<DD>
Use the ICC profile embedded in the raw photo.

<A NAME="lbAH"> </A>
<H2>INTERPOLATION OPTIONS</H2>
<DL COMPACT>
<DT><B>-d</B>
<DD>
Show the raw data as a grayscale image with no interpolation.
Good for photographing black-and-white documents.
<DT><B>-D</B>
<DD>
Same as
<B>-d</B>,
but with the original unscaled pixel values.
<DT><B>-E</B>
<DD>
Same as
<B>-D</B>,
but masked pixels are not cropped.
<DT><B>-h</B>
<DD>
Output a half-size color image. Twice as fast as
<B>-q 0</B>.
<DT><B>-q 0</B>
<DD>
Use high-speed, low-quality bilinear interpolation.
<DT><B>-q 1</B>
<DD>
Use Variable Number of Gradients (VNG) interpolation.
<DT><B>-q 2</B>
<DD>
Use Patterned Pixel Grouping (PPG) interpolation.
<DT><B>-q 3</B>
<DD>
Use Adaptive Homogeneity-Directed (AHD) interpolation.
<DT><B>-f</B>
<DD>
Interpolate RGB as four colors. Use this if the output shows
false 2x2 meshes with VNG or mazes with AHD.
<DT><B>-m number_of_passes</B>
<DD>
After interpolation, clean up color artifacts by repeatedly
applying a 3x3 median filter to the R-G and B-G channels.

<H2>OUTPUT OPTIONS</H2>
By default,
<B>dcraw</B>
writes PGM/PPM/PAM with 8-bit samples, a BT.709 gamma curve,
a histogram-based white level, and no metadata.
<DL COMPACT>
<DT><B>-W</B>
<DD>
Use a fixed white level, ignoring the image histogram.
<DT><B>-b brightness</B>
<DD>
Divide the white level by this number, 1.0 by default.
<DT><B>-g power toe_slope</B>
<DD>
Set the gamma curve, by default BT.709
(<B>-g 2.222 4.5</B>).
If you prefer sRGB gamma, use
<B>-g 2.4 12.92</B>.
For a simple power curve, set the toe slope to zero.
<DT><B>-6</B>
<DD>
Write sixteen bits per sample instead of eight.
<DT><B>-4</B>
<DD>
Linear 16-bit, same as
<B>-6 -W -g 1 1</B>.
<DT><B>-T</B>
<DD>
Write TIFF with metadata instead of PGM/PPM/PAM.
<DT><B>-t [0-7,90,180,270]</B>
<DD>
Flip the output image. By default,
<B>dcraw</B>
applies the flip specified by the camera.
<B>-t 0</B>
disables all flipping.
<DT><B>-j</B>
<DD>
For Fuji Super CCD cameras, show the image tilted 45 degrees.
For cameras with non-square pixels, do not stretch the image to
its correct aspect ratio. In any case, this option guarantees
that each output pixel corresponds to one raw pixel.
<DT><B>-s [0..N-1]</B> or <B>-s all</B>
<DD>
If a file contains N raw images, choose one or "all" to decode.

<H2>FILES</H2>
<DL COMPACT>
<DT>:./.badpixels, ../.badpixels, ../../.badpixels, ...<DD>
List of your camera's dead pixels, so that
<B>dcraw</B>
can interpolate around them. Each line specifies the column,
row, and UNIX time of death for one pixel. For example:
<P>
<PRE>
962 91 1028350000 # died between August 1 and 4, 2002
1285 1067 0 # don't know when this pixel died
</PRE>
<P>
These coordinates are before any cropping or rotation, so use
<B>dcraw -j -t 0</B>
to locate dead pixels.
