NAME
dcraw - command-line decoder for raw digital photosSYNOPSIS
fldcraw [OPTION]... [FILE]...DESCRIPTION
fldcraw 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 fldcraw can decode the last file, 1 if it can't. -i -v shows metadata.
- fldcraw 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, fldcraw 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 fldcraw -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, fldcraw applies the flip specified by the camera. -t 0 disables all flipping.
- -s [0-99]
- Select which raw image to decode if the file contains more than one. For example, Fuji Super CCD SR cameras generate a second image underexposed four stops to show detail in the highlights.
- -j
- For Fuji Super CCD cameras, show the image tilted 45 degrees, so that each output pixel corresponds to one raw pixel.
- For most cameras, -s and -j are silently ignored.
