Convert Raw to DNG Automator Action
|
|
Adobe’s Digital Negative Specification, or DNG format, provides an open standard for the storage of raw camera data. However, since few cameras can store directly into Digital Negative format, if you want to take advantage of DNG, you first need to convert your existing raw files to DNG format using the Adobe DNG Converter. Mac users running OS X 10.4 ("Tiger") or later can ease their conversion tasks using this Automator action, which lets you batch process your DNG conversions, as well as include DNG conversion in a more complex image processing pipeline. This updated version adds Leopard support as well as the ability to convert Sony SR2 files. |

For photographers who shoot raw, DNG offers several important advantages over proprietary formats: it’s open source, so any software or hardware vendor can support it; it won’t vanish if any particular company goes out of business; and it includes support for all raw conversion metadata, making for a more efficient, all-in-one, raw format/metadata file.
Automator, meanwhile, is an excellent workflow automation tool which allows you to create applets that automatically manage your post-production pipeline.
The Convert Raw to DNG action allows you to use Automator to drive all of your DNG conversions. You’ll need the Adobe DNG Converter 3.2 or later, a free download available here, as well as OS X 10.4 or later..

To use, simply follow the included installation instructions, and then add the action to a workflow. Configuring the action is very simple:
- If you leave the Name or Destination fields alone, then all resulting DNG files will be saved in the same location as the source, with same name as the original, appended with a ".dng" extension.
– Select a new destination to store the resulting DNGs in a different folder. Enter a new name to give each DNG file a new, sequentially numbered name.
– Configure the Output options appropriately (see the Adobe DNG Converter on-line help for more information.)
- This new version offers substantial speed improvements over the previous, 1.0 version. However, to achieve this speed increase, two previous options have been dropped. Consult the included readme for more details.

Thanks for getting this working in Leopard! It works great.
- Adam
Can not get it to work with .nef or .orf files… The action seems to always try and find .cr2 files…
Hi,
This does not work for me either
Leopard and Nikon raw files.
A message pops up: “find (…) “.cr2″ – maybe that helps?
C
ditto on .nef – does not work
Sorry guys, it now works for all file formats. Download the new version and you should be good. Unfortunately, there was also a bug in the “Check for Updates” mechanism, so it’s not working in the version you have. That’s fixed now, too.
Thank you! The new version does the trick

DNG now supported on Google Mobile Phone (gPhone)
http://teavuihuang.com/dng
Tea Vui Huang’s “DNGwriter” is a Google Android library that allows gPhone (Google Android Handset) camera images to be saved straight to the Adobe Digital Negative (DNG) Raw image format. This product includes DNG technology under license by Adobe Systems Incorporated.
Sample DNG photo is available on the above website.
Hi
Downloaded this action. Installed it with double click to automator. The action refuses to participate in any workflow (does not move to the workflow window when creating the workflow).
I can create any other kind of workflows, but raw dng converter will not want to participate.
Running 10.5.2.
Hi
Same problem. Cannot add this action. The action refuses to participate in a workflow. Any ideas?
Maybe a stupid question but is there any way I can have the Convert Raw to DNG action put the created DNG files into a subdirectory of the original directory without having to specify it at run time
Like number 8 & 9 I can’t get this action to work after installing.
Thanks a lot! I used it to convert a batch of Sony .ARW files and it worked perfectly.
Thanx a lot!
I’ve got 1 little problem though (besides my english), maybe someone can help me out.
In automator i created a hotfolder so when i shoot a raw file (tethered) the dng converter automaticly kicks in. Though with every new file I have to set up the settings of the dng converter… Since I’m new to automator mayb somebody can help me out to make a sort of default setting..
ah, nevermind, found it, DONT show action when run, like I said; new to automator….
I’ve downloaded this action, but couldn’t find any option to convert .ARW files. I’ve tried using all Sony and Minolta RAW format but as soon as I import them to Aperture, the exposure and white balance shift is so great it makes the photo look bright and pink. I tried converting manually and importing them to aperture manually and everything is fine. Is there any way this can be fixed?
Is there any way this could be made into a plug-in for Aperture so that it works in the same way as the DNG converter built into LR? This has the option of converting to DNG on import or after.
[...] kan eens proberen door je RAW bestanden om te zetten naar DNG met deze converter. [...]
This action is exactly what I was looking for…
But I have Samsung DSLR that uses uncompressed DNG format, so I usually use DNG Converter to convert DNG to DNG just to compress it (reduces the size in half, no loss of quality). Unfortunately, DNG is not one of the supported input formats.
Is there anything that can be done?
Interesting point. I’ll see what I can come up with.
Love Automator, love your work on this too! When I get paid, maybe I’ll send some your way!
You may have another way round this, but I realized that passing a to will only convert the FIRST raw file if the folder has JPEGS in it as well. Apparently doesn’t ignore them, but stops. Also, passing has same result.
I fixed this by placing a in between whichever & your
You might consider (if this is possible) allowing your action to ignore all other file formats (JPEGs etc.) to make this more user friendly, and have less hand-holding with Automator.
Great work, thanks so much.

Ooh. Ben, can you delete my last post? I used Left and Right Arrow Brackets (like html) and they were interpreted… probably as html, and deleted. That post now makes no sense at all.
Will post the corrected version next.

You may have another way round this, but I realized that passing a to [Convert Raw to DNG] will only convert the FIRST raw file if the folder has JPEGS in it as well. Apparently [Convert RAW...] doesn’t ignore them, but stops. Also, passing [Selected Item in Finder] has same result.
I fixed this by placing a [Sort Finder Items, by kind in ascending] in between whichever [Finder action] & your [Convert RAW...] action.

Thanks for the feedback, Sef. I’m hoping to re-tool this action soon, but it’s just hard to get it into the schedule. That’s a great suggestion, though.
Tell me what you're thinking...
