RAW to DNG conversion.

Using PS CS5 and Nikon D200, Bridge and PS see the RAW files great. However, I just got a Nikon D7100 and PS does not recognize the RAW files. I downloaded the new DNG converter but my question is, do the RAW files have to be converted in the DNG program first, is it not a plugin for PS? I would think a plugin would work within PS, not have to be completed separately. Thanks.

Thanks for the responses Kelly and gener7. One video that I watched from Adobe said that the conversion could be accomplished as the files were being imported in Bridge and there is that option but it did not work for me. Everything works great when using the DNG converter program so it just adds another step. Thanks again.

Plain raw format - DNG conversion

Dear All,
Would you guide me regarding to converting plain raw format file to DNG file?
<definition>
1. plain raw format file
- the file is composed of Bayer pixel array. For example, 5M pixel raw file is composed of sequential 2592 x 1920 pixels, each pixel is represented by 2byte value. file size will be 2592*1920*2 bytes. The start pixel may be one of Gr or Gb or R or B
2. tuning information file
- the files below may be provided for enhanced DNG raw image processing
- start pixel information: Gr or Gb or R or B
- 4channel lens shading correction
- noise profiling
- white balance R/B channel gain
- color correction matrix
- gamma table
<what is conversion guide?>
1. Is there any available program or utility for converting this plain raw format file to DNG?
2. if not available, how can I achieve the conversion using available toolkit?
3. any other idea?
Thanks in advance.

I don't think that any program exists that will do that.
You can however use the DNG SDK to do what you want: http://www.adobe.com/support/downloads/dng/dng_sdk.html

Raw and DNG

Have been successfully using RAW and DNG conversion with Canon 20D in CS3. New Canon 5D Mark II. No longer able to covert to DNG or open RAW files. Have downloaded updates RAW 4.6 and corresponding DNG converter that are supposed to work in CS3. Still not able to open or convert. Any siggestions?

I can understand being angry when you find out your camera isn't supported by Adobe, as I remember I was, too, just not being angry enough to find JPG or DPP adequate instead of spending $200 on an upgrade. Adobe needs to pay their employees and not waste our money by hiring more people to keep all their old versions up-to-date, so once I got over being angry, I was ok with their policy. I suppose it's possible you'd need to upgrade your computer, again, to run CS4 or CS5, and that would be more than $200. My old computer will barely run CS4 and I don't have a 5D.2 so you're one step ahead of me.
Anyway, to summarize what the alternatives would be if you weren't avoiding them out of protest:
1) Upgrade Photoshop to a version that supports your camera, which would be CS4 or CS5 next spring. This would cost $200 unless you had to upgrade your computer again.
2) Manually copy your files from your CF card to your hard drive, then use the DNG Converter 5.5 to convert them to DNGs, then Bridge and ACR can work with them. This is free.
Another alternative I will mention, because this is what I do, is to use Lightroom, and then edit things in Photoshop if your processing requires it. Mine rarely does, anymore.
I used to shoot JPG and use Paintshop Pro to adjust my images and that worked until I found myself in a situation where I needed to correct white-balance more than worked well with JPGs, so I converted to shooting RAW, with a temporary phase of RAW+JPG because I wasn't sure.
Once I was doing RAW, it only took me a day or two to reject using DPP as very annoying. So I started using Bridge/ACR/Photoshop to process everything. At one point an independent company had a program call RAW Shooter, where they gave away the "lite" version for free, and it did a reasonable job. Of course Adobe bought them out, and then released a wonderful program called Lightroom based on the idea and some of the technology. Lightroom costs $300 for the initial version, $100 for major upgrades that mirror the Photoshop major upgrades, and has free minor updates for new cameras that correspond to the free interim ACR updates.
If Photoshop, itself, does what you want, and it's only ACR that you want to update whenever you get a new camera, then Lightroom is a cheaper alternative to updating Photoshop just to get a new ACR version.
As I said, I love Lightroom, and would hate to go back to use Bridge/ACR as my main processing model, again, let along use DPP or shoot JPGs.
The next version of Lightroom, LR3, which improves the detail rendering and color-noise-reduction (so far) is available for beta testing until April 2010, from http://labs.abobe.com/ It doesn't have luminance noise-reduction enabled because that is apparently still a work-in-progress after Adobe has fundamentally changed their RAW rendering algorithm and luminance NR is the quite difficult to accomplish, but Adobe wanted user-feedback on their new rendering and color NR without waiting to perfect the luminance NR.
I am enjoying using the beta although I have to go to Photoshop to use the Noise Ninja plug-in for higher ISO images.

Filter in adobe bridge to only select Raw files for DNG conversion

Here's my problem - I have a new DMC TZ70 camera and Lightroom 5.7 doesn't recognise the .RW2 files. I would need to buy LR6! Perhaps later.
So I thought I will import via bridge and convert to DNG.
So I open bridge and select the camera - fine - BUT there are files for the Raw images, the same number of JPEGs and some .bdm, .TDT etc files. (e.g. 3 raw + 7 others).
I can set up a filter to view only the Raw files when I see what files are there in the card folder in Bridge but when I select "get photos from camera" I can either select them all OR deselect and then I need to MANUALLY select the raw files. There doesn't seem to be a way of setting up a filter in the Downloader screen so that Bridge only selects the Raw files for conversion.
If I let it select all, Bridge converts the RW2 files to DNG but also brings in the jpgs and other files. I can delete these afterwards but this seems an inefficient way to do it.
Is there any way to manually select the raw files in the photo downloader screen?
Advice please, thanks, Mel

Not sure I follow completely, Mel, but Bridge allows you to View > Sort > Type... which would allow you, after sorting, to click on the first image with a specific extension, then hold down the Shift key to select the last in the series and handle them independent of the other files presented.

DNG conversions not opening

I dusted off an old Toshiba laptop that has a copy of CS4 Photoshop and the newest DNG Conversion software (v8.8). Pointed the DNG at a folder of RAW files (Olympus ORF), converted them, opened them in ACR and saved the files that are now .dng files in Bridge...but CS4 won't open them, says it doesn't support this file type. How can Adobe Photoshop not open an Adobe file type? I thought DNG made all RAW files backward compatible for Photoshop going back to the beginning of time. Any ideas, suggestions, solutions?

I got a couple of sample raws and converted them on the mac side using the 8.8 dng converter and they seem to open on both photoshop cs4 on mac and windows xp
Did you check to make sure both your photoshop cs4 versions have camera raw installed and are updated to camera raw 5.7?

DNG Conversion Fails in Camera Download

I've been using Photoshop CS4, Bridge and ACR for about a year. I was sold on the Adobe rationale for converting to DNG and have been doing so using the convenient check box on the Photodownloader screen. It has worked fine the entire time - until now. Suddenly that no longer works: although the DNG conversion box is checked Bridge only downloads the raw NEF files and reports at the end that it the DNG conversion failed on all of the photos that were downloaded.
So - here is what I've tried:
- Rebooted my Windows XP computer ( dual core - which has 4GB of RAM). Same results - no conversion
- Reinstalled Photoshop CS4 - and everything on the disk. Same results - no conversion
- Downloaded version 5.7 of Camera Raw (just found out there is a 5.9). However that seems to only update camera profiles - and doesn't change the version that displays on the Camera Raw preferences menu: 5.0.0.178. Same results - no conversion.
- Finally I downloaded the free DNG converter. It works, but I would much prefer to have the download program work
Any clues to solving this will be greatly appreciated.

That proves you did not install 5.7 correctly and you failed to remove the old 5.0 plug-in.

Significant reduction in file size from Camera Raw to DNG

Hi,
I am currently testing the conversion of Leaf camera raw files into DNGs for a photographer's archive. I am hoping to convert all of the mos files to DNGs because Leaf Capture and the Leaf Raw Converter are not being updated and because the photographer wants to have an Adobe centered workflow. In my testing I discovered that converting mos files to DNGs through ACR 8.4 and LightRoom 5.4 resulted in a reduction of file size by nearly 50%. A 44.5MB mos file became a 23.6MB DNG. From what I've read only about 15-20% of the camera raw file should be lost and all of the data lost should be propietary.
Here-in lies my quesiton, is there any way that I can track or determine exactly what sort of compression is being done to the mos file and what information is or is not travelling in the conversion to DNG?
These are the settings I have used for converting raw files to DNGs:
ACR:
JPEG Preview: Medium Size
Embed fast load data
Don't use lossy compression
Preserve pixel counts
Don't embed original
LIGHTROOM 5.4:
Only Convert Raw files
Delete originals after successful conversion
File Extension DNG
Compatibility Camera Raw 7.1 and later
Jpeg Preview Medium Size
Embed Fast Load Data
Thanks!

50%? - I thought we were talking about 15-20%?
In my first post I questioned why I was seeing a reduction in file size of 50% when according to forums and articles I've read I should only be seing a 15-20% reduction in file size. I then wondered what data I might be losing, which you addressed.
Same as what? - what were the results.
I was referring to testing I preformed on camera raw files produced during different years (all mos). I converted all files with the same ACR and LR settings and found that the DNGs always reflected a 50% reduction in file size. This test suggests that any conversion issues is not necessarily related to how the camera raw files might have been differently built across years.
Adobe's raw data compression is touted by DNG zealots, but I haven't scrutinized it enough to corroborate or refute.., but my experience is that reduction is relatively marginal. All of this assumes original is also compressed - if uncompressed in original source, savings would be large.
The files I am dealing with are definitely uncompressed which could account for the large reduction in file size. I didn't realize until I posted to this thread that converting to a DNG results in a compression of the original image data. I understand that this compression is supposed to be lossless like a lossless compression to a tiff and thus result in no decrease in image quality or harm to the original image. I am baffled by how it is possible that any compression of a file (especially by 50%) could not result in a loss of important data but I will accept that it is possible to have a truly lossless compression and that the size reduction I am seeing could be a result of all of the different processes a file undergoes that you have outlined.
I looked into the effects that backwards compatibility has on the conversion process which might interest you http://dpbestflow.org/DNG#backwards-compatibility
I also posted to luminous landscape's forums http://www.luminous-landscape.com/forum/index.php?topic=89101.new;topicseen#new
Although it wouldn't surprise me if the DNG conversion process tossed the xmp-like metadata, and kept the original stuff, but it would surprise me if it tossed the original stuff - but as I said before, I haven't scrutinized for completeness so I don't know.
I've done testing in which I converted .mos camera raw files with their sidecar xmps and without their sidecar xmps. My tests revealed that the DNG definitely carries over xmp metadata although it is not clear to me exactly how it is carried and if anything is lost.

DNG conversion fails sporadically with Get Photos From Camera

Camera: Canon 40D and 5D
XP SP2
CS3
Bridge 2.1.1.9
ACR 4.4.1
DNG Converter 4.3.1
Importing my files to Bridge using the Get Photos from Camera (GPFC) option results in sporadic DNG conversion failure. There's no pattern, just a lump of files that don't get converted at the end of the process. It's very frustrating because I have to manually go back and find the files that failed and use GPFC option again. Even then sometimes it fails again!
I'm attached to using the GPFC option instead of the standalone DNG converter because GPFC lets me automatically make a backup file to another disk and adds a template. But even when I use DNG Converter to import the files off my card, DNG fails for some of the files. Purging the cache only works half the time and for some of the files.
Is there any solution to the GPFC problem? I've seen people have similar problems, but with no real conclusions...
Any ideas? Thanks in advance.

Ramon,
No, I have tried purging/refreshing before and it doesn't help, because the un-converted CR2 files are just skipped over and put in the same destination folder as the successfully converted CR2 files (to DNG). I thought it might be a memory issue, but I never have any other applications open. As a test, I purposely opened some other applications to see if MORE CR2 files would be skipped, but the amount of files skipped was still random.
My "DNG Conversion Settings," accessed through the Get Photos From Camera dialogue, is set to:
Jpeg Preview: Medium Size
Compressed (Checked)
Preserve Raw Image (Checked)
Embed Original Raw File (UN CHECKED)
Could some of my Edit>Preferences>Cache options be overloading things and causing skips? I use the default settings because I wasn't confident with messing around with the cache.
Thanks

DNG conversion fail and Photoshop will not open my NEF files (Newbie question)

Two part question. First, I just recently installed photoshop CS4 to my (windows vista) computer and I go to upload NEF photos to bridge and I check the box that says "Convert to DNG" and when it finishs uploading it says "Files successfully copied, However, DNG conversion failed." It says it everytime and I don't know what to do about that.
Second part: I try to open my NEF files in photoshop it says "Could not complete your request because it is not the right type of document." I am using a Nikon D90 and I don't know if that has anything to do with this. I apologize if this question is in the wrong forum, I am new to this and I thought maybe camera raw had something to do with this at least.
Thanks for any help

You need to update your Camera Raw plug-in to either version 5.2 or 5.3RC, as well as the new DNG converter. They are available on the Adobe download page, and there are complete instructions for installation available there.

Camera Raw and DNG Converter for PSE10 and PS CS5.5

I recently bought a Nikon D5200. I have Photoshop CS5.5 at home and PS Elements 10 at work. I had to download a DNG coverter in order to open my RAW files (NEF). I have 2 questions: 1) Which are the latest updates that will work with each of these programs (the listings on the Adobe Download pages are confusing) and 2) Do any of these updates allow a new NEF file to be opened directly without the extra step of DNG conversion? Bit of a pain.

Latest DNG converter can be downloaded from following link:

How can one convert a PSD file into a RAW or DNG file?

Lightroom does not assemble panoramas. One must use an external editor,eg, Photoshop Elements, to construct a panorama. Lightroom prepares the selected images by converting them to PSD files before sending them to the Elements Editor. When the panorama is achieved, it cannot be saved as a RAW nor DNG file even if either of those formats were the original data format type in Lightroom. Thus when the panorama is imported back into Lightroom it is brought back as the PSD or something of your choosing; but you cannot choose a RAW nor DNG format. The result is a folder in Lightroom with a hodge-podge of formats.
Question: How can the PSD file panorama be converted into a RAW or DNG file in this transfer from an outside editor to Lightroom?

That simply cannot be done. The conversion has to take place in order for Photoshop to create the panorama. Photoshop, by itself, without Camera Raw, cannot edit raw image data. By the time an image is opened in Photoshop is no longer raw image data. Photoshop is not capable of saving raw image data. The best thing to do is perform is much of the work as possible using using Lightroom. When I do a panorama image, I highlight all of the images and use the menu option to match total exposures. Then I do as much as possible on those images in Lightroom. Once the images leave Lightroom the raw editing is finished. Anything from that point onward that is done in Photoshop must be saved to a different file format.

Embed Original Option for DNG Conversion

I have switched over my digital workflow now to DNG. I would love to see Adobe add an option to embed the original RAW file to it's DNG conversion in Lightroom. I was hoping that someone from Adobe would read this and take this suggestion into consideration...if not in v1.1, maybe in a future version. Thank You!

Ok, I am a novice here, but I am wondering:
What is the advantage to embed the original RAW into a DNG?
I believe I understand the value of the DNG: that it provides a single format for RAW data that simplifies the job software needs to do to render the RAW data, rather than needing to translate a zillion file formats. Also it removes the need for sidecar XMP files. OK, that sounds like good things.
So, assuming one already has a good backup of the RAW stowed away somewhere, and also assuming that the RAW-to-DNG converter is competant to do what it is supposed to, Why would one want the RAW embedded in the DNG?
One other question: would embedding the RAW file double the size of the DNG?
Thanks

"There was not enough memory" error, DNG conversion.

I have CS4 and I like to convert my files to dng, however, I can't seem to do it on multiple raw files, because after fifty or so, I get the message, Incomplete because 'There was not enough memory.'
I originally thought this may have had something to do with Bridge and trying to save way too many files through acr in bridge, since bridge is a bit of a ram hog at times and has cache issues, so I tried using the Adobe DNG Converter standalone application, and the same thing happened.
I am trying to convert just over a thousand images, NEF, about 15M each. I have several hundred gigs of HD space, GeForce 8600GT video, 2G ram, WinXP SP2.
I track my actual memory usage and adobe dng converter has never used more than 6MB of memory.
Anyone know why I can't convert my files?

I want to try to reproduce this problem, a few questions...
Which version of the DNG converter did you use (the latest is 5.5)?
What camera produced the NEFs?
What NEF settings did you use, if any, compressed, uncompressed, 14-bit, etc.?
What DNG conversion settings did you use?
Did the NEFs already have settings (XMP sidecar files?). If you did have settings, what kind of settings, just basic adjustments, or did the settings also include localized corrections, spot heals, etc.?
Thanks,
David

Sporadic failure dng conversion

I've recently upgraded from Windows XP (SP3) to Windows 7 Ultimate 64 bit. At the same time I upgraded from 2 gb of RAM to 4 gb. Since the upgrade I've been experiencing random errors in DNG conversion. I usually convert to DNG inside Lightroom 2.5 by selecting the files to be converted and then use the command Library...convert to DNG. This process randomly freezes/hangs. I've tried using the standalone DNG converter from Adobe (5.5), but this results in random errors of DNG conversion (about 10 % of files fail conversion). The RAW files I'm trying to convert are from a canon eos 350 d. I've never had an issue using Windows XP. I've tested the RAM with Windows Memory Diagnostic - no errors are reported. I'm not experiencing other issues.
I would appreciate feedback. Has anybody experienced similar issues? Any ideas as to what could be causing the problem?

I solved my problem - it was caused by a conflict between Lightroom 2 and the virus software Eset Nod32. After uinstalling the latter, I have not experienced issues with DNG conversion.

DNG Conversion - preview size

In lightroom when converting files to DNG on the pop-up screen is the Choice: Size of the Preview file: Large, Medium or Do not create.
1. what is the file size for large and medium?
2. What is the impact of NOT creating a preview? When I've tested NOT creating a file I can still open the file in my lightroom grid and loupe view. I can also view it in Windows vista Preview when right clicking on the image file on my hard drive.
3. Where do these "Previews" come into play?
4. Also, I have noticed that if I convert a JPEG file to DNG the file size is about 4x larger. Should I reserve DNG for only my raw files such as my .mrw and .cr2? Has anyone else observed an increase in file size after DNG conversion?
5. What is the deal with DNG anyway? I havn't seen the big manufactures like Canon with the new EOS-1D Mark IV and Nikon's new D3s,include the DNG as a file format selection on their cameras. What do they know that I don't, about DNG?

1. what is the file size for large and medium?
Medium is screen sized, the other option is full sized, not large.
2. What is the impact of NOT creating a preview? When I've tested NOT creating a file I can still open the file in my lightroom grid and loupe view. I can also view it in Windows vista Preview when right clicking on the image file on my hard drive.
Lightroom generates it's own preview. It's just handy for portability, so how the file looks is available to programs that can't understand the internal settings.
3. Where do these "Previews" come into play?
Lightroom will use them in Library intially. Like I said above, it's handy for other programs for managing and printing with the Lightroom settings, especially with a full sized preview.
4. Also, I have noticed that if I convert a JPEG file to DNG the file size is about 4x larger. Should I reserve DNG for only my raw files such as my .mrw and .cr2? Has anyone else observed an increase in file size after DNG conversion?
You should. The JPEG doesn't get converted to a Raw, it's just convenient to have all DNG. The increase happens because Lightroom removes the JPG compression AFAIK.
5. What is the deal with DNG anyway? I havn't seen the big manufactures like Canon with the new EOS-1D Mark IV and Nikon's new D3s,include the DNG as a file format selection on their cameras. What do they know that I don't, about DNG?
Nikon and Canon have proprietary information in their Raw files. Yes it's rather a pain when they release a new camera. Sticking to a DNG format would really help with this, if they came on board. DNG is just a way of providing a common Raw format.

RAW to DNG conversion.
