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.

       --maximize-window
	   Force window	to be maximized.

       --silent
	   Do not display any messages during conversion. This option is only
	   valid with 'ufraw-batch'.

       --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.

       --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 8.00. Default 1.0, use 0
	   for black & white output.

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

       --hotpixel-sensitivity=VALUE
	   Sensitivity for detecting and shaving hot pixels (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 color
	   filter array	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).

       --grayscale-mixer=RED,GREEN,BLUE
	   Grayscale mixer values to use (default 1,1,1).

       --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.

       --auto-crop
	   Crop	the output automatically.

       --aspect-ratio X:Y
	   Set crop area aspect	ratio.

       --lensfun=none|auto
	   Do not apply	lens correction	or try to apply	correction by auto-
	   detecting the lens (default auto).

       --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. This option is only valid with
	   'ufraw-batch'.

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 or $HOME/.config/ufrawrc (depending on the system) -
       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.
