# makedng(1)

pack raw sensor data into a dng file with metadata

## 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:
