NEF vs DNG

Ok, Im an amateur photographer, mostly do my work in LR and go to Photoshop
to fix the things that I cant in LR, like work with layers, etc...
However, my PS does not read the NEF files from my D5000 (regardless of how
many times I upgrade Camara Raw), but it reads the DNGs just perfect with
Camera Raw and everything.
So, I guess what I want to know is if there is any loss of information if I where
to convert all my files from my camera into a DNG using LR and disposing of the
original RAW files?
Do the formats look the same? Is the quality just as good?

System or program crashes when converting from NEF to DNG

Hello Adobe.
First off, I love your software.
Second, this is my concern. You guys are pushing DNG as the go to raw format. That would be great if it worked good, but it doesn't.
First, when I convert from my Nikon NEF format (Nikon D7100) it chugs along just fine, then suddenly crashes either the program or my system after converting 50-100 or so images.
I have tried everything from downloading your software again, to turning off everything other then what is needed to do the conversion.
Of course I have the latest DNG utility/plug in/drivers from your website.
Second, the DNG images open much slower then my NEF images. Plus when I view them in Windoze file system view and want to see the photos in extra large icons, it renders the images very slowly.
My system is Windoze 8.1 updated always, Photoshop CC latest and greatest (I'm in the rental program), Bridge and Lightroom.
I have tried to use bridge and lightroom to do the conversion, even a separate utility and the crashing still happens. All these are up to date.
My system has an i7 Intel processor, 16 gb of Kingston ram, an ASUS P8Z77 MPRO mother board and a good stable power supply.
No other software crashes my system like converting from NEF to DNG.
What I do notice is my CPU fan goes into high RPM's and I am wondering if the CPU is overheating causing this.
If that is the case, then it would seem to me the conversion software is taxing the system far more then it should since my system is no slouch and while it isn't the latest and greatest, I would consider it to be in the top 20%,
it should be able to handle the conversion with no problem.
Are you aware of problems with the DNG software and or file format?
Is their any information I could forward to you to help solve the problem?

Photoshop Help | Digital Negative (DNG) - Adobe

DNG is a publicly available archival format for storing camera raw files. Adobe provides Adobe DNG Converter, a free utility that converts files from more than ...
That is off the net, therefore, Adobe looks at DNG as part of Adobe Photoshop, which it is if a person chooses to convert.
My issue has to do with it crashing, both my system and software.
I assume if people here are using it, then they can advise me if they are having similar problems.
I have also written Adobe directly several times over the last month and have yet to receive a response.
I apologize that I posted here, but since I consider DNG an integral part of Photoshop, then I think it is appropriate here.
I was also not aware of a DNG forum, if one exists.
Thank you for your assistance.

I'm having troubles converting my raw files from Nikon D5200 (NEF) to DNG. I tried using Lightroom 4, but it didn't identify the folder containing the files. So i downloaded the latest DNG converter but that too didn't identify the files kept in the folder location. So I downloaded DNG converter v7.3 for D5200. It identifies the folder and files; but it is giving me parsing error on trying to convert files. I'm running Windows Vista Home Edition SP1. Kindly advise. Thank you.

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.

D300 will not open as NEFS or DNG with CS2

hi,
using CS2 ( the only pshp activated on my MBP )
forgot to deactivate my home G5's.
purchased the D300
did not install its software NX or suite
did insert ACR 4.3.1 into adobe plug in
and also converted the NEF to dng
i still cannot open the files.
is it impossible to use CS2 with the D300? must i use CS3
or
what am i doing wrong?
must capture NX be installed
thanks

ACR 4.3.1 will NOT work with Photoshop CS2. The latest version that is available for Photoshop CS2 is ACR 3.7. There will not be any further updates. You need to to download and use the DNG converter, version 4.3.1. It will create DNG copies of your raw images that will open in Photoshop CS2 and ACR 3.7. Capture NX does not have to be installed to make this happen. You just need to use the most recent version of the DNG converter along with the correct version of ACR.

NEF to DNG 6.5 results in different number of unique colors, pixels and RGB values

I took pictures from my old Nikon D40. I converted them with the standard settings from NEF to DNG.
I then used UFRAW under Linux and saw that the pixel size increased from 3039x2040 in NEF to 3040x2040 in the DNG - and that the live view RGB values were about 5% higher for NEF that for DNG.
"FastStone Image Viewer" shows the same increase in pixel size. Additionally, it shows that the DNG has roughly 93,000 unique colors compare to 90,000 for the NEF file.
More pixel, different RGB values, different counted unique colors - what's going on here? This doesn't look like a 1:1 conversion?

Not exactly sure what you're comparing. For raw data you need to be comparing the original mosaic data values (not some converted result, or even partially converted result like demosaiced result). Are you sure that's what you're doing?

Can anyone tell me where I can aquire a Photoshop CS6 Raw converter(nef,not DNG) for my Nikon D600 Camera

Can anyone please tell me where I can aquire a Photoshop CS6 Raw Converter(nef, not dng) for my Nikon D600.
I would also be grateful if you could assist me in telling me how you install the "pluggin" into the suite software?
Any assistance would be most appreciated.

Lightroom 5.7 will not convert .nef to dng from my Nikon d750. Stand alone dng converter will not recognize or convert the files.

Lightroom 5.7 will not convert .nef to dng from my Nikon d750. Stand alone dng converter will not recognize or convert the files. Any know whats wrong?

I don't understand why you feel you need to use ViewNX to download your images from the camera. Lightroom has an excellent import process. I don't see that you gain anything by using the Nikon software. It seems to me that it has the capability of just creating more problems.
If you want to convert your D750 files to DNG using the standalone DNG converter thing you need to have DNG converter 8.7 installed. Once you have it installed, just choose the FOLDER in the DNG converter, but don't open it in the DNG converter file browser. If you open that folder then you will get the message that there are no files to convert. The converter works on the folder level, not the individual file level.

Strange artifact in some NEF and .dng files

Using a Nikon D80 with 4 GB Sandisk Extreme SDHC card; shooting full resolution NEF; Mac G5, Mac OS X 10.4.10, images are run through Adobe DNG Converter 4.1. Image is opened in Camera Raw 4.1 (and now 4.2) window within Photoshop CS3 Extended.
In some photos with dark areas, there is a single, tiny, transient on-screen artifact in form of a red dot, either two or three pixels square, which always appears in the same location against, say, a dark sky or trees. It can persist or literally disappear on its own after about two seconds. If the file is reopened in the same session, the red dot may not be there at all. If the loupe tool is used, it always disappears within the loupe after about two seconds, even though it may persist in the unmagnified screen. The good news is that opening the image as a .psd in Photoshop shows no sign of this anomaly, no matter how greatly magnified.
Note: It can also appear if I drag the NEF or .dng file over to Preview. But in this case, it does not disappear.
Does anyone have a clue what may be causing this?
A screen shot comparison from Camera Raw 4.1 is attached below. The left image shows the dot in place in the section of the photo and with the loupe.The right image shows the dot gone, but persistent in the unmagnified image.
Neil

Again, thanks, Thomas. Most, um, enlightening! <g> I've been shooting raw exclusively over the past six months or so. Camera Raw apparently did its job, which would explain why the pixel disappeared after a couple of seconds. I'll probably run the same image through Lightroom to see what happens. However, I can still see using .jpg once in awhile (family and friends snapshots destined for email or postcard-size prints). But then, the question begs, if other pixels are compensating for the bad pixels, does that materially affect overall resolution or appearance of the images? Although I've been aware of annoying "stuck" pixels on LCD monitors, I never really thought about how DSLRs deal with this. Neil

Any benefit to convert NEF to DNG

Does anyone convert their NEF (D300 in my case) files to Adobe DNG and then start their workflow?
Or are the NEF's just imported into Aperture and then adjustments are made?
I use Aperture now for a long time. I usually just import the NEF files. I've been using Photoshop CS4 to learn it and have just been sending the NEF file within Aperture to Photoshop. And of course it comes back to Aperture as a PSD file.
I ask because Aperture has a tendency to lag making adjustments. But I noticed Aperture doesn't lag if I make adjustments on the PSD file or a DNG file. Adjustments are in real time.
So I'm thinking of converting my NEF's as the first step of my work flow. Then import the DNG's into Aperture.
I have all of the NIK Software and working with this in Photoshop is 1000% easier in Photoshop than Aperture.
I can't seem to tell any degrading of the NEF converted to DNG. I've done a few now and compare. I can't seem to tell. Pre or post adjustments made in Aperture.
Thanks for any thoughts or opinions.

DNG is just Adobe's proprietary attempt to sell the world on using Adobe's RAW conversion format ("DNG," the result of converting camera makers' individual RAW files using Adobe Camera Raw, "ACR"). Adobe benefited greatly with PDF and wants to do the same with RAW DSLR capture.
DNG is not better. In fact most folks (at least the ones not already sleeping with Adobe) will most often find conversions by Aperture and/or individual camera vendors' converters (like NX2) to be visually better than ACR to DNG. However differences among converters are usually slight enough anyway to make RAW-conversion quality irrelevant when compared to workflow.
The conversion of RAW data is different for each individual camera, no RAW converter is best for all cameras, and the results of conversion are a matter of individual taste in any event.
Note that most camera vendors keep RAW algorithms and protocols very secret, so folks like Adobe and Apple do a lot of deduction (some say speculation) when building each camera's RAW converter based on imperfect information. That is why most folks consider Nikon's conversions of NEF files "best;" but unfortunately Nikon's workflow is atrocious.
...is there any significant advantage to converting (to DNG)?
No, there is significant disadvantage in converting NEF to DNG. You would be seriously disrupting Aperture's workflow just to achieve what most folks consider to be less-good RAW conversions.
Some photogs do find significant advantage in first using NX2 to convert Nikon NEF files to TIFF. Others find the differences from Aperture small enough not to justify the weight of the NX2 workflow.
I read the Adobe site regarding how DNG is more a standard then NEF or any proprietary camera file.
That is just disgusting Adobe marketing BS. Nikon was around supporting standards like their lens mount for decades before Adobe even existed. Even if Nikon self-destructed today there will always be plenty of RAW converters for the billions of NEF files already created.
Of course Adobe would love it if the world lowered their standards to some Adobe-defined lowest common denominator, but then we would probably not see the various consistently fast tech advances like the low light performance of the Nikon D3.

Unable to see converted NEF to DNG files in Photoshop CS

Aloha, my laptop recently crashed and I am in the midst of trying to restore my laptop to the way it was. I am using Photoshop CS and back in December 2009 I downloaded DNG converter. I am using a Nikon D90, shooting in RAW. I don't recall what I did after downloading the DNG converter but I was able to convert the NEF files to DNG by simpling clicking on the DNG icon, selecting the file and click convert and the NEF were converted to DNG files. I was able to use my Photoshop CS with these covverted files. In the restoration of my laptop, I loaded my Photoshop CS program and then did a search on-line for the DNG converter. I found a 5.6 version and later a 6.3 version. I first downloaded the 5.6 version. I then clicked on the icon, selected the files and click convert. I can see the NEF photos being converted. However, when I went into my Photoshop CS program, I did not see any DNG files even though I saw the files being converted. I downloaded the 6.3 version and got the same results. I also went into Change Preference and selected Camera Raw 2.4 and later. But I though I am seeing the files being converted to DNG, I do not see any of those converted photos in my Photoshop CS program. Can anyone help me? Am I missing a step or two? I would appreciate y'all expertise in this matter. Also, anyone knows how to uninstall one of these DNG converters I downloaded? Thank you very much, Ron

Aloha Jim,
I went on Google and typed in DNG 6.3 converter. The following appears:

I click on the proceed to download. The follow appears.

come on a window that says, Camera_Raw_6_3_updater.zip - WinRAR (evaluation
copy). In that window there are 4 folders. The first one does not have any
information except for 2 dots. The second folder is labeled META -INF. The
third folder says, payloads and the last is like a window, rectangular in
shape, white at the bottom 3/4 and the top portion is blue. It is labeled
AdobePatchInstaller.exe. Again, I am assuming I am suppose to click this. I
click it and then it looks like it is updating something, then a window that
says, Adobe Application Manger comes on which says, some updates failed to
install. Another messages says, update is not applicable. I don't recall
what I did next...tried other things but I finally got the icon (circular,
the top 1/3 white with 4 red letters, the bottom 2/3 greenish with a blue
arrow pointing down. It is labeled as DNGConverter_6_3. I clicked this
icon and get this open file - security warning window. It states, the
publisher could not be verified. Are you sure you want to run this
software. Name: DNGConverter_6_3.exe. Publisher: Unknown Publisher; Type

button I then get an error message saying, Installer integrity -check has
failed. Common causes include incomplete download and damaged media.
Contact the installer's author to obtain a new copy. More information at:
http://nsis.sf.net/NSIS_error.
I don't know what to do. Back in December of 2009, all I did was downloaded
the DNG file that I found on Google, click on the DNG icon, and my NEF were
converted so I could see it in my Photoshop CS.
Am I doing anything wrong. I would prefer not to invest $200 for Photoshop
CS5 since Photoshop CS along with DNG converter were meeting my needs. I
know it may take some time to write this but perhaps could you write down
the step by step process you would do from searching for the DNG converter,
selecting the converter, downloading the converter, activate it so
everything is set up for use with the Photoshop CS. I would appreciate it
very much. It has been very frustrating and time consuming in trying to
resolve this issue. I thought it would be so simple setting it up like the
first time when I first installed it.
Thanks again for responding to this matter. I appreciate it very much.

Nikon 5700 NEF and DNG

Does iPhoto '08 import DNG photos?
I've tried converting some Nikon 5700 NEFs converted to dng by either Lightroom or Adobe Converter, but get the unsupported format dialog. Odd that it attempts to import and then warns you, rather than telling you right away that it won't accept the files.

kenneth,
i think the problem is not all with aperture but in Mac OS X. try opening the nikon 5700 nef file with Preview and you'll see. my brother has a nikon 5700 and he had no problems opening nikon 5700 nef file on mac os x prior to 10.4.(?) running on a third-party upgraded powerbook (the wall street). he finally bought a new mac and this is when all his nikon 5700 nef files became incompatible. so something happened during the series of Mac OS X upates that broke the support for the nikon 5700 nef file.
i suggest that you also submit a feedback requesting support for the nikon 5700 nef file.
ps: they do listen, just be patient.

If I convert NEF into DNG the photo looks different

If I convert a NEF into a DNG, the DNG looks underexposed in comparison with the NEF. Why is this happening? I understood that it would be better to convert my photos into DNG because it is a universal RAW format but, it doesn't look anymore as I saw it on my camera.

Corina_PC wrote:
Why is this happening?
Because the preview (jpeg, embedded) in the DNG is a re-rendering based on Adobe defaults. It's not the same embedded preview that came in your NEF (which was created, initially anyway, in the camera).
To better understand, it helps to know how the story unfolds from the beginning:
When you press the shutter release, the camera takes the raw image data from the sensor, folds in the camera settings, crunches it through the Nikon image processing "engine", and compresses the result into a jpeg, which it subsequently stores (along with the raw data) in the raw NEF file, and shows you on the back of the camera, etc.
When you convert to DNG, Lightroom does something similar: it takes the raw image data from the raw file, ignores most of the camera settings (except, for example, white balance), crunches it through the Adobe image processing "engine", and compresses the result into a jpeg, which it subsequently stores in the raw DNG file, and shows you via OS codecs or in ACR, or Lr...
So, bottom line, you are just seeing the difference between current renderings of Nikon vs. Adobe. If you edit the NEF in NX2, the preview will be updated when you save the NEF. If you edit the DNG in ACR or Lr, you can also update the preview to reflect the current edits.
etc...
Hope this helps,
Rob.

Can't select NEFs with DNG

I'm running CS3 on a 2 GHz Intel Core Duo MacBook Pro that I've just upgraded to Snow Leopard 10.6.7. I'm trying to convert raw NEF files shot with a Nikon d7000. I understand that those files are not supported by CS3 Camera Raw (I have version 4.3.1) I have downloaded the DNG converter but am unable select the NEFs I want to convert. I have tried the various compatability settings in preferences but nothing is working. Any ideas? Thank-you.

I don't know if it would help, but there is a newer version of ACR for CS3 you could try. Go to the Adobe updates site, select Camera RAW Mac in the dropdown at the top and follow the links:

Do I need LR 5 in order to convert my Nikon D750 files from NEF to DNG files?

I currently have LR 4 and the new Nikon D750. I was using the Nikon View to convert my files from NEF to TIFF and get some editing done for clients previews. I know the Camera Raw 8.7 just came out on October 2nd and I am trying to download it but it will not install on my computer as I cannot find the short cut or the installed application when I go to all my applications on my computer. I open LR 4 and cannot see it in there either. What am I doing wrong? Do I need LR 5 in order to use the new Camera Raw 8.7? I have Windows 8 so it is not an unsupported computer version as was stated on your site where you can click the download for the Camera Raw 8.7.

Camera RAW is a Plugin that is used by PS CS, PS CC and PS Elements you cannot install it in Lightroom.
Each Lightroom update has an equivalent of Camera Raw built into the application, it does not use the Camera Raw Plugin.
LR 4 has the equivalent of Camera Raw version 7. e.g the latest version of LR 4.4.1 has the equivalent of Camera Raw 7.4.1.
The present LR 5.6 has the equivalent of Camera Raw 8.6 so when a new update for LR is released version 5.7 it will have the equivalent of Camera Raw 5.7.
However you can download the Adobe DNG Converter 8.7 RC and it can be used to convert your D750 files to DNG and import them into LR 4.
The converter is available at Adobe Labs.

.NEF to .DNG conversion - why the weight loss?

What info is tossed when converting from .Nef > .DNG?
For example, I just converted a file and the Info says:
.NEF (15.6MB) > .DNG (10.9)
Is that one third drop in MB just Nikon encoding? Or is the image affected?

Try posting in the DNG forum. There are separate forums for DNG and for ACR.
