5D Mark II .dng files

I am converting 10MP (sRAW1) .cr2 files from a 5D Mark II to .dng using vers 5.2 of the DNG converter. My .cr2 files are usually around 15 megabytes (+/- a couple of megabytes) but I've discovered the .dng files are well over 20 megabytes. Why are they so much bigger than the .cr2 files? When I converted files from my older cameras (10D/20D, 5D) the .dng files were usually 10-15 percent smaller.
thanks,
jack

The sRaw is a special, semi-raw format, demosaiced but not color space converted. It is tri-color, but not every pixel has all three color components. When converted to DNG, the converter "invents" the missing color values; thus there is much more data in DNG format than in sRaw.

Can't open dng file in Photoshop cs5 from Lightroom 5.6

Hello, I've searched around and can't find the answer to my question.
Technical details:
OS X v10.8.5
Photoshop CS5 (ver12.1) Camera Raw ver 6.7.1.340
Lightroom ver 5.6 (Camera Raw ver8.6)
Camera: Nikon D600
Minimum camera raw version to support D600 Raw is ver 7.3 and Lightroom ver 4.3
I know that my version of PS doesn't support my Nikon D600 raw files so I've used the Adobe DNG converter and converted a raw file so I can process in PS. I can open the DNG file directly in PS and get the ACR screen to perform my edits. However, what I really want to do is open the DNG file in PS from LR.
While in LR, if I select Edit in -> Adobe Photoshop CS5, I get the notification from LR that "This version of Lightroom may require the Photoshop Camera raw plug-in version 8.6 for full compatibility". I would have expected that regardless of whether I opened the (same) dng file from PS or LR (and edit in PS), that once in PS. the ACR screen in PS would be presented. Can anyone explain to me why this is the case and if this is normal or expected behaviour? Thanks
Also:
Adobe DNG converter preferences = Use Camera Raw 6.6 and later
Lightroom preferences = File Handling -> Use Camera Raw 6.6 and later
Thank you in advance,
Mark

As Station_two mentioned, you're using a version of LR that is not compatible with the older version of PS CS5. I don't know it LR has the ability to save DNGs to work in older versions of PS. If not, you will need a DNG converter to save them to the version of Camera Raw that PS CS5 can handle or upgrade PS.

Convert RAW Files in Your Aperture Database to Adobe DNG Files

The following describes how to convert all the RAW images in your Aperture database from manufacturer formats, such as Sony's ARW and Canon's CR2, to Adobe's DNG while retaining all the Adjustments already applied to your RAW files. In the example below I am assuming that your Aperture Library has ARW and CR2 files. These steps work with the latest version of Aperture, being Version 3.3, and have not been tested with earlier versions (in fact, it probably will not work because the database structure changed in 3.3 - however, this means that the steps below can also be applied to your iPhoto library). The steps are:
1. Within Finder select the Aperture Library and Secondary Click to bring up the Shortcut Menu. From this select "Show Package Contents"; this will open a Window showing all the files/directories contained within your Aperture Library.
2. Drag the "Masters" folder out of the Package and place it on your Desktop. The purpose of this step is so that Applications, such as Adobe DNG Converter, can "see" the "Masters" folder, which they cannot do if it is located within the Aperture Library Package.
3. Run the Adobe DNG Converter, select the above "Masters" folder with the "Select Folder" button, make sure you have selected the option "Save in the Same Location", it is also a good idea to select the option "Skip source image if the destination already exists", check your Preferences then select the "Convert" button.
4. Adobe DNG Converter will now convert all the RAW files to Adobe DNG files and save them in the same location as your existing RAW files. Once complete, take a note of (a) the number of files converted and (b) the types of files converted, such as if the conversion includes ARW, CR2, NEF files etc. In this example I will assume that the converter only found ARW and CR2 files; if your system is different then modify the steps below to make sure it covers all the RAW file types converted in your particular system.
5. Select the "Masters" folder and in the Finder Window Search Field search for all the files that end in .ARW and .CR2 (this filename search list should match the types of files found by the Adobe DNG Converter in step (4)(b) above). The number of files returned by the search must match the number of files recorded by the Adobe DNG Converter in step (4)(a) above. Do NOT put the .DNG files in your search criteria. Select all the files found in the search and move them to the Trash. This will delete all the original manufacturer's RAW files from your Aperture Library leaving behind all the new DNG files.
6. Move the "Masters" folder on your Desktop back to the root directory of the Aperture Library Package Content directory.
7. Select the Finder Window containing the Aperture Library Package Contents.
8. If there is a file called "ApertureData.xml" then open it with a text editor. Search and Replace ".arw" with ".dng", ".ARW" with ".DNG", ".cr2" with ".dng" and ".CR2" with ".DNG" (note, do not use the " marks in your search). Make sure you cover all the file types incorporated in your particular system. Save the "ApertureData.xml" file.
9. Traverse to the Database/apdb directory. Select the "BigBlobs.apdb" file and open it with a Hex editor. In this example I will use Hex Fiend by Ridiculous Fish (see http://ridiculousfish.com/hexfiend/). Once the file is open perform a Find and Replace ensuring you are finding and replacing Text and not Hex. In Hex Fiend this means selecting Edit/Find from the menu and then selecting the "Text" button to the top/left of the window. In your Find/Replace field you will need to find ".arw" and replace it with ".dng", make sure you select "Replace All" (note, do not use the " marks in your search). Do exactly the same for ".ARW" with ".DNG", ".cr2" with ".dng" and ".CR2" with ".DNG" (and whatever particular RAW files were in your system).
10. Perform exactly the same steps in (9) for the files "History.apdb", "ImageProxies.apdb", "Library.apdb" and "Properties.apdb".
That is it, your Aperture Library now contains DNG files instead of your original manufacturer files while still retaining all the Adjustments originally made in Aperture to those manufacturer files. Of course, you can repeat the same step and replace your DNG files with the original RAW manufacturer files if you wish. This process works because:
1. Aperture does not store the Adjustments in the RAW files, it keeps these in its internal SQLite database.
2. By using a Hex Editor you (a) don't have to play with SQLite to gain access to Aperture's data and (b) because you are replacing text that has exactly the same number of characters you are not invalidating the format of the underlying data file - this is why you use a Hex Editor instead of a simple text editor.
Think of Aperture as being a repository that holds Adjustments which then link to the original RAW source. Therefore, the above process simply replaces your RAW source and therefore all the Aperture Adjustments are still valid; same Adjustments, new source. In case you ask, no, you cannot transfer Adjustments in and out of Aperture because there is no standard to transform adjustments between different photographic applications.

A rather involved method, David.
I am sure it works, and compliments for figuring it out, but I think one critical step is missing in your workflow: Before you begin - backup, backup, backup!
And I think, all the edits in your database that you are doing so diligently, is what you bought Aperture for to do for you, why do it yourself?
I convert selected raw files this way - without manually patching the Aperture Library:
Export the originals of the raw images that I want to convert.
Run dng-converter.
Import the converted originals back, flag them, and move them to the project they came from.
Sort the project by capture date, so that identical images are show side by side.
Then I use the Lift&Stamp tool to transfer all adjustments and tags from the original raw to the dng copy. I check, if some edits are left to do, then delete the original.
It may take a little longer than your method, but this way all edits in the library are done by Aperture, and I am protected from accidental slips when editing the property list files. That requires a very careful work.
Patching the database files inside the library may be justified as a last ressort, when you need to fix and recue a broken Aperture library, and none of the provided tools is working, but not as a routine operation to do batch conversion of image files. It is very error prone. One wrong entry in the library files and your Aperture Library may be unreadable.

Canon 5D mark II raw file conversion size blowout

I am suffering from an issue where my CR2 files from a 5D decrease in size when converted to DNG from for example 14.4MB to 11.8MB while the 5D mark II files increase from 8.7MB to a much larger 23.6MB after conversion. Both conversions are being done with DNG Converter 5.4 using the same preferences. Any light you could shine on this for me would be greatly appreciated.

It is because your 5D Mark II files are sRAW images, not raw. (The full 5D Mark II raw files are usually over 20 MB, not ~8 MB.) When you process sRAW files into DNG files, the DNG files are stored in the "linear DNG" format, which is much bigger than the sRAW format.
p.s., these questions should be directed to the Camera Raw, Lightroom, or DNG forums in the future to get a faster reply.

Import DNG files processed in Bridge CS3

I have imported 500 DNG files that have had some adjustments made to them in Adobe Bridge CS3. Aperture 2 does not seem to recognise the RAW adjustments that have been made in Bridge. I copied some of the DNG files to a DVD and then opened the DVD on another computer that has Bridge and the adjustments stick with the DNG file. How can you import DNG files into Aperture 2 that have been processed in Bridge without having to make the adjustments again?

{quote:title=Mark P A wrote:}How can you import DNG files into Aperture 2 that have been processed in Bridge without having to make the adjustments again?{quote}
You can't. The raw conversion made by ACR can not be read by Aperture and vice versa. The only reason you can read the settings in the DNG- file on another computer with ACR is that the sidecar file is embedded in the DNG. If you had not converted to DNG, then you had to export the XML- sidecar file as well if you wanted ACR on the other computer read the settings made to the raw file.

Aperture 3 will not read LX3 .dng files

I was a Lightroom user for the past several years, but have decided to give Aperture a try. I converted files from my Panasonic Lumix LX-3, Canon 5D Mark II, and Canon s90IS to .dng when they were imported into Lightroom. I no longer have the original RAW files.
I have imported these .dng files into Aperture 3. The two sets of Canon files import properly and our easily edited. The .dng files from the Panasonic Lumix LX3 do not import properly. I get the "unsupported image format" message on the thumbnail.
I have installed the latest Apple update that allows for support of the LX3.
This has happened on both my Mac Pro and Macbook Pro.
Is anyone else experiencing a similar issue?
Thanks,
Fred

Hi Fred. Saw your post about this on dpreview, too. I'll repost my response here for other Apple folk.
I'm seeing this with DNGs from my G1, too. The problem seems to be that Aperture 3 lacks support for lens corrections in DNG.
It is probably not a problem with Linear DNGs -- though you'd have to check yours. Adobe forced Linear DNGs on G1 and LX3 users for only one version of DNG converter (5.4, if I remember right). After that, they figured out how to do lens correction inside regular raw DNGs -- the kind that Aperture supports.
Except that the lens correction in those DNGs seems to confuse Aperture 3. It's odd because for the G1 and LX-3, Aperture supports those same corrections in the native RW2 format. Let's hope it's a bug that the same corrections don't work in DNG.
In the meantime, there are a couple of options:
1. Wait for RW2 support. For the GF1, this is your best choice. And save those RW2 files! Extract your original RW2 files from the DNGs or pull them from a backup (you did embed the the RW2, right?). If you've shot with Panasonic micro 4/3 lenses, this is your best option.
2. If your DNGs were shot with legacy lenses, there is a good work-around. Only native Panasonic (and maybe Olympus) micro 4/3 lenses add the lens metadata. If you don't have that, the only thing keeping Aperture from recognizing your photos is the camera model name embedded in the DNGs. You can use something like exiftool to change it to one that doesn't do lens correction. Here's what I use to get my G1's legacy lens DNGs to work in Aperture 3. (This is not terribly dangerous, as exiftool can just as easily undo this change.)
exiftool -Model=DMC-L10 blah.dng
3. If your DNGs do have lens correction (as they must with the LX3) you could use a tool like DNGSanitize http://punainenkala.livejournal.com/588.html, which purports to strip the lens correction from the DNGs. This is a last-resort sort of thing to do, you will lose that lens correction data. You would probably also have to change the camera model name, as in option 2 (try DMC-FZ50 for the LX3). Keep backups. And, really, don't do this -- wait until the next release of Aperture when we'll find out if Apple intends to fix DNG support.
Whatever you do, test this with your DNGs -- especially if you're trying option 2 or (especially) 3. Just because option 2 works for me, that doesn't mean it will for you. And I've not had to try option 3. And pray you don't have linear DNGs, as only Adobe can help you then.
I can't believe that Apple would mess up DNG support this badly on purpose. In the meantime, please file a bug report to let Apple know that losing DNG support for these cameras is a big deal. You can do this from inside Aperture itself. Choose Aperture > Provide Aperture Feedback from the menu.
Here are the gory details, with links to helpful resources -- http://elstudio.us/notes-on-aperture-3-and-panasonic-gf1-rw2-and

I'm considering buying CC LR/PS package. My camera is Sony a7 - raw ARW. I've been editing using PSE10 and ver 8.7 of the external Adobe DNG converter. Will I be able to open the DNG files in LR with the edits preserved? Will I be able to open the PSD files in LR with the edits preserved? Any import/catalog etc issues between PSE10 and LR?

Lightroom has no problem reading DNG files. Whether the edits you have done to the DNGs you have originally edited in Photoshop Elements 10 I'm not sure. ACR edits made to DNGs are saved in the DNG file itself, as apposed to a XMP sidecar file, so LR should see those edits. At the worst you will get an exclamation mark in the upper right hand corner of the imported DNGs and clicking on that exclamation mark you will get a dialog box asking you to either import settings from disk or overwrite settings. you would select import settings from disk.

7D mark II raw files won't open using CS5. Help.

Canon 7d mark II raw files open error

Photoshop elements 12 will not open the canon 7d mark II raw files, from what I read elements are not going to upgrade there camera profiles anymore, so anything new your just out of luck? The support people have no clue.

Faq:
FAQ: Will Photoshop Elements work with my camera, or Why won't my raw files open?
more specifically:
Camera Raw plug-in | Supported cameras
in which you find that your camera requires the ACR 8.7 version
Camera Raw-compatible Adobe applications
in which you see that PSE12 can't, and that PS13 can with an update.
So what solution, since Adobe does not upgrade older versions? It's the free Adobe DNGconverter:
Use the latest version of the free DNG Converter (for Macintosh or Windows)
You can convert your files to the universaly compatible DNG format (the files will work with any version of the Camera Raw plug-in). See In depth : Digital Negative (DNG) for more information.
This standalone utility lets you batch convert whole folders of raw files to the DNG raw format that your PSE12 can read.

Will Lightroom 4 get updated with support for Canon 7D Mark II Raw Files?

I received an update for Photoshop to support Canon 7D Mark II raw files (ACR 8.7), will Lightroom 4.4 get an update to support these files?

I don't know why you feel it makes things more complex. All you need to do is use the DNG converter as your download software. The conversion takes place during the download, and then you can import directly into Lightroom. I'm not trying to sell you on using DNG. But it isn't as cumbersome as it seems.
Since Lightroom doesn't utilize the Camera Raw plug-in, it makes it more difficult to provide updates. In Lightroom update means distributing a whole new Lightroom program.

Why are my RAW dng files opening in photoshop as 8 bit?

I am shootng on the canon 5 D Mark II.
On other Mark II camera bodies that I used in the past, the dng files are 16 bit. Why are mine 8 bit, and how can I change it IN CAMERA to 16 bit (I know how to convert it in photoshop,)
thanks

DNG is an Adobe standard which stands for "Digital NeGative". Adobe supports the format and have also contributed it as an open standard (free to use, they provide free DNG converters, they also state that it's "royalty free" if you were a developer and wanted to include the standard in a product, etc.)
You can find more information on it (and download Adobe's own free DNG converter software) here: http://www.adobe.com/products/photoshop/extend.displayTab2.edu.html
And while it's supported by several companies even outside Adobe, it isn't adopted by Canon or Nikon -- they continue to create files in their own formats (.cr2 for Canon and .nef for Nikon).
Are you using Adobe's DNG Converter or something else?
JPEG is an 8-bit format (there is no option for anything other than 8-bit if you shoot JPEG).
CR2 (Canon RAW) is a 14-bit format on your specific camera.
If you shoot RAW and copy the CR2 files to your computer, you've got 14-bit data (there is no option on your camera to change the bit-depth.) There are options to shoot in alternate RAW formats such as S-RAW1 & S-RAW2 (don't use those if what you _really_ want is "RAW").
Canon "Digital Photo Professional" (aka "DPP") came on the media CD bundled with your camera and can open all formats that your camera can create... but 3rd party software wont necessarily support all the formats. Everyone, of course, supports JPEG. RAW is supported via RAW updates from the some vendors (e.g. Adobe provides RAW updates but usually only for their latest versions of software). The S-RAW formats are often not supported by 3rd parties.
It looks like RAW support for the 5D II was added in Adobe Camera RAW (ACR) v5.2. That was back in the days of Photoshot CS4. If you have CS4 or later (or any version of Lightroom) and you keep up with the "Adobe Camera RAW" updates then Photoshop would be able to open the Canon .CR2 files from your camera in their native format and would not need to have them converted to ".DNG" format.
Canon DPP will allow you to convert your RAW files into TIFF (which is also a non-lossy format).

Photoshop CS won't read 5.2 DNG files

I recently had a student use the stand alone DNG converter V.5.2 on his Canon 5D Mark II raw files but Photoshop CS won't read the resultant .dng files. Our copy of CS3 reads them ok but he only has CS and neither his version of CS nor ours will read the files. My understanding has been that .dng files can be read by any version of Photoshop that works with Raw files. Is this no longer true? Or was it never true? Thanks.
-dave-

Hi Thomas,
Installing 2.4 took care of the problem. Boy, does the CS version of Camera Raw seem crude compared to the full featured version you've given us now. I remember it as being pretty impressive at the time but I sure wouldn't want to have to go back to it. I think I've convinced the student how much he's missing out on by not having CS4 but at least he'll be able to work with his Raw files until he upgrades. Thanks for your help.

Canon EOS 5D Mark II DNG Not Recognized by Aperture

Hi - I recently received a hard drive with a number of DNG files shot with the 5D Mark II. When I try to import them into Aperture,
I am told that the file format is not supported. All Aperture support (book/web/help) says DNG is supported. Also, Canon 5D RAW
supported.
How can I import these files?
Thanks.
Chris

From the Aperture spec:
DNG files must be generated by the Adobe DNG Converter with the “Convert to Linear Image” option turned off.
Might be your problem.
If you can get your hands on the original RAW files that would definitely be your best bet.

Canon 5D Mark II .mov file corrupt Need help

I have one file captured during a video session that I cannot copy, edit without locking the entire computer and having to hard start the machine. I need this file to finish editing a job. All the other files from this session work flawlessly with this one exception. Any help would be greatly appreciated. Cant cut, paste, delete, save as, export, any function without crashing. When I try to export or save as it stops at a certain point and freezes the maching. Export not responding, save as not responding. Then I have to restart

It is because your 5D Mark II files are sRAW images, not raw. (The full 5D Mark II raw files are usually over 20 MB, not ~8 MB.) When you process sRAW files into DNG files, the DNG files are stored in the "linear DNG" format, which is much bigger than the sRAW format.
p.s., these questions should be directed to the Camera Raw, Lightroom, or DNG forums in the future to get a faster reply.
