Converting RAW fies to DNG in Lightroom 2.0

Windows XP SP3, Nvidia graphics, AMD processor
When converting RAW (Nikon) files to DNG in LR2, the process never completes. In LR 1.4 converting one file takes 3 to 4 minutes. I Have let the conversion process run 3 to four hours in LR2 and it does not complete.

Have you tried LR 2.1?

Converting JPEG files to DNG in Lightroom

Is there any advantage to converting JPEG files to DNG when I import them into Lightroom? I am trying to maintain the quality of the file.
Would it be better to save a JPEG file as a PSD file after I import it to use it in Photoshop and Lightroom?

(Please pardon the change of subject:)
Fred T. said, "If you are editing a JPEG in Photoshop going from Lightroom, let Lightroom create a TIFF. "
I am wondering how to do this. I'm just an amateur and my non-SLR camera doesn't even save RAW images. ("Yup, need to take care of that one of these days.")
My Preferences for "External Editors" (in my case Photoshop Elements 4.0) is set as: File Format: TIFF; Color Space: sRGB; Bit Depth: 16 Bits/component; Compression: ZIP.
When I right-click on a file, and choose "Edit in Photoshop Elements 4.0.app", and pick Edit a Copy from the dialog box, the new file that is created and passed over to PE is a .JPG file not a .TIF file.
I get the feeling that the functionality to create a TIFF, or a PSD, only works if my original image is RAW or DNG. But perhaps I am overlooking something???
Life would be a lot easier if I could send the file to PE as a TIFF. At present, as a workaround, I tell LR to edit the original (so it doesn't create a copy), immediately Save-As in PE as a TIFF so I don't overwrite the original, and then when I'm done editing in PE, save the results (still TIFF). Once back in LR, I have to import the new file.
Any Thoughts?

Why is bridge not converting raw images to dng during upload after re-installation even though I have manually selected it to do so?

I have exhausted all options after re-install to get bridge uploader to convert my raw images to dng and need help!

Hi Jeff,
Thanks for following up.
Slowly I am learning about what is going on with my problem. I need to first further clarify my problem for you. I am new to both my iMac and its Version 10 of Photoshop. When I bought the CD set I thought that the term "premiere" referred to both Adobe Photoshop (stills) and Premiere (movies). Now I understand that it only refers to the movies. So, my problem rests with Photoshop. As just mentioned have just acquired my iMac and it does not seem to have a screen shot application. However, would you please take a look at the Tools panel in Photoshop? The icons for the brush tool, the eraser tool, and the smart brush tool all have a tiny black triangle in the lower right corner of the icon. It is my understanding that when I click on the eraser tool and should see three more icons pop up. They do not. So what is wrong? That is the source of my frustration with the product. I can't duplicate some of the instructions that I see in my book.
Again, thank you for your follow up.

Cannot convert RAW files with DNG

I have downloaded the Adobe DNG converter to my Mac OSX 10.4.11 and have tried opening RAW
files from my Canon Powershot G12 and EOS 550D SLR and the converter will not read the files. I have learned from other posts about dropping the folder into the icon but when I do the notice comes up "cannot parse the file." Any ideas out there?

Contrary to what it says there, that is all you need. You DO NOT need to upgrade to Leopard first. You can go straight from Tiger 10.4.11 to Snow Leopard for $29.
CS4 will cease to be upgradeable towards the end of this year, perhaps as early as November of 2012.
The superior rendering in ACR 7.1 is more than worth the cost of the upgrade. You could even say that converting one irreplaceable raw image is worth the total cost.

Try Easy Find first, it's totally free, although Find Any File is indeed faster.

Finally if you still can't get DNG Converter 7.1 to launch, then download version 6.4, but nothing earlier than 6.4:

Converting Raw files to DNG

When I open RAW files in Photoshop CS4, I can save them as a DNG file, however when I try to use the DNG 5.6 converter to do the conversion, it will not recognize the RAW files. According the the Adobe website, the current verion of DNG converter is supposed to recognize my CR2 files, but in it actually does not.

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

I discovered that when I open the Raw files in Photoshop CS4, I can then save it as a DNG file. The DNG converter has a bug in it
When you convert the raw in DNG in the ACR dialog then you are not using the newest DNG converter; you have been using that, which came with your ACR. Start the DNG converter on its own (by double-clicking on the file name,..) or drop a file on its file name with Explorer, and try if that DNG is all right.
Relating the unusable DNG file: can you upload it somewhere? If you don't have web space, use yousendit.com and post the URL for the downloading here (the receiver's and sender's email address may be fictious).

Ok to convert raw xmp to dng?

I am converting a bunch of raws to DNG that have xmp files and I am noticing that the xmp files are being dumped in the trash as well. Should I be concerned? Is this something I should do if I want to conserve space but keep my changes to my old raw files?
Thank you

The XMP information is stored inside the DNG, so it's not a cause for concern. (from your description, you're deleting the Raw files).

Batch convert Raw files to DNG via Library's convert to DNG issue

I have LR 4.4 running on a Win 7 64 bit PC...
I selected 4 RAW files (CR2) to convert to DNG via the Library modules 'convert to DNG' and then delete the CR2 file.
It converted only the last of the 4 files and left the other 3 untouched as CR2 files. Can LR not batch convert the RAW files in this manner??
Dave

I tried again to convert the remaining 3 CR2 files to DNG by selecting the 1st file and shift clicking on the 3rd file in the film strip and then via 'Library-Convert photo to DNG. I have Delete originals after conversion checked.
This time it converted the 1st file and left the other 2 unchanged. It seems to perform the operation on the 1st file selected...the first time when I tried this on the 4 original files I had clicked on the last file and then shift clicked on the first on in the series.
BTW...I have LR4.4, Win 7 64-bit, 16G ram, Pentium 7...
For what it's worth, I also noticed that when I "round-trip" a file to CS6 and then SAVE the file it should bring me back to LR with the new file placed next to the old one in LR. Mine does not. The new file is not shown and I have to synch and add photo's to have it show in LR. Another issue...
Thanks for checking on your end. I suspected LR should properly batch the conversion as it did for you and that I had an issue. With the Nik suite and Perfect Effects 4 installed I'm hoping not to have to do a complete uninstall/reinstall...what a pain (sigh).

Convert raw in dng inside Bridge

I'd like to convert raw files in dng like this:
browse a folder on my hard disk
select the pictures I want to convert
convert them to DNG
but I can't find a way to do this. In LR it can be done.
Any help?

but I can't find a way to do this. In LR it can be done.
Select the files you want to convert and open them in ACR. With multiple files they will appear in filmstripmode. Choose select all and then choose the 'Save Images' Command (bottom left in ACR Window.
From the options for saving choose 'Digital negative and you will see the DNG options appear.
Choose a location and hit OK.

Does converting RAW CR2 + XMP convert both of those into the DNG file, or does it just convert the CR2?

This is a stupid question that somehow, after hours of searching, I can't find a definitive answer for:
I have an existing catalog of photos that are stored in .CR2 (Canon RAW) format, plus accompanying XMP sidecar files on the photos I've edited. If I decide to convert those to DNG, does the conversion process automatically pick up the edits I've done from the XMP files and write those edits into the resulting DNG? Or does the conversion process just convert the CR2 --> DNG only, ignoring the XMP sidecar file?
Stupid question, but a really important one!
Bonus question:
Does the conversion process leave the CR2 and XMP files in the folder as they are, and just add the DNG in addition to those? Or does it delete the source CR2 and XMP files, REPLACING those with the DNG?

Have you run into any really important / crucial ones to your workflow that don't support DNG?
really important / crucial?, to me? - never.
Don't get me wrong: some people *love* the feeling they get when deleting the original proprietary raws - like they're standing up for a cause or something. If you are such a person, then by all means: knock yourself out, and enjoy - nothing terrible is likely to happen (unless Adobe goes under and/or DNG format falls flat..).
I have discovered a surprisingly large number of cases where some (Adobe-converted) DNGs were not readable, e.g.
* Bibble
* CaptureOne
* DxO
(note: original proprietary raws were fine).
All of which purport support for DNG (and likely read out-of-camera DNGs from supported models just fine).
And if you search the forums you can discover more..
(in case Adobe responds (rare): "it's not our fault - programmers must not have read the spec closely enough..". On the other hand, Adobe is sometimes a year or so tardy when it comes to releasing the new spec - hmm.. - I guess turn-about is fair play (Nikon is sometimes tardy with NEF documentation which supports new cameras, forcing Adobe to work without (reverse-engineer) for the mean time..).
Two other software's that don't support DNG:
* Canon's DPP (and other Canon software).
* Nikon's NX2 (and other Nikon software).
If you want to display focus points, proprietary raw is required, period.
Me? If I were to bother to convert raw files to DNG, I would do the opposite of what most people do - instead of archiving the originals and using the DNGs, I'd archive the DNGs and use the originals. That way, I can open my photos in any software I choose, and/or see focus points if I feel like it, but if I get cryogenically frozen for a few decades whilst DNG wins the format war, I'll have the DNGs to use.
To each their own, just realize: DNG is not a standard, yet, and may never be, so you are playing the odds (burning bridges) if you discard originals. Adobe really wants it to be a standard, because it gives them an edge over their competitors (since Adobe controls the spec, and when it's released..), so if you want to help ensure Adobe success in the format war, then by all means: delete your originals.
To be clear: I personally support the DNG format, completely. I just don't convert my existing raws to DNG yet, and generally recommend to others who convert: keep your originals.

Unable to covert raw files to dng?

using photo cs 3 ,unable to convert raw files to dng?

Make sure you have the latest version of ACR for CS3 installed. I seem to remember it was something like ACR 4.6. Check and see if it can save DGN conversions. I don't use DNG format for its not as well supported as manufactures raw formats.
You can always download the latest DNG converter or a version 4 DNG converter http://www.adobe.com/support/downloads/product.jsp?product=106&platform=Windows

Updated Camera list for converting Raw files in PSE7

I am looking to instal an updated CameraRaw.8bi file to accomodate recent cameras.
Camera updated needed for Canon powershot G15.
Regards Daz.

Photoshop Elements 7 supports Adobe Camera Raw from version 4.5 to 5.6 only.
Please refer following document for you reference:
Camera Raw-compatible Adobe applications
http://helpx.adobe.com/x-productkb/global/camera-raw-compatible-applications.html
Canon Powershot G15 starts supported from Adobe Camera Raw version 7.3.
Hereby,raw files from particular camera is not supported in Photoshop Elements 7.0.
However, you can use DNG converter to convert Raw files into DNG and import in CS4 aaplication.
The Digital Negative (DNG) format is Adobe’s proposed standard format for camera raw files. DNG files are useful for archiving camera raw images because they contain the raw camera sensor data and data specifying how the image should look. Camera raw image settings can be stored in DNG files instead of in sidecar XMP files or the camera raw database.

Lightroom mysteriously deleted files after trying to convert RAW to DNG

Running Lightroom 1.3 on the MacPro 10.4.8
Strange thing happened. I had a catlogue of 11,824 photos yesterday.
The catalog was a mix of RAW and dngs and I wanted to convert the remaining RAWs to DNGS.
All photos were in place, no ? marks before I used "Convert photo to DNG" command. In the Convert photo to DNG I had the boxes for Only Convert RAW files, and Delete originals after successful conversion CHECKED.
I realize I may have been asking way too much for the computer to do, and wasn't surprised when nothing happened for about 5 minutes. Finally I got the message that it couldn't convert because the original file could not be found.
After that 2,268 files were missing. And as the day goes on today, and use the program that number is increasing, even when not asking to convert.
I don't think it's a hardware issue. Ran disk utility and all checks out with that. And the deleted files are on 2 different drives.
Any suggestions? Thanks!

First step I'd check and find the actual images, make note of their file paths. I'd be surprised if any file was truly missing; just that LR has lost the path for whatever reason.
Second, I'd do the conversion on a much smaller scale- in my case, my workflow is such that I choose to convert to DNG when most or all of my work on a folder is done. So I do it pretty much by folder, which generally don't exceed a few hundred images.

Nikon D5500 generates RAW files as .NEF which Lightroom 5 won't read. How can I convert these on a Mac with Yosemite?

I have tried the Adobe DNG converter (v8.7.1.311) but when I choose the folder where the photos are, it shows an error reading "The source folder does not contain any supported camera raw files". I cannot find any other software for Mac which claims to be able to do this. Can anyone help?

Many thanks for that. I've never shot RAW before and am new to DSLRs generally so don't know the relative difference between formats. If I have to convert RAW to TIFF to be able to use Lightroom, will it have been worth me shooting in RAW at all, or will I do just as well staying with the highest quality of JPEG I can get from the camera? My camera is 24.2M megapixels

How to batch convert RAW to JPG in Lightroom?

Hi. I want to convert a large portion of my older RAW files to JPG, to free up some hard drive space. Is there a way to do that in Lightroom (or perhaps Bridge)?
Thanks for any help.

Export as jpg, checking add to catalog and then delete the originals. This will be a mistake. Keep your original files or you will regret it one day. If you need to save space that badly then convert the Raw files to DNG.

Converting RAW to DNG! What are the advantages / disadvantages?

I have Canon cameras and shoot RAW, but the question itself is surely also valid for Nikon, Sony or other brand-shooters.
When importing my pictures to Lightroom, I could convert them to DNG but didn't do this up to now, because I do not know what I loose. I suppose that I loose the ability to process my files with DPP, but I will not do that anyhow. I can appreciate the advantage of having the file in an open documented format, where even I could easily write a reader for it. So the answer should not be what I can easily find in the Adobe introduction into DNG. I have also the DNG specification in front of me, and I can read it, because I once wrote a program to read TIFF files. I understand that I could add the original RAW image stream, but I do not want using up the space wasted for this. I know, that all development parameters used for the specific RAW image can be written with the image file instead of having those stored in a database or a side-car-file.
But what I did not find until now a technical explanation about what happens during the convert. Who can enlighten me? Where do I find the missing technical explanations?
Thanks in advance!
Lucien.

That wasn't the question... .
Based on the title of the thread and your initial post, it seems like your question had a lot of
"What are the advantages / disadvantages?"
in it, and only a little
"What happens at a technical level when converting"
But if you want more detailed info about conversion, and you have the aptitude to understand, I recommend doing what Lr5user-pt recommended:
Download the DNG SDK and dig in - all your questions will be answered (and if not, you can also ask DNG-specific technical questions in the DNG forum).
As far as my "sources" regarding the technical summary I presented, they are many and varied, none of which are the DNG SDK. In other words, my knowledge is based more on experience over the years - I don't know all the details under the hood..
Some experiments to consider doing:
* exiftool (-X) a proprietary raw file, then convert to DNG and repeat.
* open a proprietary raw in a DNG-supporting software of your choice and inspect metadata, then open the converted DNG in the same software and re-evaluate. Compare to proprietary raw opened in manufacturer's software, and what you see via exiftool.
Tom Hogarty (Lightroom project manager) and others who know have said: "DNG converter discards no metadata", and I believe them, but haven't verified for myself. Yet once proprietary metadata is in the DNG, most (all?) software will no longer decode it. A prime example is focus points - presumably they're there, but once converted, focus point feature is no longer supported. The amount of work required to support converted focus point data is unknown (to me), but as far as I know, no software has ventured to do it. If you want focus points, don't convert.
If you want the truth, I think for most people it's "not wise" to convert to DNG. Why? because unless you already know why you are converting (and need to convert to satisfy your goals), or you already know why you must NOT convert (e.g. so you can open the files in mfr.software, and see focus points..) the pros and cons are likely to be a wash, and now you have twice the number of raw files, unless you discard your originals, which would be REALLY "not wise", in my opinion. If you find the notion of "openly documented format" sufficiently compelling, then, ya know, more power to ya (I don't judge..), but there is no guarantee that DNG will outlast NEF (or..), and if it does, there will be ample opportunity to convert before you're left in the cold, unless you're stuck in a cave for a few decades, or are kryogenically frozen.. True, if all companies die, you may be able to write your own DNG converter (/reader), given the DNG documentation, but FWIW, NEF is also thoroughly documented (document is in freely downloadable SDK), and reverse engineerable (that's what Adobe and Phil Harvey does), so you could also write your own NEF converter, so not really a very compelling argument, not this year anyway - ask me again in a few decades..
If filesize is a main draw, then be sure NOT to save the hi-rez previews in your DNGs, otherwise you've just lost most or all of the filesize advantage. Also, you can strip previews from some proprietary raws (e.g. NEFs), to reduce filesize.
Personally, if DNG supported sidecars, I would be more likely to convert, because file-management/backup is only an issue if you "forget" about xmp sidecars (and I do not forget), and I'd rather have my xmp in separate ready-to-read xml text files, rather than embedded in binary files, but hey, that's me..
PS - I always use/encourage-others-to-use DNG when distributing raws to others for use in Adobe software, so xmp is not separate and can not get lost.
PPS - proprietary raws and dngs are both just glorified tiff files - raw data, previews, and metadata..
Don't get me wrong: I am NOT anti-DNG, and in fact - just the opposite: I am PRO dng, it's just that I wouldn't (don't) convert my own raws to DNG at this point. If you find the reasons to convert now are sufficiently compelling, you have my complete support and cooperation, fwiw..
Cheers,
Rob
