -3.00 to 3.00. Default 0.

       --restore=clip|lch|hsv
           Control how highlights are restored when applying negative EV.  'clip' restores
           nothing and is therefore safe from any artifacts.  'lch' restores in LCH space,
           resulting in restored highlights with soft details (good for clouds).  'hsv' restores
           in HSV space, resulting in restored highlights with sharp details.  The default is
           'lch'.

       --clip=digital|film
           Control how highlights are clipped when applying positive EV.  'digital' corresponds
           to using a linear response, emulating the harsh behaviour of the digital sensor.
           'film' emulate the soft film response.  The default is 'digital'.

       --saturation=SAT
           Adjust the color saturation. Range 0.00 to 3.00. Default 1.0, use 0 for black & white
           output.

       --wavelet-denoising-threshold=THRESHOLD
           Wavelet denoising threshold (default 0.0).

       --base-curve=manual|linear|custom|camera|CURVE
           Type of tone curve to use. The base curve is a combination of the gamma curve
           corrected by the curve specified here.  The base curve is applied to each channel of
           the raw data after the white balance and color matrix, but before the ICC
           transformation.

           "manual" means that a manual tone curve is used.  This is probably not very useful as
           a command-line option, since there is no way to specify what the curve should look
           like.

           "linear" means that no tone curve corrections is performed.

           "custom" means that UFRaw shall use the curve supplied by the camera in the meta-
           information in the raw-file.

           "camera" means that UFRaw shall use the "custom" curve only if the camera was set to
           use it (according to the meta-information).  Otherwise the "linear" curve is used.

           CURVE can be the filename (without path) of any curve that was previously loaded in
           the GUI.

           The default is "camera" if such a curve exists, linear otherwise.

       --base-curve-file=<curve-file>
           Load the base curve from a file.  The curve file format can be either UFRaw's XML
           format or Nikon's NTC/NCV format.

       --curve=manual|linear|CURVE
           Type of luminosity curve to use. This curve is applied in HSV space and therefore hue
           and saturation should not be effected by it.

           "manual" means that a manual luminosity curve is used.  This is probably not very
           useful as a command-line option, since there is no way to specify what the curve
           should look like.

           "linear" means that no luminosity correction is performed.

           CURVE can be the filename (without path) of any curve that was previously loaded in
           the GUI.

           The default is "linear".

       --curve-file=<curve-file>
           Load the luminosity curve from a file.  The curve file format can be either UFRaw's
           XML format or Nikon's NTC/NCV format.

       --black-point=auto|BLACK
           Black-point value. Range 0.0 to 1.0, default 0.0.

       --interpolation=ahd|vng|four-color|ppg|bilinear
           Interpolation algorithm to use when converting from the Bayer-pattern to normal RGB
           values. AHD (Adaptive Homogeneity Directed) interpolation is the best, but also the
           slowest. VNG (Variable Number Gradients) is second best and a bit faster. Bilinear is
           the simplest yet fastest interpolation.

           "four-color" is a variation of the VNG interpolation that should only be used if you
           see strange square patterns in the VNG interpolation, See
           <http://www.cybercom.net/~dcoffin/dcraw/>.

           AHD is the default interpolation.  AHD interpolation is not supported for cameras with
           four color filters, such as the Sony-828 RGBE filter. In such cases, VNG interpolation
           will be used instead.

       --color-smoothing
           Apply color smoothing.

       --grayscale=none|lightness|luminance|value|mixer
           Grayscale conversion algorithm to use (default none).

       --darkframe=FILE
           Use FILE for raw darkframe subtraction.

   Output Options
       The options which are related to the final output are:

       --shrink=FACTOR
           Shrink the image by FACTOR (default 1).

       --size=SIZE
           Downsize max(height,width) to SIZE.

       --rotate=camera|ANGLE|no
           Rotate image to camera's setting, by ANGLE degrees clockwise, or do not rotate the
           image (default camera)

       --crop-(left|right|top|bottom)=PIXELS
           Crop the output to the given pixel range, relative to the raw image after rotation but
           before any scaling.

       --out-type=ppm|tiff|tif|png|jpeg|jpg|fits
           Output file-format to use.  The default output file-format is ppm.

       --out-depth=8|16
           Output bit depth per channel.  ppm, tiff, png and fits output formats can uses either
           8 bits or 16 bits to encode each of the  Red, Green and Blue components of each pixel.
           The jpeg format only allows for 8 bits for each color component.

           The raw-files contain more than eight bits of information for each color component.
           This means that by using an eight bit format, you are actually discarding some of the
           information supplied by the camera. This is not a problem if you only plan to view the
           image on screen. For prints you should consider a 16 bits workflow.

       --compression=VALUE
           JPEG quality factor. Range 0-100 with a higher number giving a higher quality at the
           cost of a larger file. Default 85. The --compression parameter is only relevant if the
           output file-format is jpeg.

       --[no]exif
           Embed exif in output. Default embed exif. Exif is currently embedded in JPEG, PNG and
           TIFF output.

       --[no]zip
           Enable [disable] TIFF zip compression. The zip-compression is loss-less.  Default
           nozip. The --zip parameter is only relevant if the output file-format if tiff8 or
           tiff16.

       --out-path=PATH
           PATH for output file. In batch mode by default, output-files are placed in the same
           directory as the input-files. In interactive mode UFRaw tries to ''guess'' if you have
           a favorite output directory.

       --output=FILE
           Output file name to use. This is only relevant if a single raw-file is supplied on the
           command-line. . Use '-' to output to stdout. The default is to name the output-file
           the same as the input-file but with the extension given by the output file-format.

       --overwrite
           Overwrite existing files without asking. Default is to ask before deleting an existing
           file.

       --create-id=no|also|only
           Control whether UFRaw ID files are created for the output image.  (Default is no).

       --embedded-image
           Extract the preview image embedded in the raw file instead of converting the raw
           image.

Conversion Setting Priority

       Conversion settings are applied in the following priority order:

       1. Command-line options
       2. Settings from the configuration file specified with --conf=<ID-file> (ignoring any
       filenames in the ID-file).
       3. Settings from an ID-file supplied as an input-file.
       4. Settings from $HOME/.ufrawrc
       5. UFRaw's default settings.

       This means that an option supplied on the command-line always takes precedence over all
       other options.

       The conversion settings can be changed in the GUI before the resulting image is saved.

FILES

       $HOME/.ufrawrc - UFRaw resource file containing the user default settings.  This is an XML
       file that can be modified with any text editor. Still, it is recommended not to edit this
       file. This file is updated from the GUI when you save an image, or when you explicitly ask
       to save this file in the 'Options' menu.

       $HOME/.ufraw-gtkrc - An optional file for setting up a specific GTK theme for UFRaw.
