Installing Adobe DNG converter

You can add a RAW to DNG format conversion feature to RoboImport by following these steps:

1.Download the Adobe free DNG Converter from
2.Go to the Options (Edit > Options) and select the Actions page.
3.Check the Convert RAW files to DNG option.
4.Click on the Customize button to adjust conversion parameters.
5.Locate your downloaded Adobe DNG converter on your PC.


Set the destination for converted files

Here are the destination options:
Save converted files in the same folder as the RAW files folder.
Save converted files in a different folder.
Specify a new sub folder for each batch of newly converted DNG files (It could be called "DNG"). To do this select Save Converted Image In Parent Folder Location option. Then type "DNG" or "\DNG" for the Create Sub-Folder option.


DNG Preferences

You can select from three DNG output formats.

Compressed DNG Files - the image data will be compressed using a lossless compression algorithm.

Uncompressed DNG files - the image data will be stored in the original "mosaic" format, if possible. This maximizes the amount of data preserved. Mosaic image data can be converted to linear data but the reverse conversion is not possible.

Linear DNG files - the image data is stored in an interpolated  ("demosaiced") format. This can be useful if a camera's particular mosaic pattern is not supported by your DNG reader.


DNG JPEG Preview Size

You can embed the JPEG preview file into the DNG file. This allows third-party software to quickly display the preview JPEG files rather than incurring the time overhead of parsing the RAW data.

A full-Size or medium sized preview (longest side is 1024 pixels) is available.


Embed original RAW file

If this feature is enabled the entire raw file is embedded inside the DNG file. This creates a larger DNG file but it does allow the original raw file to be extracted later if needed.


Delete Original file after conversion

You can delete the original RAW file after DNG conversion. The original RAW file will only be deleted if the DNG verification procedure confirms that the image was converted successfully.

Please note that enabling this feature deletes only the copied RAW file on your PC. The original source file on camera or elsewhere on disc is left untouched. To delete the source file on the input device please follow the Options > After Transfer > Delete source files after transfer.


Map IPTC Data into the DNG XMP Section

The DNG format allows you to store picture and camera information within the image files to an XMP section.

RoboImport supports mapping of IPTC information to the XMP section of a DNG format file. To enable this feature make sure that: The Map IPTC Data into the DNG XMP and IPTC Editor > Fill IPTC data for transferred images options are both checked.

You can learn more about how IPTC metadata can be used within the XMP (Extensible Metadata Platform framework) section here: http://www.iptc.org/IPTC4XMP.
