Convert slide scan files to .dng?

We are scanning masses of old slide scans and bringing them into Lightroom as .tiffs.  Recently I was told that if I convert those .tiff files to .dng that would enhance developing operations in the Develop module and almost simulate working with a RAW file.
Does anyone have any experience with this process?  And any opinion about it?

The only advantage of DNG over a TIFF is its ability to retain the full RAW capture of a photographic sensor. A scanner works differently, some have a pseudo RAW format...Nikon scanners can do this scanning to the NEF format. But if you have scanned as a TIFF keep the original as a TIFF LR's functionality will be the same with a DNG made from a TIFF and the original TIFF. Whoever is telling you taht you can magically gain information by converting file types is misleading you and DNG compression (whilst the best for RAW formats, isn't any better than TIFF's so the file size remains the same as does the ability to write xmp metadata to the file (rather than as a sidecar file. In brief converting anything other than an original RAW file to the DNG format is just a waste of time.

    Metadata can be added in Properties panel. select a file and hit Alt+Enter. It will open up Properties panel. You may drag drop tags on the media and do File > Write tags info to files to write tags in file metadata.

  • Problem Converting Canon CR2 Files to DNG

    I am currently on holiday, shooting photos with my Canon 70D in raw (CR2), and I have my Macbook Air with me, with Lightroom 5.4 installed on it.  After each day's shooting, I have been putting the flash card from the camera into the laptop, and downloading the photos using Lightroom, converting the CR2 files to DNG in the process.  This was working fine until a couple of days ago when suddenly, Lightroom has decided that it can no longer do the conversion.  It displays the photos on the card, it allows me to choose the ones I want to download, and then it tells me that it cannot convert/download them because it cannot read the files.  Well, if it cannot read the files, how can it display them so that I can make my choices?  And why, after working successfully for weeks, am I suddenly getting this error message ... nothing has changed in my hardware or software in either the camera or computer.  Any and all help would be most appreciated.  Thank you!!

    Thanks very much for the answer, but I'm afraid it is not very enlightening ... at least to someone like me.  I do not understand where I would look for a write permission issue ... especially since nothing has changed (as far as I know).  Can you give me any further help?  Thanks!

  • Converting Canon .CR2 files to .dng

    I have what appears to be the latest version of the Adobe DNG Converter (8.6.0.254); but when I direct it to a folder containing .CR2 files from my Canon PowerShot G7X camera, it tells me "No items match your search" and does no conversion. How can I convert this type of RAW file to .DNG?

    I don't understand your question. Here is what I do in the Digital Negative Converter:
    - Step 1 is "Select the images to convert"; I click on "Select folder" and navigate to the folder containing a .CR2 file
    - in that window, I see "No items match your search." even though it contains a .CR2 file from my Canon camera. Whether I then click on Select or Cancel makes no difference, since the program does not recognize any files.
    - If despite that, I click on Convert, I receive an error message "The source folder does not contain any supported camera raw files."
    In other words, .CR2 raw files are not being recognized by the latest released production version of the converter.

  • Question on converting edited CR2 files to DNG

    Sorry, I cannot find a separate DNG forum. If this question is in the wrong place, please direct me to the correct forum.
    I have lots of CR2 RAW files on my computer, and I am considering converting them to DNG. Many of these RAW files have already been edited and so have a separate XMP sidecar file containing the edits in the same folder. If I convert (using the Adobe DNG converter) these edited RAW files to DNG, what is converted? The CR2 RAW file alone, so that the converted DNG file is the same as the original unedited CR2 file? If so, what happens to the orphaned XMP file? Ignored?
    My concern is that I will lose all RAW edits if I convert to DNG because the conversion process ignores the edits contained in the separate XMP file.
    Can someone explain this to me? Thanks.

    So what you're saying is that the DNG conversion de-mosaics the image?  I guess that's not surprising, since for compatibility with older Photoshop versions you'd have to deliver a more or less standardized format.
    Kind of throws a big monkey wrench into claims that converting to DNG is functionally equivalent to opening raw images directly though...  I was experimenting with a "fall leaves" image last night and no matter what I tried with the 2010 process I was still able to get more detail in bright red leaves with the 2003 process.
    I suppose that says if you want maximum flexibility and control you'd better buy the Photoshop upgrades and stick to opening raw camera files directly.  A variant on the "if you want to play you have to pay" adage.

    P.S., Does the DNG converter read the centralized database as well as XMP files?  I personally prefer the database to the extra files.

  • Do I need to keep my xmp files after converting my raw files to dng?

    I originally set up Lr to automatically build xmp files.  Recently, I decided to go with dng files and have converted all my raw files to dng.  Can I now delete all my xmp files and change my Lr setting so xmp files are no longer automatically produced?

    WDKlein1000 wrote:
    I think I've got this straight.  My goal is to keep the xmp data with the image file (embedded into the file in the case of dng files) as well as in the Lr catalog.  I still need to auto (or manually) save xmp files in order for Lr to save the xmp data internally to the dng file.  Right?
    Perfectly right.
    WDKlein1000 wrote:
    I've been converting to dng after I have done my initial Lr processing of the raw files and the sidecar files have already been produced.  When I convert to dng, the side car files aren't automatically deleted.
    I *think* if you say: do not delete previous raw, it keeps both xmp and original raw files. However, if you say: delete original raws upon conversion, it will delete both raw files and xmp sidecars. In other words, they are treated as a unit. So I suspect your raw files are not being deleted either, right? Note: if this is the case, then whenever you sync your folders, it's gonna wanna pull in all the original raws again. If it were me, rather than deleteing the xmp and leaving the sibling raws, I'd move both to a backup.
    WDKlein1000 wrote:
    I wonder if the sidecar files would ever be produced if I imported with the option to convert to dng and then wouldn't ever be editting the raw files?
    They would not. If you know you are going to prefer DNG, it seems prudent to convert upon import.
    WDKlein1000 wrote:
    I know the sidecar files are relatively small, but I guess it wouldn't hurt to go back and delete them once the xmp data is embeded in the dng files.  Right?
    Right again - delete away...

  • Question about converting my RAW files to DNG

    I've shot with Nikon, Olympus, and Panasonic so I'm familiar with all their proprietary RAW formats that each uses. I'd like to convert all my RAW files to DNG and then use that on import into LR going forward. I noticed that the DNG files from the Panasonic or Olympus images don't display a thumbnail in my finder folders (Mac OS X) so I tried some experiments.
    I used the "convert to DNG" function in LR for some RAW files from each of the 3 cameras. Only the images taken with the Nikon D5300 show a thumbnail image in my finder folder. The Oly and Panny shots only display the DNG icon. Next I used the "export to DNG" function thinking that might make the thumbnail available but it was just the same. I would like to be able to see the images in my finder folders and also be able to open them to view in "preview" but only the Nikon converted DNGs will open in preview and not the Panny or Oly DNGs. Am I doing something wrong in the preferences? I've attached a screen shot of my preferences settings for DNG in LR and the thumbs that I'm seeing in my finder folders.
    These are the settings I have set in preferences in LR
    This is my Nikon NEF image converted to DNG    and my Panasonic RAW image converted to DNG (same thing happens with Olympus ORF files)  

    I probably missed this detail in what you’ve posted, but do you see the thumbnails of the three cameras’ raw files in Finder if you don’t convert to DNG?
    What has happened in the past is that the Apple raw interpreter doesn’t read thumbnails of DNGs it doesn’t like, where at least one thing it didn’t used to like was embedded lens corrections for mirrorless cameras.  Are the Olympus and Panasonic mirrorless—meaning there is no optical viewfinder and everything is seen on an LCD screen or perhaps an electronic view finder?  If so the reason these are different is that the camera is doing the lens distortion corrections automatically and this information is stored in the raw files and in the DNGs but Apple doesn’t know how to use these embedded lens corrections or doesn’t know how to read the newer DNG spec that does allow for this information to be embedded in the DNG, at least.
    Apple could just extract the embedded jpg preview and ignore the other parts of the file it doesn’t understand, but it apparently doesn’t do this.
    What I’m not sure about is if the Apple raw interpreter still has this problem or if you’re on an older system without the latest updates for camera raw decoding by Apple.

  • Converting Nikon NEF files to DNG without adding Chromatic Aberrations?

    Used Adobe converter 7.4.0.137 and got Cyan and Magenta abberations on all high contrast edges. NEF files were from a Nikon D7100 and look great using ViewNX 2 software. Is there a better converter?

    The DNG Converter embeds a thumbnail and preview in the DNG that are rendered with whatever the Camera Raw defaults are set to do for the camera the DNGs are from, which if CA is automatically being removed by default, then the preview should have it removed, otherwise it won't.  Again, we'd need to understand what Adobe defaults are in effect for the camera when the DNGs are opened in the Camera Raw plug-in before understanding if this is a CA-no-on-by-default issue or a CA is not the type that can be corrected by the Adobe engine.
    The Nikon engine might easily be masking narrow fringes of color by over-aggressive sharpening or via some automatic fringe-removal.
    If the OP would post an example photo that exhibits the fringing, then others could test and comment on what can be done or not done to mitigate the issue in Adobe products.

  • I have converted some NEF files to DNG without compression but the conversion were performed WITH compression!

    How to avoid it?
    Bernard

    As LR5user correctly notes, dng ALWAYS uses compression. You can only choose whether you want lossy compression or lossless compression. If you did not check the lossy compression checkbox, it will use a lossless algorithm. You do NOT want to avoid this as you are only wasting disk space if you don't use that compression. There is no loss of information. You should end up with files that are somewhat smaller than native raw files as the compression is somewhat more efficient than what camera makers use in their cameras in general.

  • Can't convert CR2 files with DNG converter

    After buying the Canon T2i, I realized that the files (CR2) won't open in PS.  I did my research and found that the dng converter was the thing I need.  Unfortunately, the converter won't recognize and convert the CR2 files that I try to convert.
    I am guessing I will probably get a reply telling me I should have done my research before I bought the camera (as I have seen in other forums), but I am hoping for a more productive (and less offensive) answer.  
    Thanks!

    I see a lot of answers speaking about having the most up to date version of the Camera RAW Plug-in. I have a similar issue with my .CR2 files... I cannot open them in Camera RAW because it tells me that my camera model or make is not supported by the Plug-in, and so I was directed by other forums to just try converting the .CR2 files to .DNG. I already had the Adobe DNG Converter (version 6.5 I believe), so I tried this. It too told me that my files or camera make were not supported. However, I have always been able to successfully both open my .CR2 files AND convert them to .DNG. I had not updated anything on my camera nor on my Adobe programs and for some reason this last attempt to open RAW files failed me... I have no idea what change would have led to it. Luckily I shopt in both RAW and Large JPG but I certainly don't want to rely on my JPGs of course... Any idea why this problem might have arisen now if it had always worked easily in the past?
    Thanks!

  • I can't open most files from DNG Converter 5.5b (Olympus E-P1)

    I have a bunch of E-P1 photos taken in RAW (.ORF files) and was waiting eagerly for support by ACR. I tried the DNG Converter 5.5b today and converted all my images to DNG.
    When I tried to import the DNGs in iPhoto, it imported only 32 files out of 800.
    These 32 images also have a proper icon (with the preview of the photo).
    I can't open the others with either iPhoto, QuickLook or Preview.app
    All DNGs were opened successfully with Photoshop CS4 or Lightroom once I updated ACR to 5.5b
    It seems that, for some reason, Apple apps can't open this "new breed" of DNG files.
    Does anybody have the same problem ?

    David, I'm afraid you will probably have to follow up with Apple on this
    one. (If I'm understanding your post correctly, you have no trouble using
    Adobe software to process the E-P1 files.)
    Eric
    Sorry, I updated my original post because I realized I wasn't making much
    sense !
    The DNG Converter did convert all my files to .DNG
    I can open all of them in Photoshop CS4 (or Lightroom).
    But I can only open a few of them with Preview.app, iPhoto.app or QuickLook on
    Mac OSX.
    I found out that the one I am not able to open are the photos taken with the
    kit lens (Olympus 14-42mm).
    The ones I shot with my Voigtlander 35mm 1.4 ( + adapter) were imported
    successfully in iPhoto.

  • Filter in adobe bridge to only select Raw files for DNG conversion

    Here's my problem - I have a new DMC TZ70 camera and Lightroom 5.7 doesn't recognise the .RW2 files. I would need to buy LR6! Perhaps later.
    So I thought I will import via bridge and convert to DNG.
    So I open bridge and select the camera - fine - BUT there are files for the Raw images, the same number of JPEGs and some .bdm, .TDT etc files. (e.g. 3 raw + 7 others).
    I can set up a filter to view only the Raw files when I see what files are there in the card folder in Bridge but when I select "get photos from camera" I can either select them all OR deselect and then I need to MANUALLY select the raw files. There doesn't seem to be a way of setting up a filter in the Downloader screen so that Bridge only selects the Raw files for conversion.
    If I let it select all, Bridge converts the RW2 files to DNG but also brings in the jpgs and other files. I can delete these afterwards but this seems an inefficient way to do it.
    Is there any way to manually select the raw files in the photo downloader screen?
    Advice please, thanks, Mel

    Not sure I follow completely, Mel, but Bridge allows you  to View > Sort > Type... which would allow you, after sorting, to click on the first image with a specific extension, then hold down the Shift key to select the last in  the series and  handle them independent of the other files presented.
