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
