NAME
makedng - pack raw sensor data into a dng file with metadata
SYNOPSIS
makedng [OPTIONS] input-file output-file
OPTIONS := { -w width | -h height | -p pixfmt | -m make,model | -s software | -o orientation | -n r,g,b |
-b r,g,b | -e program }
DESCRIPTION
Read raw sensor data from a file and generate a DNG 1.4 compliant file with the metadata to correctly
render the file.
OPTIONS
-w width, -h height, --width width, --height height
Set the width and height of the source data. This is a required option.
-p pixelfmt, --pixfmt pixelfmt
Set the pixelformat for the source data. This accepts a V4L2 fourcc code or the V4L constant name
like "RGGB" and "SRGGB8". This is a required option.
-m make,model, --model make,model
Set the camera Make and Model as a comma separated string.
-s software, --software software
Set the name of the camera software used to take the picture.
-o orientation, --orientation orientation
Set the orientation of the image data as a number from 1-8 from the DNG specification.
-c dcp-file, --calibration dcp-file
Load a DCP calibration file and append the color profile to the final DNG.
-n red,green,blue, --neutral red,green,blue
Set the neutral whitepoint for the picture as the 3 floating point gain values.
-b red,green,blue, --balance red,green,blue
Set the analog sensor gain for the three color channels as three comma separated floats.
-e program, --program program
Set the exposure program in the EXIF data using one of the program numbers from the DNG spec.
-t seconds, --exposure seconds
Set the exposure time for the picture in seconds (eg. 0.01 for 1/100)
-i iso-speed, --iso iso-speed
Set the ISO speed rating for the picture
-f fnumber, --fnumber fnumber
Set the aperture size, or f-number of the picture (2.2 for f/2.2)
-l focal-length,crop-factor | -l focal-length, --focal-length len,crop, --focal-length len
Set the focal length for the lens. If no crop factor for the system is supplied a 35mm full-frame
sensor is assumed.
PIXEL FORMATS
The pixel format argument accepts the following values:
8-bit bayer formatted data, this matches with MIPI RAW8:
RGGB, SRGGB8: RG,GB bayer pixel data
GRBG, SGRBG8: GR,BG bayer pixel data
GBRG, SGBRG8: GB,RG bayer pixel data
BGGR, SBGGR8: BG,GR bayer pixel data
10-bit bayer formatted data. transmitted as 16-bit format in 8 bytes:
RG10, SRGGB10: RG,GB bayer pixel data
BA10, SGRBG10: GR,BG bayer pixel data
GB10, SGBRG10: GB,RG bayer pixel data
BG10, SBGGR10: BG,GR bayer pixel data
10-bit bayer formatted data packed into 5 bytes, this matches with MIPI RAW10:
pRAA, SRGGB10P: RG,GB bayer pixel data
pgAA, SGRBG10P: GR,BG bayer pixel data
pGAA, SGBRG10P: GB,RG bayer pixel data
pBAA, SBGGR10P: BG,GR bayer pixel data
12-bit bayer formatted data, transmitted as 16-bit format in 8 bytes:

EXPOSURE PROGRAMS
The defined exposure programs in the DNG specification are:
• 0: Undefined exposure program (default)
• 1: Full manual program
• 2: Full auto program
• 3: Aperture priority
• 4: Shutter priority
• 5: Creative program
• 6: Action program (fast shutter)
• 7: Portrait program (Large aperture)
• 8: Landscape program (Small aperture)
