Convert JPG & Delete DNG DNG?

Hello

I have a lot of old photos that I won't have to keep files DNG (converted from the NAVE). I'd rather have a JPG file (or DNG format which does not contain RAW data, leaving only JPG) for space saving purposes. Is there a way I can do this in just a few clicks of button on an important band in my library?

If I were you, I would like to convert to DNG format with loss: compression bulky like jpeg, but with change in the benefits of raw.

To do this, check the "use lossy Compression" box in the dng conversion dialog prompt:

  • JPG to DNG?

    Is there an advantage to convert jpg to DNG. I know it will not improve the quality of the image and the size of the file increases. But is there something that would improve, as the ability to edit? Or is it just a wash and Don ' t bother?

    Thank you

    DNG provides a container against future degradation. As tiff (or avi video), the container provides greater protection that a witch original jpeg can be degraded by edition or simple rotation.

    I don't think it's true. Based on the changes and where.

    If you create parametric montages, in LR or ACR, you're just incorporating these instructions in the container; JPEG or TIFF or DNG.

    Now, if you apply the changes pixel based in Photoshop, of course.

    If you create parametric edits in ACR or LR, the changes do not appear in the JPEG format until you make that in a new iteration and then Yes, the JPEG changes are applied to the data and Yes, you will undergo a degradation.

    Open a JPEG file in ACR for example, apply an editing tool and click on "fact." You do not see Edit in Photoshop proper. They exist in the container JPEG as edit a TIFF in the same way. This once again, but instead of 'done' click on 'Open' which tells ACR, show changes in the pixels. You see the fixtures in good PS and the damage is done virtually, not. The changes have been applied to the pixels.

    What writes John (The advantage is that DNG prevents any possibility of opening a jpg in Photoshop and saving your changes back to the original.) kind of proves.

  • Lightroom Import convert NEF to DNG

    When I try to import RAW files into Lightroom, they convert to DNG, even if I checked dng converted icon. I removed and tried to reimport after turning power on and off computer! Anyone know what is happening? @

    If you use Lightroom CC or Lightroom 6, are leave you enough time for Lightroom to convert? Lightroom is important firstly the original raw images, and then converts it to DNG in the background. This is to allow you to start working on the files DNG, while the rest are converted.

  • Convert scan slide .dng files?

    We the masses of old slides scanning scans and their import in Lightroom as .tiffs.  Recently, I was told that if I convert these .tiff .dng files that would improve development operations in the develop module and almost to simulate working with a RAW file.

    Does anyone have any experience with this process?  And any thoughts on it?

  • convert jpg, dng

    I have 95 dng photos I want to convert it to jpg. Is there an easier way instead to open each photo in PS, then saving it as a jpg file?

    If you use Lightroom, you can use it to export as a jpeg at the same time! You can still use the trial version if not to do.

  • Convert JPG without losing the settings of DNG

    I have Photoshop elements 13.

    I edit a raw file (.) CR2) in the RAW editor and create superb adaptations to my raw photo.

    I then click on the 'Save the Image' button and the only option to save the file as, is to "DNG".

    I want to save the file as a JPG file but elements, this isn't an option, then, how to convert a DNG file in a JPG file without losing the settings as in the raw file, I did?

    Because you say that the JPG seems strong in the PES Editor, I think that what is happening is that there is a sharpness artificial in the editor because of resampling algorithm if you are not 100% zoom / 1:1 or more, so what you think is the sharpness of your photo isn't really there , and these other methods look at one show what is really there.

    The only way around this is to make your sharpening to 100% / 1:1 zoom and make your comparison sharpness in other viewers to 100% as well so you're not at the mercy of their resampling algorithms that will only be approximate and can artificially boost or reduce the sharpness.

    If you think that this is not how you feel then please provide a screenshot by-side of the JPG in the editor of PES and the JPG in IE or Windows, all TWO ZOOM Photo Viewer to 100%.

  • Converted library to DNG now what about the other files?

    Just, I crossed the step and converted all my images CR2 to DNG, replacing the originals.

    However, I have always all sidecar JPEG files left over. Can I safely delete these, or are they held by the DNG?

    Also, I was using before the option to write the XMP sidecar files. With DNG is there any real need to continue to do this?

    Thank you

    Thanks for your reply. I guess what I'm wondering really is: if I now go ahead and delete these files, .xmp and .jpg, will I have problems in Lightroom? In other words, Lightroom will take care, if these files are missing?

    Lightroom won't care. If you made adjustments to the RAW outside LR, those who are saved in the file .xmp. You should have read the metadata of the file in order to bring them into the LR catalog. But now that the orginal FIRST disappeared, I don't think that it works now in any case (it's worth a shot if you must, however). Now, if you did all your editing in LR than to go ahead and delete the JPEG and xmp files.

    As for your other question, you can always write metadata to the file, but with DNG, metadata are embedded in the dng itself and not a separate xmp file. You never had to write metadata in the file, though.  This info has been and is in the catalog/preview files. In doing so, just allows you to make this info in other applications.

  • Convert with new DNG Converter?

    If I converted a bunch of Canon 7 d CR2 files to DNG using the DNG Converter 5.5 format, should I convert from the original raw file with 5.6? What is different about the files, because the raw data must remain unchanged?

    I thought that the advantage of using raw/DNG was that the file itself is intact and that, as of the raw processing algorithms to improve over time, the data could be "crunched" of ways to improve the image. I'm getting a sense now that some of my DNG files created using older versions of the DNG Converter (I was using DNG for several years now) are somewhat lower than those created using the latest version of the converter.

    Any information on this is greatly appreciated!

    function() {return A.apply (null, [this] .concat ($A (arguments)))}

    I don't have the original CR2s but say I had several DNG files created with 5.5 and then diverted with 5.6; Since it is DNG to DNG, metadata 5.5 (lower) original are preserved. It makes feel me as if I had files permanently "altered" because they were created with 5.5 (although always, I have the original CR2s and could convert originals) and I'm still stuck with what I have

    The current DNG Converter works this way, i.e. it does not replace these metadata (see thread of Barry Pearson, asking for an option to replace the metadata). So, you would be stuck with incorrect metadata if you had not kept the CR2s.

    Note that there is no disadvantage of startiing outside of the CR2, because the settings saved in the DNG file are not very useful even when the changes. For example, the color information has changed; I don't know what size do the changes, but they may require adjustment of saturation and maybe same WB. If you have ISO 100 shots (or 125, 250, 500, 1000 - but you should not use franctional ISOs with raw), then the image will become clearer after the conversion again, so your exposure, filling, brightness, recovery of parameters may have to be changed.

    function() {return A.apply (null, [this] .concat ($A (arguments)))}

    I have lower quality images of 5.5 as 5.6 DNG DNG?

    Yes, but it is a specialty of the support too fast and dirty 5.5 7, i.e., is not a generic account.

    function() {return A.apply (null, [this] .concat ($A (arguments)))}

    I'd be more concerned to make the last ACR/LR and not worry so much about the DNG Converter version that was used to convert to DNG?

    I have no idea if ACR 5.6 has functional improvements over 5.5. However, the correct support of the 7 d raw to DNG files do not require the cab, but the DNG Converter 5.6.

    For example, one of the problems with preliminary support is the labyrinthine appearance on smooth surfaces at low ISO shots. The reason is a hardware failure (clear: Canon created shit). This problem can be countered at least partly (I don't know if it disappears completely) with the addition of a some metadata to instruct the raw processor to apply a somewhat different treatment than normally. It's nothing new, that do still much older versions of the ACR - if the DNG Converter inserted this information.

    (The vertical in the shadows even strips from 100 to 400 ISO do not change, like http: / / www.panopeeper.com/Canon/Canon7D_Banding_ISO00100_Jehuty_DPR_0014.JPG)

    function() {return A.apply (null, [this] .concat ($A (arguments)))}

    I'm just nervous because I do not keep the original CR2s in the long term, only the DNG format. I want to assure you that the DNG, I created with 5.5 is not somehow inferior quality before I delete the CR2s. If there is less metadata in DNG 5.5, will use the latest version of ACR when it comes out 'clean up' these bad metadata for better methods of treatment, or is the only way to 'clean up' metadata to convert to DNG with the official version of the DNG 5.6 converter?

    As you have no way to ensure that the conversion is perfect, it is stupid to delete the original, i.e. the CR2. the rest is speculation.

    However, you should not rule out the possibility that another raw processor or another DNG Converter (or a later version of the Adobe's DNG Converter) can make a better treatment of the CR2 or a better conversion to DNG.

  • Convert tiff to DNG for the option validate

    Hello

    I like the idea to be able to post my photos to avoid problems as little rot when if you use dng format. During the conversion of the library, I would like to convert the tiff files that I have too for the same reasons.

    Is there a reason any I can do to my entire library?

    How manages the conversion layers? I should flatten the TIFF that contain them?

    Thank you

    You lose the layers, stick with TIFF! DNG is a large format, but use it to raw data.

    There are other tools that you can use to validate files for bit rot and other.

  • problem when importing jpg and dng files?

    Hello..

    I take all my photos in the first two and... and so far Lr jpg format would be ideally located both the peak of flood and the jpg one after the other, but lately Lr first puts all jpg files and halfway through all the DNG... does someone knows why this might be happening?

  • How can I me LR6 import to convert my ARW .dng files?

    Hi people,

    Is it possible that I can implement LR6 automatically convert my raw files to .dng when importing?

    I thought that there was once a setting in LR, but I can't.

    For any help or suggestion would be appreciated.

    Not right now I'm at work, but it's not rocket science. Set up the import dialog box as you like, including the exemplary use DNG, then at the bottom, where it says nothing next to "Import Preset", click on the Word no and choose "save settings as a new Preset. Give it a name. Lightroom will recall the settings until you change them.

    Since CC 2015 my LR converts all my NEF RAW-files into DNG. I don't want that! I tried changing the settings - without success. Someone help me please!

    When and how are they converted to DNG?  If it's during the import out of the SD card, remember to choose 'Copy' rather than 'Copy as DNG' during the import.

  • How to convert JPG more than 1 JPG (forWEB) in batch

    Hello

    How to convert more than 1 JPG to > > > > JPG (forWEB) in batch... .use PS CS6.

    First, you define an action for save for Web, like this. You need not necessarily all of these steps, some of them can be done in the SFW dialog box (and note I have nested further action in this one):

    The important element here is the last two steps. You save them in the folder in the SFW dialog box, which is recorded in the action as an export. This is a copy of the original. You don't do any saves anywhere else, just save for Web. Then you close the original unmodified file as the final step.

    Then call the file > Automate > batch. Choose the action, choose the file source and the destination to zero value. It's important! It simply returns the original in the original unmodified folder, while save for Web saves a copy to your destination.

    There are other ways to do this - the procedure here land finished in a dedicated and fixed web export folder files, and I download it from there.
