# 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 seperated 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 seperated 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.
