NAME
dcraw - command-line decoder for raw digital photos
SYNOPSIS
dcraw
[OPTION]... [FILE]...
DESCRIPTION
dcraw
decodes raw photos, displays metadata, and extracts thumbnails.
OPTIONS
-v
Print verbose messages, not just warnings and errors.
-c
Write decoded images or thumbnails to standard output.
-e
Extract the camera-generated thumbnail, not the raw image.
You'll get either a JPEG or a PPM file, depending on the camera.
-z
Change the access and modification times of an AVI, JPEG or raw
file to when the photo was taken, assuming that the camera clock
was set to Universal Time.
-i
Identify files but don't decode them.
Exit status is 0 if
dcraw
can decode the last file, 1 if it can't.
-i -v
shows metadata.
dcraw
cannot decode JPEG files!!
-d
Show the raw data as a grayscale image with no interpolation.
Good for photographing black-and-white documents.
-D
Same as
-d,
but totally raw (no color scaling).
-h
Output a half-size color image. Twice as fast as
-q 0.
-q 0
Use high-speed, low-quality bilinear interpolation.
-q 2
Use Variable Number of Gradients (VNG) interpolation.
-q 3
Use Adaptive Homogeneity-Directed (AHD) interpolation.
-f
Interpolate RGB as four colors. Use this if the output shows
false 2x2 meshes with VNG or mazes with AHD.
-B sigma_domain sigma_range
Use a bilateral filter to smooth noise while preserving edges.
sigma_domain
is in units of pixels, while
sigma_range
is in units of CIELab colorspace.
Try
-B 2 4
to start.
-b brightness
By default,
dcraw
writes 8-bit PGM/PPM/PAM with a BT.709 gamma curve and a
99th-percentile white point. If the result is too light or
too dark,
-b
lets you adjust it. Default is 1.0.
-4
Write 16-bit linear pseudo-PGM/PPM/PAM with no gamma curve,
no white point, and no
-b
option.
-T
Write TIFF output (with metadata) instead of PGM/PPM/PAM.
-k black
Set the black point. Default depends on the camera.
-a
Automatic color balance. The default is to use a fixed
color balance based on a white card photographed in sunlight.
-w
Use the color balance specified by the camera.
If this can't be found, print a warning and revert to the default.
-r mul0 mul1 mul2 mul3
Specify your own raw color balance. These multipliers can be cut
and pasted from the output of
dcraw -v.
-H 0
Clip all highlights to solid white (default).
-H 1
Leave highlights unclipped in various shades of pink.
-H 2-9
Reconstruct highlights. Low numbers favor whites; high numbers
favor colors. Try
-H 5
as a compromise. If that's not good enough, do
-H 9,
cut out the non-white highlights, and paste them into an image
generated with
-H 3.
-m
Same as
-o 0.
-o [0-5]
Select the output colorspace when the
-p
option is not used:
0
Raw color (unique to each camera)
1
sRGB D65 (default)
2
Adobe RGB (1998) D65
3
Wide Gamut RGB D65
4
Kodak ProPhoto RGB D65
5
XYZ
-p camera.icm [ -o output.icm ]
Use ICC profiles to define the camera's raw colorspace and the
desired output colorspace (sRGB by default).
-p embed
Use the ICC profile embedded in the raw photo.
-t [0-7,90,180,270]
Flip the output image. By default,
dcraw
applies the flip specified by the camera.
-t 0
disables all flipping.
-j
For Fuji Super CCD cameras, show the image tilted 45 degrees,
so that each output pixel corresponds to one raw pixel.
-s
For Fuji Super CCD SR cameras, use the secondary sensors, in
effect underexposing the image by four stops to reveal detail
in the highlights.
For all other cameras,
-j
and
-s
are silently ignored.
