Convert to DNG after Lightroom adjustments

Hello,
I have a number of CR2 (RAW) files that I have made adjustments to in Lightroom. I would like to use the DNG Converter (standalone) to convert to DNG.
Usually, I convert to DNG before making adjustments...will my adjustments to the CR2 files be applied to the DNGs after conversion (outside of Lightroom using DNG Converter)?
Thank you
PS: Under what circumstances is it necessary to embed the Raw file in the DNG?

YTou don't want to use the dng converter. If you use DNG converter, you will lose all your adjustments and Lightroom will lose track of your files. Just use Lightroom to do the dng conversion. That will make sure the changes are kept and you will not lose the link in Lightroom. The option is in the Library menu. There is no difference in the generated dng file, so it is far more convenient to do it in Lightroom.
> PS: Under what circumstances is it necessary to embed the Raw file in the DNG?
Never. My advice is to if you really want to use dng (there are a few good reasons to do it, one is reduced file size, but also a lot of good reasons against it), to back up the original RAW files first in a separate location if you don't already have a backup. You might need the RAW file later. If you embed the RAW file in the CR2, you end up with very large files (about double the size of the original file), which completely negates the filesize advantage of dng, which is without embedded raw about 10-25%. You will be able to extract the RAW files later if need arises though which might be convenient but absolutely not necessary.

Convert to DNG after import?

Is anyone aware of a good way (workflow, applescript, plugin?) to convert raw files to DNG after they're already in Aperture? In other words, is there a way--like Lightroom--to convert the files but otherwise preserve adjustments, versions, and other meta-data?

if the DNG file could not be displayed in Aperture, it means that the original RAW file format wasn't supported. IIRC, there are two types of RAW files, those that serve as a wrapper around the original RAW file and a "linearalized" format, where the DNG converter attempts to convert the manufacturer specific RAW data into DNG image data. Aperture doesn't support the linearalized format for sure and Aperture only supports DNG wrappers for file formats it supports natively.
at this point i think that advocating DNG conversion on a broad scale is a bit premature. even after several years of promotion by adobe, there is still no industry-wide adoption of the format. camera manufacturers need to start writing DNG right to the storage cards, then it will begin to become a true standard.

Converting to DNG after editing.

Is there any way to convert raw files to DNG after they have been edited and preserve all the edits in DNG?
I have to say I never converted anything to DNG before. I just tried to convert a few files and all the edits have been discarded.

Yes, just use the Library menu command to convert to DNG.
LR keeps the same development and other metadata instructions as it had for the proprietary raw image.
If you want to this outside LR, you need to save it to xmp, so do a ctrl s after the conversion.
What exactly did you lok at when you said the edits had been discarded?

Can I convert to DNG after I have edited all my original Raw files in Lightroom?

I'm asking because i've become convinced to use DNG's instead of NEF's and RW2's from my Nikon and Panasonic cameras. My main reason is future compatibility.
I have already edited all my NEF's & RW2's from the past 2 years in their native file format in Lightroom 4. Is it still ok to convert them to DNG now (even though they have been already edited (non-destructively of course)).
Thanks.
Also, why can't Windows Explorer show thumbnail previews of DNG's on my Windows 8.1 64bit Pc. I assume is has something to do with not having the DNG codec. However, on Adobe's website it says their DNG codec only works on Windows 7. Any ideas?
Thanks again.

Yes, you can convert your images to DNG at any time. But are you absolutely sure you want to do that? You won't be able to use any Canon or Nikon software to work on those DNG files if you ever find a need to do that. And I really wonder about the "future compatibility" issue. But the choice is yours, of course.
You will have to do a Google search for a DNG codec. It will have to be installed in order for you to see your DNG content in Windows Explorer. You worry about future compatibility, but you have to be concerned about compatibility now in order to use DNG files.

Converting to dng after the moment

I've just started to convert my 5D RAW files to DNG before importing into Aperture.
However, I have about 1500 images in Aperture which are .cr2 with metadata and adjustments applied. Is there a way to convert these to dng and preserve the changes without reimporting?
Ross

Use the export masters and export with the sidecar file option(under metadata in the export dialog). Just export into a folder and then use the Adobe convertor to convert these files to DNG. The DNG files will contain all the metadata such as keywords. Then import these DNGs into Aperture, Aperture will read the embedded metadata in the DNG and then I believe you can lift and stamp your adjustment settings from the original cr files onto the new DNGs and then if you want to remove the canon files you may.
As you know Aperture does not itself create DNGs from another raw format but once you import a DNG Aperture can export it as a master and embed any metadata into that DNG upon export. Remember that if you export a master that is not a DNG, if you choose to include metadata, use the sidecar option. An application such as Adobe Bridge will read the exported raw files sidecar to see its metadata.

Is it wise to keep the Nikon camera files "DSC's" after downloading them and converting to DNG files via Adobe converter for lightroom use. In other words do the DNG files have all the raw data I would ever need in processing or should I save the camera'

Is it wise to keep the Nikon camera files "DSC's" after downloading them and converting to DNG files via Adobe converter for lightroom use. In other words do the DNG files have all the raw data I would ever need in processing or should I save the camera's DSC files?

DNG files do not contain some metadata supplied by the camera, which can be used by the manufacturer's software. Thus, if you don't keep the original Raw photo, you will lose this information.
If your 1000% sure you're never going to use the manufacturer's software, then this isn't a problem. But who can be sure what software you will be using 10 years from now?

Are adjustments retained after Convert to DNG?

I have a lot of NEF images to which I have already applied image adjustments. I would like to convert these to DNG.
1. Will my adjustments be carried forward to the DNG files?
2. If so, will they have exactly teh same affect when applied to the DNG files as to the NEF files - i.e. will the final adjusted images look exactly the same?
Thanks,
Charlie

1. Yes. The adjustments are stored inside the Lightroom database, not in the original files. Sometimes a copy of the adjustements will be stored in the file's metadata or in a xmp sidecar, but only when you turned that on. That file is not used by Lightroom but only by other Adobe programs when you directly access the images from them.
2. Yes, a dng is simply the RAW file stored in a different container. By converting to dng, you gain some degree of convenience in Adobe programs, but it really does not matter one bit if all you use is Lightroom or only call Photoshop from within Lightroom. Dng files are usually slightly more compact than original RAWs due to a slightly more efficient (and slightly slower) compression algorithm used in them. You do lose ALL compatibility with manufacturer sodtware (i.e. capture NX, Canon DPP, etc.). They do not read DNG files at all. So think deeply before you do this and my advise is that if you go the dng route is to backup the original RAW files somewhere before converting. You should be backing them up anyway.

Converting files to dng after import

Hi. Brand-new Lightroom 5 user here. I don't remember the dialog box showing up to ask me at the time of import whether I wanted the pics imported as dng files or not. Now that they're imported, is there a way to tell if they are already dng? I also know how to convert them one at a time, but is there a way to just have them all converted at once? (There are a few hundred.) Also I'm being asked whether I want to only convert RAW files (I'm guessing that this is the case, but let me know if I'm wrong here). And if I want to delete originals after conversion (again, I think I do, but is there a compelling reason not to delete? Can you tell I'm not a professional photographer?)
Thanks much for your help.

See screen capture.

When you have one of the files selected the .dng extention will be displayed.
I also know how to convert them one at a time, but is there a way to just have them all converted at once? (There are a few hundred.)
Sellect the files in the grid view Library module and use the Library menu to select "convert to dng" see the screen capture.
Also I'm being asked whether I want to only convert RAW files (I'm guessing that this is the case, but let me know if I'm wrong here).
There is really little benefit in converting jpeg or tiff files to dng.
And if I want to delete originals after conversion (again, I think I do, but is there a compelling reason not to delete?
If you are using only Adobe products then you may never have use for the original raw files. However your camera manufacturers software and some other raw conversion software will not work with dng files. I am not a user of dng so my opinion is to always retain a copy of your raw files.
My main reason for shooting raw is to retain the original data for the benefit of utilizing further advancements in raw conversion software in the future, including software that does not support dng files.
Can you tell I'm not a professional photographer?)
No, as far as I am concerned there are many professionals and amateurs that may not know the answers to your questions.

Nikon D810 .NEF (small) files converted by DNG Comverter 8.6 is not recognised by Lightroom 5.5 or CameraRaw 8.6

D810 NEF (small) files converted by DNG Comverter 8.6 is not recognised by Lightroom 5.5 or CameraRaw 8.6. The normal NEF files are visible after conversion. Is there a way out to get the converted DNGs read in LR or ACR?

No there is not, but as of yesterday, Adobe knows that the 9MP small-raw files don’t work and will likely fix in the final release. Until then you need to shoot full-res 36MP images.

How do I convert multiple full sized DNGs to lossy DNGs within Lightroom?

Hi,
When I select multiple DNGs from within Lightroom, and on my mac go to menu>Library>Convert photo to DNG and then choose to convert to DNG with the lossy mode selected, only one of the selected DNGs is converted. How do I convert more at the same time? I have a large library, and I want to convert ~100gb of photos to lossy.
Thanks in Advance!

As far as my own collection goes, I would say I love about 1-2% of my pictures. I would like to use the top 5% for making printed family albums, and I use Lightroom to develop these images. The next 5-10% I would partially process and keep somewhere online at lower resolution, like on flickr. The next 20-40% I would like to keep around in storage, and the rest I trash.
These last 20-40% that I want to keep would be fine as lossy DNGs. I would treat them as JPEGs that have a bit more dynamic range for the future, but as I shoot with a 24mp Nex-7, they are huge, and won't ever be pixel-peeped. I have examined the difference between my 25mb DNGs and the converted 7mb lossy DNGs, and for my uses, they are functionally identical.
The issue is that I need to import them into Lightroom before I rate them. Once I rate my images, I flag the ones I want to work on further, and delete the worst. I would like a way to convert the remaining ones more easily. Of course if I knew which ones were 2nd-rate keepers from the outset, I would import them as lossy DNGs to start with.
I often have 3-4000 images to process after a holiday, so I need a fast method of compressing these DNGs.

How can I safely convert CR2 files to DNG after Import from catalog

Images on my laptop from 2 photoshoots in the studio today were EXPORTED from laptop as catlog and imported to desktop as catalog.
I imported without moving the files anywhere since I was instructed to move that folder to its final resting place.
The 125 images were importred into LR4 but I see they are still CR2 files.
Is there a way to convert these guys to DNG inplace? or is it safe to re-import these. I don't want the side car gig.

Convert to DNG (Library Menu) - do not re-import.

How do I convert to DNG for CS3 without demosaicing?

Recently purchased the Sigma 60mm 2.8 lens for my Sony NEX-6, which shoots ARW raw files. When converting to DNG (using the newest 8.2.0.94 version), the files increase in size from ~15MB to ~60MB. This appears to be because I have the compatibility settings set to Camera Raw 4.6 compatibility, and the converter believes this means it has to demosaic the image. This is done with no override and no warning that information is going to be discarded, despite the fact that I shoot raw files because I want raw data. How can I produce DNG files compatible with Photoshop CS3 and Camera Raw 4.6, without discarding data and producing huge files?
This is doubly frustrating since manual lenses convert fine. I do not care about any lens correction information in the original ARW files, as only very minor corrections are needed anyway. Losing this information to produce good DNG files is perfectly acceptable to me.
Similar threads show that newer versions of DNG can be converted to without the demasaicing being applied, but this is not helpful to me. See http://forums.adobe.com/message/4312768, http://forums.adobe.com/message/3333887.
I have no plans to upgrade photoshop (especially the CC versions), so need something that works with CS3.

Okay, so I lied. I'm going to answer one more time. In my opinion, it isn't necessary to change your "entire workflow". Take the example of a panorama image. As in ACR, I make adjustments to the raw images using Lightroom. Of course, I have imported those images so I'm able to see that folder of images in my Lightroom library. Lightroom has an adjustment where I can highlight all images and choose to "match total exposure". I have found that using that really simplifies the merging to panorama process.
When I have done all that I need to do in Lightroom, I highlight all the images and choose the option to merge to panorama. Photoshop opens, the images that I've highlighted transfer to Photoshop and the panorama dialogue appears listing those images. I set my options and let Photoshop build the panorama.
When I'm through with Photoshop I save the panorama image and return to Lightroom. The panorama is there automatically added to the catalog. I can take that image back to Photoshop if needed. And I can export images in different formats for different purposes. But I only have the master images and the one panorama that I have to maintain. If changes are decided upon in the future I only have the one image to worry about.
The postprocessing in Lightroom is much more elegant (in my opinion) than ACR. You know, you can download Lightroom and try it for 30 days and see what you think. I still believe you are anticipating much more change than is really necessary. So my original answer still stands.

Cannot Edit a Copy w/ Lightroom Adjustments in I LR 2

I am using Lightroom 2 w/ Windows Vista. Just recently I found that after I make a few edits in the Develop module and then try to Edit in Photoshop CS3 I no longer get the window offering a choice of options such as "Edit a Copy w/ Lightroom Adjustments". I can't find anything in the Preferences that explains this. Updating to Lightroom 2.1 did not help.

There are numerous threads about this in this forum, but a brief answer is:
You will only get the dialog offering the choices if you edit a non-RAW file, i.e. .jpg, .tif, .psd.
If you edit a .dng, .cr2, .nef, or other RAW file using the primary editor you will not be offered the choice. This is by design.
If you
are editing a non-RAW file and aren't offered the dialog box then you have a problem.

Should I use default Raw or convert to DNG?

Hello,
I have olympus SP570UZ and use LR 3. I'm not a professional photographer but do a lot of photography and shoot in raw. My question is should I use the default raw file for import/editing or should i convert to dng? does it effect editing capabilities and degrade the result when i convert to dng?
I work on laptop and it seems a lot slower in loading default raw files. Will this improve my overall work time and lower load on cpu and space, but my first priority is picture quality?
Thank you.

Converting to DNG is really a matter of choice not necessity. If your camera is already supported by Lightroom / Camera Raw then there is little to be gained by converting the images to DNG at the beginning of your workflow. Many who champion DNG will keep their images in the camera vendors raw format until they've completed their edits and only then convert the final image to DNG.
In answer to other questions. Performance - DNG is not some magic bullet that will increase the performance of your family saloon into that of a Porsche. Space - The lossless compression used by DNG is more efficient than that used by the majority of other raw formats, but only saves space if you trash the originals after conversion. (Note - trashing your original raw files is not something that I would ever recommend let alone suggest.) Quality - There should be no difference in quality between the original raw file and the DNG version.
FWIW, DNG was originally proposed as standard "capture format" but as time has gone by and few camera vendors jumped on board Adobe's position has changed to "DNG is ideal as an archiving format". The latter is probably the less time consuming and more future proof approach. As mentioned above,it's also the approach adopted by many of those who champion the DNG format.
No doubt someone else will come along and add their tuppence worth for one or the other, but if previous threads on the same subject are any guide you'll still be left wondering. Try typing your original question into Google and see the mass of info and opinion that already exists. I can hear the sound of Hornets buzzing already.
Disclosure - I use DNG not raw throughout my workflow. This means that my thumbnails and previews accurately reflect the Adobe rendering in all of the applications "I" use. "I" don't use the camera vendors software (i.e. Canon DPP), so have no issues with the fact that it does not support DNG.

Convert to .DNG at Tethered Capture?

Is it possible that Lightroom V5 can convert to DNG upon ingest of tethered capture images? In other words, when I'm tether shooting, can the image I capture show up in the Library already converted as a .DNG? This would be optimal for my workflow, rather than have to export my native camera raw file as .DNG after the session is completed. Would love to know if this can be accomplished.

Does any know ?
