Pentax k-5 dng files bug

The color rendering of the DNG files from Pentax K-5 after the update is definitely not correct (a lot of purple), the PEF files on the contrary are ok as the DNG files were prior the update.

For the K-x, this is now working correctly, where before it had massive color shift problems.
I did find rendering on some images was still going wonkey however.
I found that if I selected the image(s), and then re-rendered it using the updated conversion method in the HUD, color would be corrected.
If that by itself didn't work, I would then do a "reset all adjustments" in the tool area of the HUD, and colors would be okay.
Took awhile to re-render 60k images, but they all look fine now.
I think I will do a Vault update and a library rebuild after this is all done, just to clean and back things up.

Is there some secret to getting Pentax K-3 .dng files to display thumbnails when importing to an iPad (mini w/retina)? Files import fine, but no thumbnail. Mac OS has compatability with those files.

Is there some secret to getting Pentax K-3 .dng files to display thumbnails when importing to an iPad (mini w/retina)? Files import fine, but no thumbnail. Mac OS had compatibility with those files added long ago. Am I missing something?

I agree Terrance. However, I was able to copy other large batches of other files (my music for example) without any issues. The issue only showed up when copying iPhoto's library and/or the photos themselves. This was repeated 3 times; I copied all my other files to the drive then it unmounted on iPhoto. And, as I said, again when I started with a fresh reformat and just iPhoto. That does not seem like hardware to me if it is only happening with one set of files.
I have managed to get the iPhoto library to work on my other external drive. It wanted a rebuild twice and a thumbnail rebuild once. I am now attempting to copy it over to the new HGST internal drive.
Anyone have a suggestion for alternatives to iPhoto? I have aperture, maybe I will try that. But from what I understand, it just shares the same library as iPhoto.

DNG files from Pentax k10d in iPhoto?

I have just stated shooting with my new Pentax k10d. A great camera that are able to save not only pentax RAW (PEF) but also DNG files. My old camera is a Canon 300D, I have been using iPhoto 6 as organizer and intend do so even now.
I thought that iPhoto supported DNG, but it can not read any file other than jpeg from the k10d! Really frustating.
Do I have to wait for an update, and for how long? Is there anybody out there who knows?

Martinst:
We have no idea when or if iPhoto will support DNG files. They seem to be preferred by many professional photographers for a number of reasons. We'll just have to wait for iLife 07 to see what iPhoto has added.
However, have you downloaded the Digital Camera RAW Support Update 1.0.1 (PPC). It includes some DNG support.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

EXIF Data Lost for Edited DNG Files

I'm having an issue where my photo's EXIF data is lost when I export the picture from iPhoto. This only happens after I edit a RAW (DNG) file and export it. If I export the RAW file before editing the EXIF data is fine. Is this a bug?
System Info:
iPhoto v.7.1.3
RAW format type is Adobe DNG.
Camera is Pentax K10D
Mac OS X v.10.5.2.

I've been having the same trouble for a few months now. All EXIF is lost, including GPS and focal info. It only occurs when you edit a RAW/DNG file and have the "save edits as 16-bit tiffs" selected in the preferences. Please, Apple, help! This is a significant issue when exporting photos! That info is essential.
thanks,
Brett

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
Good luck! And let us know how it works out.

Why will CS4 not open DNG files converted from Olympus E-M1 raw files?

For several years I have been able to use the DNG Converter to convert .ORF raw files from my Olympus E-M1 and then open them for processing in CS4. Suddenly CS4 quit recognizing these DNG files saying "Photoshop could not complete your request because Photoshop does not recognize this type of file"
I have not changed any preferences. I'm using E-M1 v3.0, DNG Converter v8.3.0.141 on a Mac. I have deleted DNG converter several times, even reinstalled an earlier version but nothing changes.
However, CS4 will open DNG files converted from Pentax raw .PEF files from my K-5. Weird. It's the Olympus raw DNG conversions that won't open.
I can view the DNG converted files in question in Mac's Preview just fine but not CS4. Any ideas will be appreciated.

Be sure the DNG Converter's compatibility is set to provide support for your version of ACR:

DNG files created from Fujifilm FinePix E-900 .RAF raw files

I'm having a problem in creating DNG files from my Fujifilm FinePix E-900 camera .RAF raw files on my Mac (Mac OS X 10.6.4). The DNG files are recognized correctly in Adobe software (Photoshop CS4, Bridge, Lightroom 3) but not by any Apple software (including Aperture 3.0).
I've used Adobe DNG Converter 6.1, Photoshop CS4, and Lightroom 3 to create these non-linear DNG files. As a point of reference, I've used the same settings to create DNG files from Kodak .KDC raws files that Apple also doesn't support, but these DNG files (created from the .KDC raw files) show up just fine in Aperture 3.0.
The one thing I find unusual about the .DNG files created from the Fujifilm FineFix E-900 .RAF raw files is that when I do a 'Get Info' on these files, the image dimensions of these .DNG files always shows up as 0 x 0. (The image dimensions should be listed as 3488 x 2616.)
So I'm wondering if there is something wrong (a bug maybe) on how these files are being converted to the DNG file format using Adobe DNG Converter 6.1, Photoshop CS4 or Lightroom 3 on a Mac.

Hi Frank, you need camera Raw 7.4 which is only available for PSE11. Consider upgrading or wait for PSE12 to be launched soon. If you regularly shoot raw try Lightroom with PSE10 as your external editor.
Alternatively, download and install the free Adobe DNG converter to convert your raw files to the Adobe universal Raw format and the files will open in PSE10 (keep your originals as backups and for use in the camera manufactures software)
Windows download (.exe file) click here DNG Converter 8.1
Mac download (.dmg file) click here DNG Converter 8.1
You can convert a whole folder of raw images in one click. See this quick video tutorial:

Lightroom and Samsung GX-10 DNG files

Hi
i've got a problem with LR and the samsung GX-10 DNG file format.
It semmes that LR does not read correctly this Raw file
at the begin of the rendering, the image has good colors but they change at the end of the rendering. Colors are more dark and finally the photo is not nice.
I've done the same test with raw therapee and the rendering is better.
Have you got informations about.
It's such a pity because LR is great. i like it !
regards

yeah,, I know about raw data , and yes, wrong or not, the rendition of gx-10 pictures are very "bad" compared with other softwares and with my eyes, and I think that you can understand when i said "bad" no?, there aren't a wrong or correct in raw color but the people speaks about the wrong o correct colors all the time, i think that you understand when speak about bad colors, a bad WB , etc.
I know that i can make my own profile but is not easy, to generate a good profile I need a Macbeth ColorChecker or something like that for example and precise sources of light (like a tungsten) and taking account about that samsung cameras are "clones" of the pentax ones and that samsung shoots in DNG format (and not a propietary raw format) seems easy solve the problem about color interpretation of GX-10. With time I will buy a color-checker and try, but would be great a correct interpretaion of the own samsung colors
PD2: When i know about samsung "adobe-DNG" capacity, i didn't expect have problems with adobe soft and color intrepretation or something like that.
PD: Sorry , I don't speak english well, and so I can't express me very well , only basics

LR4 Beta crashes when accessing DNG files

I am experiencing problems using 64 bit Win 7 and LR4. LR4 seems to crash every time I try to "DEVELOP" a dng format image that was created (imported from Raw) with LR3. I am not having the problem with the CR2 or JPG images although my processing speed seems extremely slow. The images were originally created with a Canon 7D or a Canon G12.

Bill,
It is my understanding that there is a known bug opening DNG files that have previously been developed under PV2010. The bug seems to cause a crash when they are first accessed in the Develop Module. Try fresh images from the camera for testing purposes and see if you get the same crash. You shouldn't, and this will allow you to test the new features and provide feedback.

What kind of DNG file for DNG profile editor ?

Can somebody help me??? I have a problem to use DNG profile:
I am user of Fujifilm S5Pro, which has RAF file (=raw). The ACR (start from version 3...) and DNG understand my RAF files very well. But DNG profile editor dose not want to open it, even if Adobe DNG Converter 4.5 converts it to DNG file. My workflow is:
Launch Adobe DNG Converter.exe, => convert RAF to DNG (tryed different settings);
Launch DNG profile editor, => trying to open DNG file => have error???
May be I'm doing in a wrong way? Please advise me.

I tried to do the same on other PC with Vista (fully English). Also update DNG converter up to 4.6. And no success... :-(.
Every time I have the same error: "DNG Profile Editor could not open the selected image. Note that the selected image must be a valid DNG color image."
I could not understand... where is a bug.
Moreover, I took NEF from Nikon D80 and CR2 from Canon 20D and converted them to DNGs by converter 4.6. DNG Profile Editor did not want to open them on both Windows Vista and XP, and made the same error.
Do I really do wrong things? I'm completely lost
Thanks in advance,
Slava

Update old DNG files in LR?

I have some old DNG files converted in LR 1.0. How do I make sure that this files are updated to the latest version of the DNG standard and with the latest improvements and bug fixes for my cameras raw format? Is this handled while I save metadata or do I have to update the DNG file?
Can anybody from Adobe explain why there is hopefully no difference between having a file converted 2 years ago compared to having a nef file and convert it to day with latest version of the DNG converter?

I'm not from Adobe, but IIRC (If I Remember Correctly), you can upgrade the DNGs with the latest version of the DNG converter.

.dng files do not open full size in PS CC

I've been working with Canon .CR2 files and later Adobe .dng files for years, and could always open them in Photoshop. Now, with PS CC, the files open as small previews (420 x 280 px) instead of the full size. This means I cannot work with my photographs!!!! I haven't found a setting in either Bridge or PS to correct this.

I open pic files by either double-clicking on them in Bridge or on the desktop, or using "Open" from within PS. iPhoto is not involved at all. It's not something funny I'm doing; it's a bug in PS CC (I've been using PS since 1990).

Big DNG files from E-P1 RAWs

Hi,
I am converting RAW files from my E-P1 to DNG using the new DNG Converter 5.5RC. To use the DNGs in Lightroom 1.0 I have to use "Camera RAW 4.6 and newer" as compatibility setting. This results in extremly big DNG files (I did not embed the original RAW).
original ORF file:12.2 MB
converted DNG 4.6: 46.6 MB
converted DNG 5.4: 12.7 MB
This problem only occurs with pictures taken with the olympus kit lens. Pictures taken with an old adapted manual lens don't have that problem. I suspect that the problem relates to the lens corretion data, that is only present with the kit lens.
Does anyone have the same problem? Is this a general problem with old DNG versions or a bug in the DNG Converter 5.5RC?
Thanks,
Michael

Can not you disable the lens correction feature in your camera?
I am not speaking for Adobe, but I "feel their pain": the Oly lens correction is only one feature of many-many among all native raw files. If the DNG interface contained options for all featires, which may be reasonable candidate for disabling, the dialog would become horrendeous.
The core of the problem is, that the previous DNG version [i]could not[/i] carry the lens correction info, for the specification did not have a respective element for that. Therefor the DNG converter has to perform the correction itself, instead of letting the "real" raw processing do that. This has been mended in the newer version, i.e. the DNG converter can now "pass" the lens correction info to the raw processor in meta format, the raw data itself does not need to be changed during the conversion in DNG.

LR 3 and DNG files created and edited in LR 2

Workflow had been to import Nikon NEF files, convert to DNG in LR2, do my edits, and save the data within the DNG file. Tried to upgrade to LR3 tonight, using the trial version while I wait for my package to arrive. The catalog migrated just fine, with the exception that the edited DNG files were ignored.
DNG files that had not been edited seem to have imported just fine. But what fun is that. I need access to all my DNG files to continue the editing that I had been doing in LR2.
I verified the DNG files were still on the computer. I then tried to sync one of the folders I knew had edited DNG files in it that hadn't been migrated in the catalog import. LR 3 refuses to acknowledge the files exist, and doesn't give me the option to import them. :-(
Is there some option or preference I need to set/reset? Is this a known bug or issue? Is there a workaround?
Computer is a Intel Quad Core with 4 GB running WinXP Pro.
Thanks in advance,
- Arved

I don't remember what the settings were when I imported the catalog. Whatever the defaults were.
Whatever happened during import, I should still have the option to add the files when sync'ing a folder? But I don't.
Neither LR2 nor LR3 will allow me access to the edited DNG files now. I've erased and am rebuilding the catalog (all pertinent info was written to sidecar and/or within the DNG file, so I'm not anticipating any problems with this. It's showing the expected 27,000+ files being imported). I think I'll try building the LR3 catalog the same way when I fire it back up, once I'm sure I'm back up and running in LR2.
Thanks for the quick response!

DNG files labeled as Unsupported Image Format

I have used the Adobe DNG Converter and LIghtroom 3 to convert some raw image files from a Fujifilm S100fs camera, and then tried to import them into Aperture 3. In all cases, DNG files from this particular camera are labeled Unsupported Image Format, while DNG files converted from other unsupported cameras have been imported successfully into Aperture.
I think this is clearly a defect in Aperture that should be fixed, and I would like to know how a user is informed by Apple that a behavior has been identified as a defect and put on a list of problems to be fixed.

I can now add more details to my problem with Apple's treatment of DNG files originating from .RAF files created by the Fujifilm S100fs camera.
I took this issue to the Adobe DNG Converter forum, to investigate whether the DNG Converter was creating a Linear DNG file from these originals. I had read on Apple forums that the MAC OS would reject DNG files that were linear, and that this sometimes happens when the Adobe Converter encounters raw file parameters that it cannot handle, such as barrel distortion correction figures.
I have established that these DNG files from my S100fs camera RAWs are NOT linear DNG's. I found a helpful reader on the Adobe forum who had the tools and knowledge to look inside my DNG files, and ascertain that they were not Linear DNGs.
So I have exhausted the possibilities that the MAC OS is rejecting my DNG files for a recognized valid reason, and I return to my opinion that this is an Apple bug and needs to be fixed.
