Oops!
I misunderstood. You want to open a DNG or NEF, not convert to DNG, and you want to do it free.
Then I better not mention the usual suspects, Lightroom, Photoshop Elements, & Photoshop CS5.

Perhaps you should mention ViewNX for opening NEF for free.

Your question is like a guy in the desert with an electric car. you ask "where do I plug in?". anyone who uses weird photogaphy formats is asking for trouble. stick with common ones…JPG or RAW

Weird? The format for all Nikon cameras that shoot RAW is a .NEF file that can be converted to a .DNG file.

Both FastStone Image Viewer and IrfanView open, view and allow some basic editing of .DNG files. I assume they will do the same for .NEF files, but I convert my .NEFs to .DNGs when they are downloaded.

Both FastStone and IrfanView are free programs.

DNG is not a weird format. Photoshop will open them, so with Bridge, and Macintosh views them natively through the Finder and Preview. If you wish to know, DNG is an extension of the TIFF structure and is open source.

Leica chose DNG format. It’s very good.

Actually, RAW is not a file format. Each manufacturer has its own format for RAW data, and Nikon’s happens to be NEF. Nothing weird about that. DNG is a universal format for RAW data, by Adobe. Again, nothing weird about that.

Well, maybe he got one in DNG format. I have had some strange files (from various places) and usually put in "free converter" and what I want to do (in Google) and find something.

So why don’t DNG files open in Photoshop? (I think it said they would in CS5) I don’t think I’ve ever had a DNG file. My Canon camera shoots in RAW that just opens in Photoshop.

DNG files are opened in Photoshop via ACR.

DNG or Digital Negative is an openRAW image format. It is based on the TIFF/EP standard format. This is Adobe’s attempt to create a universal RAW format.

DNG is a RAW data container which uses raw image data from an image sensor, and is structured as a TIFF plus metadata. It is used as the RAW data wrapper by several camera manufacturers such as Leica. In order to have DNG used as a "digital negative" for archiving purposes and avoid the ever changing generations of RAW by manufacturers such as Nikon and Canon, Adobe has provided the DNG converter, which is a compact version of the current ACR and a UI used solely for reading proprietary RAW wrappers such as NEF, CR2, RAF, etc. and then converting them to DNG and saving them complete with intact metadata.

Original DNG’s and DNG’s created using Adobe’s DNG Converter are standard RAW sensor data wrappers and can only have that data read using RAW file processing software such as ACR.

Once opened in any photo editing software such as Photoshop, Lightroom, Aperture, iPhoto, Preview, etc.
it is treated just the same as any RAW format and cannot be saved as as an adjusted RAW file, only one of the 16-bit or 8-bit image file formats such as TIFF, PSD, TGA, JPEG, PNG, etc.

You have to be careful. You cannot access the DNG directly from the link John provided. If it opened in your browser you are only seeing the imbedded jpeg.
To access the actual DNG got the the Ken Rockwell article and scroll down until you get to the image titled "Fern Springs, Yosemite Valley". Below the title you will see "Full-resolution © JPG(9.5MB)" from "kamera-original © DNG(18MB)". Do not open the "kamera-original © DNG(18MB)". Right click on it and download the linked file. That way you will have the full 18MB DNG file.

That file can be opened in ACR and processed as a RAW file.

you are a super pro in photography and know your stuff
I am not. i am a little guy who takes his canon eos camera out for the day and shoots nature, family, travel, etc, etc My biggest concern is the composure of the pic. if the pic is worthwhile, i will then take several pics of that object, and judge when back home then i load my JPG pics into photoshop. then crop, enhance, and save the file
I do not want to spend the time with all this conversion crap most amateurs don’t. photography and photoshop is my hobby I hope you see my point
P.S. thought about starting a new newsgroup.
calling it alt.graphics.photoshop.amateur
it would enable us idiots to to share stories and problems, and include photography. but the group would be informal like a sit-down group and gab, swap stories
what is your opinion ?? Carrie (and others) are you listening thanks for input on files

Sure, point well made. I understand. Note that opening a RAW file in Photoshop is automatic. Just clicks on the first dialog, and the file opens for you in photoshop. If you have Bridge it’s more fun.

You’re an idiot.

out for the day and shoots nature, family, travel, etc, etc My biggest concern is the composure of the pic. if the pic is worthwhile, i will then take several pics of that object, and judge when back home then i load my JPG pics into photoshop. then crop, enhance, and save the file
I do not want to spend the time with all this conversion crap most amateurs don’t. photography and photoshop is my hobby

You really need to stop pretending you speak for anyone other than yourself.

I hope you see my point

Your point is, you’re an idiot.

P.S. thought about starting a new newsgroup.
calling it alt.graphics.photoshop.amateur

You can’t even type a complete sentence. What makes you think you could get a new newsgroup off the ground?

it would enable us idiots to to share stories and problems, and include photography. but the group would be informal like a sit-down group and gab, swap stories
what is your opinion ?? Carrie (and others) are you listening thanks for input on files

Please do fuck off, and take the prattling twat with you.

Yes, I see your point and I agree with it.

However, a little extra knowledge about your hobby can go a long, long way.

When I see statements like you originally wrote "anyone who uses weird photogaphy formats is asking for trouble. stick with common ones…JPG or RAW" makes me think you are using your excellent camera just like a disposable drug store camera.

So why don’t DNG files open in Photoshop? (I think it said they would in

As you learned, they do open in Photoshop which calls ACR. You need to try it. You might have some DNG files in your Photoshop distribution media. Or download this sample:
http://www.kenrockwell.com/trips/2009-10/images/L1004220.DNG

Okay, trying it! I like to learn something new all I can, and actual doing
it helps.
It opened, nice picture!

You have to be careful. You cannot access the DNG directly from the link John provided. If it opened in your browser you are only seeing the imbedded jpeg.
To access the actual DNG got the the Ken Rockwell article and scroll down until you get to the image titled "Fern Springs, Yosemite Valley". Below the title you will see "Full-resolution © JPG(9.5MB)" from "kamera-original © DNG(18MB)". Do not open the "kamera-original © DNG(18MB)". Right click on it and download the linked file. That way you will have the full 18MB DNG file.

That file can be opened in ACR and processed as a RAW file.

Regards,

Savageduck

I clicked on it and it (the link) and opened in the PS (CS3) RAW option. Isn’t this what it’s supposed to do? I played around with the settings for a bit, to change it.

Just to clarify, if you open a RAW file, in this case a DNG in CS3, what you call "RAW option" should be "Adobe Camera RAW" (ACR).

Once you have made adjustments in ACR you should be able to open into CS3 with several options: opening the file, opening an adjusted copy of the file, or open the file as a "Smart Object". You can also choose the color workspace & 8-bit or 16-bit mode at this time. You can then edit and apply any corrections you choose to in CS3. You can then save the result as a TIFF or PSD If you are in 16-bit mode. To save as a JPEG or PNG you will have to make sure you are working in 8-bit mode.

I am not a "Pro" but I take the trouble to learn about what I use, and I use Photoshop CS5. I have been using various editions of Photoshop since PS7.

….and there is nothing wrong with that methodology, except I am sure you biggest concern is probably COMPOSITION rather than "composure", unless you are more concerned with the mental state of your images. 😉

I do not want to spend the time with all this conversion crap most amateurs don’t.

That is your opinion and you shouldn’t associate "most amateurs" with your opinion.

photography and photoshop is my hobby
I hope you see my point
P.S.

Just because photography is a hobby for you is no rational for avoiding the potential of digital photography and the software you use. Photography is my hobby, and has been for some 50 years. Just because it is a hobby I don’t deny myself a quest for excellence and knowledge within that hobby. I choose to know how each of the tools I have work. I also choose to extract the best I can from my equipment, and in the case of my DSLR I choose to shoot RAW 99% of the time. Sometimes hobbyists can be quite knowledgeable on a subject.

thought about starting a new newsgroup.

That is not necessary. There are plenty of photography groups catering to all levels of ability. Most of those who lurk or contribute to this group are "amateurs". Some of us who might have an answer try to answer it without being in anyway judgmental, I know I try to do that. Sometimes others might have a different way to reach the same result (usually in Photoshop there is more than one way to solve a problem).

If you want to "gab & swap stories" then take that conversation to Facebook or G+.

Sure, point well made. I understand. Note that opening a RAW file in Photoshop is automatic. Just clicks on the first dialog, and the file opens for you in photoshop. If you have Bridge it’s more fun.

If they are using any recent edition of CS(x) they will have Bridge, using it is a different issue.
Personally I use CS5 with its associated version of Bridge. Opening any RAW file in the Photoshop dialog whether directly in PS or in Bridge, the RAW file will ALWAYS open in the intermediate conversion software, Adobe Camera RAW (ACR).

Remember, the RAW files are not directly editable. If you make changes to the RAW file (or DNG for that matter) in ACR, you can go back into Bridge and apply those adjustments to a batch of files, the single file. Those adjustments are not made to the RAW file, but are added as a "Sidecar" XMP file, that preserves your original "Digital negative". This is how nondestructive adjustments to DNG files are made in Lightroom.

From everything I know of DNG edits made to the DNG, of NEF or any other RAW file are only recorded as XMP "sidecar" files. The actual DNG is not altered.

In order to edit a DNG in Photoshop "RAW conversion" has to take place first, for Adobe this is done with ACR which reads and processes the RAW sensor data, and the EXIF and other metadata from the camera. After ACR adjustments are made and you click on the "Open Image" button, the ACR adjusted file will be converted to an editable output format, usually TIFF. Until you save the work being done on this image the file will still show as ABCxxxx.DNG on top of the PS workspace window.

So this DNG shown in ACR is set to open in CS5;
< http://homepage.mac.com/lco/filechute/ACR-SC-01.jpg >

Once open in CS5 with the "Save" dialog open, the various and only available file format options are shown;
< http://homepage.mac.com/lco/filechute/CS5-02.jpg >

If you leave this working file in 16-bit mode and retain the qualities and data of the original RAW file you can only save in the following file formats:
Photoshop – PSD
TIFF (16-bit) – TIF
Photoshop Raw – PRAW

The first two (PSD & TIF) are your only real options, since the "Photoshop Raw" PRAW option is misleading. If you read the disclaimer in that save dialog you will find the following warning; "The Photoshop Raw File format does not fully encode the image mode and size, among other things. The image may not be fully restored when you reopen the file."

….and here is that dialog window with the alert notice. < http://homepage.mac.com/lco/filechute/CS5-03.jpg >

So you are not rebuilding and overwriting a DNG file or RAW data.

So to answer your question; No, saving an adjusted DNG or any other RAW file, or to reverse engineer and/or overwrite the original DNG is not possible.

The other format options for saving are as follows and each have their various characteristics and limitations, none of them retain the full information found in RAW data, or the adjustment data which can be saved in a PSD or 18-bit TIFF.

Large Document Format – psb
Cineon – cin
IFF Format – iff
JPEG – jpg
JPEG 2000 – jpf
Photoshop PDF – pdf
PNG – png
Portable Bit Map – pbm

Well, it is, kinda. A whole bunch of adjustments can be made to the DNG file. Close that file, and re-open it later, and the adjustments you made are still in place. But – and here’s where the "kinda" comes in – you can change all those adjustments back to where they were before you did anything or to any other settings.

No, it’s not usually a TIF. The format must be designated. You can designate it to be a jpg, a TIF, a PSD, or one of several other formats. It will save as a jpg if there is only the single layer, and save as a PSD if there are multiple layers. I can’t remember saving as a TIF. All my files are DNGs, jpgs, or PSDs.

So to answer your question; No, saving an adjusted DNG or any other RAW file, or to reverse engineer and/or overwrite the original DNG is not possible.
? The adjusted DNG will re-open with the same adjustments made.

Yes and No. Yes, the actual RAW data inside the DNG is not altered. No, the DNG does not require a sidecar file, the edits are stored as metadata inside the DNG file. Therefore, all edits made to a DNG file using ACR can be reversed.

….and that is the point, the RAW files remain unaltered regardless of what you might do to them in ACR or Lightroom. This is the key to non-destructive editing in LR and ACR. Only the XMP is changed (that is in effect an instruction set recording the adjustments).
In order to edit a DNG in Photoshop "RAW conversion" has to take place first, for Adobe this is done with ACR which reads and processes the RAW sensor data, and the EXIF and other metadata from the camera.

Agreed, I never save as TIF, and I also use DNG, PSD, and JPEG. However even though you might not see it, TIF is what you are going to be working with when any RAW or DNG file is converted in ACR to open in CSx.
The "save" dialog is where you make your decision on format. If your work flow is in 16-bit you will only be able to save TIF or PSD. JPEG’s can only be saved as copies or must be converted to 8-Bit before saving.

Usually when a DNG file is converted editing in ACR and then converted to open in CSx, or if you make the initial adjustments to the DNG in LR and export to CSx for other editing the final saved file will either be saved as a PSD or a TIF if you are going to maintain the 16-bit mode.

Both DNG and PSD are subsets of TIF and for the conversion to an editable format Adobe will take the road of least resistance and default to TIF.

I know you use Lightroom quite a lot. Try this, in the LR "develop" module select a DNG and select "Edit in Photoshop CSx" by right clicking on the thumbnail and making the selection from the dropdown menu. The DNG will open in CSx perform whatever Photoshop edits you need to and then just "Save" the file. It will be re-imported as either a TIF or PSD depending on your particular setup. The advantage to using PSD is being able to save un-merged layers. The saved file should now show in LR with a name which looks something like this DSC1234-Edit.tif or DSC1234-Edit.psd.

So to answer your question; No, saving an adjusted DNG or any other RAW file, or to reverse engineer and/or overwrite the original DNG is not possible.
? The adjusted DNG will re-open with the same adjustments made.

What you are saying is true for edits made to DNG files in Lightroom, or recorded to NEF or DNG in ACR – and not opened in CSx by clicking on the ACR "Done" button. The DNG will always remain unaltered, the adjustments are recorded in the "sidecar" XMP files. I am usually able to find the associated XMP along side the DNG file. One of my folders can look something like this:
< http://homepage.mac.com/lco/filechute/screenshot_07.jpg >

When you reopen the DNG or other RAW file the adjustments made in ACR or Light room will reopen with the adjustments recorded in the XMP file. The DNG, or other RAW file remains unmolested and pristine.

No, DNG does not have sidecar files. That is what makes DNG different from other RAW formats. The adjustments are stored in the EXIF data inside the DNG file itself.

A good book is a very subjective topic. My suggestion would be to use Google. If you Google "raw vs dng" you will come up with about a gazillion hits. You could also try "acr tutorials" for another boatload of hits.

I personally use Lightroom which is nothing but an organizer/librarian program packaged with the ACR engine for image editing. Martin Evening has a superior book for this environment which explains RAW, DNG, and parametric image editing in the Lightroom environment.

If you shoot with a EOS DSLR you should really consider
shooting in raw. The conversion to JPG throws away a lot of data that can be very useful.

then crop, enhance, and save the file

Your question is like a guy in the desert with an electric car. you ask "where do I plug in?". anyone who uses weird photogaphy formats is asking for trouble. stick with common ones…JPG or RAW

Actually, RAW is not a file format. Each manufacturer has its own format for RAW data, and Nikon’s happens to be NEF. Nothing weird about that. DNG is a universal format for RAW data, by Adobe. Again, nothing weird about that.

So why don’t DNG files open in Photoshop? (I think it said they would in CS5) I don’t think I’ve ever had a DNG file. My Canon camera shoots in RAW that just opens in Photoshop.

Because Photoshop itself doesn’t directly support any RAW format. And during the RAW wars between all manufactures Adobe releases its own RAW format hoping it will become the Univeral RAW format.

And others still have to release newer RAW format for each newer model, and it seems like they can’t use Adobe’s DNG because it may not be free to them. Or the RAW formats is still changing now and then not in final stage yet.

Photoshop itself has to use ACR or LightRoom to open RAW formats (inclusing DNG I think as I haven’t tried DNG myself) as they are RAW Converters

Just asking you, Savageduck, but are you aware of the DNG that can save the changes you make on it, thus the possibly of reverting the original?

*If* (I know it is) DNG is one of the many RAW formats then the change(s) won’t be saved to DNG file, but it will save to the additional file which contains all the change.

Example, if the RAW file is "John J Stafford.DNG" then there will be another file like (example) "John J Stafford.XXX" which contains all the newer information.

*If* you DELETE or RENAME the "XXX" file then the DNG will return to its very original stage.

And this is one of the reason why Photoshop itself should be able to open and retouch DNG and other RAW formats but it won’t. Because it can’t store all other changes (like Liquify, Style, Mask, Brush, Dodge/Burn, Magic Wand etc.), it just not worth the trouble.

Just asking you, Savageduck, but are you aware of the DNG that can save the changes you make on it, thus the possibly of reverting the original?

*If* (I know it is) DNG is one of the many RAW formats then the change(s) won’t be saved to DNG file, but it will save to the additional file which contains all the change.

Example, if the RAW file is "John J Stafford.DNG" then there will be another file like (example) "John J Stafford.XXX" which contains all the newer information.

*If* you DELETE or RENAME the "XXX" file then the DNG will return to its very original stage.

And this is one of the reason why Photoshop itself should be able to open and retouch DNG and other RAW formats but it won’t. Because it can’t store all other changes (like Liquify, Style, Mask, Brush, Dodge/Burn, Magic Wand etc.), it just not worth the trouble.

Thank you, Joel. I will now definitely learn-up now.

From everything I know of DNG edits made to the DNG, of NEF or any other RAW file are only recorded as XMP "sidecar" files. The actual DNG is not altered.

Yes and No. Yes, the actual RAW data inside the DNG is not altered. No, the DNG does not require a sidecar file, the edits are stored as metadata inside the DNG file. Therefore, all edits made to a DNG file using ACR can be reversed.

I’m getting confused. Can you recommend a good book or other doc that might help me master this subject?

You just need to make thing more simplier then you should understand.

– The RAW format will always remain 100% original. Nothing will touch itself

– All the changes will be stored in an additional file (see other message). I don’t remember the exact filename, but lets make the "XMP" file from Savageduck is the correct filename then he is right.

Now lets look at the whole thing this way. You know EXE or COM is the *executable* extension for DOS and Windows, and Windows has DLL (Dynamic Link Library) is an additional file for COM/EXE. DLL can’t be operated all by itself, but with COM/EXE it can communicate with the OS just like COM and EXE do.

– And I would say you don’t need to spent money on book *unless* you want to write a book about RAW format yourself. I don’t read book about RAW, I don’t read lot of information about RAW except when it first instroduced many moons ago, and I read so many misleading info.

So, I just mess with the RAW and the additional file created on the RAW file(s) I adjusted to come up with the good book myself. Here you can try

1. Copy dozen of RAW file to a specific folder

2. Messing around with one or few, then look at the folder again to see how many additional file is created besides the original RAW

3. Studying the adjusted RAW (make it so wild so you won’t mistake)

4. Delete the additional file (XMP for example), then look at the *wild* RAW again, and it should return to the very original stage.

Then you should be able to figure out what the XMP doing in the folder besides eating up more disk space.

No, that is not correct. DNG is an exception to this rule. In case of DNG the changes ARE saved the DNG file, but not as edits of pixels. They are saved as instructions in the EXIF data. The RAW data remain untouched, as is the case with any other RAW file. With other RAW files the edit instructions are indeed saved in a so-called ‘sidecar file’, but in case of DNG the sidecar is merged into the EXIF data.
