Metadata baked-in after Convert Photo to DNG?

Since I did Convert Photo to DNG to all my photos (originals were .CR2 and were Developed as well) it seems that Lightroom baked the previous metadata (XMP) to the new .DNG files so now, when I hit the " \ " keystroke to see " Before " (under Develop module) Lightroom now thinks that " Before " is the current state...
This is really bothering me, is it normal that there is no more " Before " state just because I converted all my photos to .DNG
Also, Lightroom history is now showing me " From Matadata " as the last action in the History list... Althought I never used the " Read Metadata from File " function...
So basically, I just converted to DNG all my photos and would like to be able to use the Before function " \ " under the develop module as I use to do with the .CR2...
any help would be appreciated!
thanks!
Danny

I processed a Nikon .nef raw file in Lightroom
. Then I went to the Library Module under
Library and chose Convert to DNG. After the conversion
the complete history was still available. However, the Before/After function using \ or Before/After Views did not work. It was necessary to click on the History State to compare views. Using the Before/After Views, the original could be compared to the processed view by clicking on the Import state.
This will not be a problem if the files are converted to DNG during initial import.
I also recommend backing up originals and all processed files along with the Lightroom database on a least two drives on location and another off-site.

BUG Before/After Function stopped working after Convert Photo to DNG

Hi,
I just converted all my photos to DNG using Lightroom's Convert Photo to DNG function and the Before/After " \ " function (in Develop module) is not working anymore... same problem in Lightroom 3.0

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.

Convert Photo(s) To DNG not permitting multiple conversions

I'm having a problem where, for extended periods, I can only individually convert photos to DNG.
Even when I have all images in a folder selected, the menu dialog reads "Convert photo to DNG...".
Currently, I'm experiencing this with Lightroom 2.3, but the problem has intermittently been an issue back to Lightroom 1. I'm using an Apple MacBook Pro, currently v10.5.6, with 4GB of RAM and ~ 10 GB of free disk space (admittedly not much, but the sooner I can get files converted to DNG, the sooner they're archived off of my hard drive).
Any one else having this problem? Any ideas what to do about it?
The image at the following link is a partial screenshot: http://lunasa.net/samples/Convertphoto.png

You need to be in Grid view before will operate on multiple selected images. The screenshot shows that you're in loupe view.

Loader/DNG Converter won't close after loading photos into Bridge

This is a very recent problem. Previously, after loading photos the loader would close, Bridge would open at the folder I created through the loader and that was it. Now after all shot are loaded, Bridge opens at the last folder I had open previously and the loader remains open. Clicking on the X box won't close it. I have to go into Task Manager to do this. I tried a full re-install to no avail. I've looked at preferences and don't see anything that helps.
I haven't done anything other than what I noted above. I tried re-installing PhotoShop and Bridge and that didn't fix the problem. The only other thing that has happened since I noticed this problem was that Windows updates automatically installed. I'm on Windows XP Pro SP3. The problem is not a show stopper but it is annoying.
Anybody have any ideas why this would happen and how to fix it?

OK, I tried changing the Preference by opening Bridge with the Ctrl key held down but I wasn't presented with the popup noted.
However -- D'OH! -- last night when I inserted my card into the reader and the dialog came up asking what I wanted to use to open I noticed that it was defaulting to Bridge CS3 (I still have some CS3 software on my machine). So I scrolled down, found Bridge CS4 and all is just fine. Thanks for the helps and tips. I do appreciate it. And I hope you can forgive my brain fart.

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.

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.

Still color in photos after converting to B&W

Hi there,
I have a very strange problem. After converting pictures to black and white in Lightroom (doesn't matter if I choose B&W in the basic menu, set the saturation to 0, set the HSL saturation sliders to 0 or choose a B&W preset) my pictures still have some colors in them. Before and after exporting.
The pictures are shot in RAW with either a 550D or a RX100. Same results for all. I use Lightroom 4.3.
I searched a lot on google and also here in the forum and didn't find anything about it.
Any ideas?
Regards,
Julian

If you have Lr and PS side by side they will display identically. If they're not something's definitely wrong, and I agree with ssprengel that it is most likely a bad monitor profile that one of them chokes on.
If you don't calibrate and profile the monitor yourself (which is the right way to do it), the safest bet is always to use sRGB (or if you have a wide gamut monitor Adobe RGB, but you don't). >This thread< contains a description of how you do it.
Some background:
Monitor profiles contain two parts. One, simply put, fixes white point, corrects the response curve and removes color casts. This is loaded into the video card (or the monitor itself) and affects everything system-wide. This is the calibration part.
The second part is the profile itself, which is more complex. It is, in short, a complete description of how the monitor behaves in three-dimensional color space. Among other things it defines exactly the position of the three primaries. It takes the calibration into the picture, so in other words it is a description of the monitor in its calibrated state. But only color managed applications read the monitor profile and correct for display accordingly. Other applications will just ignore it and send the numbers straight through.
This second part, the profile itself, is what frequently causes problems, because many profiles aren't written correctly. Monitor (and laptop) makers are notorious for this. You'd think they'd get it right, but they just don't.
To make matters worse, these bad profiles are often pushed through Windows Update, so people don't even know they're being installed.

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:
Product Adobe Camera Raw and DNG Converter Version 6.3 Platform Windows File
Name DNGConverter_6_3.exe File Size 50.6MB
Proceed to Download<http://www.adobe.com/support/downloads/thankyou.jsp?ftpID=4924&fileID=4585>
I click on the proceed to download. The follow appears.
Camera_Raw_6_3_updater.zip - ZIP archive, unpacked size 37,629,269 bytes
I assume I'm supposed click on this icon that looks like three stacks of
books and having the information next to it, Camera_Raw_6_3_updater.zip -
ZIP archive, unpacked size 37,629,269 bytes. After clicking on the icon, I
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
Application; From C:\Documents and Settings\(other info. I click on the Run
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.
Aloha

Countless .png files after converting pdf to dwg

After converting a .pdf file to a .dwg file using the export feature in adobe illustrator, I find that as many as 500 .png files come with the newly made .dwg after the conversion is complete. My question is, why do all these pictures come with the .dwg file and what would I have to change, settings wise, to no longer have to delete all of those photos? (i.e. how to export ONLY the .dwg file) I thank you all in advance for you help.

We can't know. We have no idea what the file looks like, how it was created in the first place or even what version of AI you use. And not to state the obvious: You are mistaken if you think that CAD-generated PDFs or DWGs only contain vectors, so for all intents and purposes this could be totally normal within the bounds of the format and how the file was originally generated.

Converting CR2 to DNG via script?

Hello,
I want to create a script which converts several CR2 files as DNGs (later to create a drag'ndrop-button for this script).
It's not possible to record this steps/these steps. Probably because of the "Camera Raw" module which Photoshop uses after opening a CR2 file.
Thanks.
Carlos

You might be better using the stand-alone free DNG converter from Adobe..
http://www.adobe.com/products/dng/
With this you can do a folder of raw files.
You could even create a batch file do do the convert IE:
Create a .bat file with something on the lines of..
For %%a in (c:\CR2\*.cr2) do "C:\Program Files\Adobe\Adobe DNG Converter.exe" -d c:\DNG %%a
This will process all cr2 files in Folder C:\CR2 and convert them to DNG putting them in C:\DNG
Another possibility would be to create a script passing the command line to the app.system() command (CS4/5)

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

Can´t view photos in full screen after loading photos to dropbox? what to do?, can´t view photos in full screen after loading photos to dropbox? what to do?

after loading photos to dropbox i can´t view them in full screen in iphoto ... i can only view them small ... when i click on them this sign "!" appears... do you know how to fix this????

If you're loading photos to drop box why do you expect to see them in iPhoto?
The ! turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
Remember: we cannot see your machine. There are 9 different versions of iPhoto and they run on 8 different versions of the Operating System. The tricks and tips for dealing with issues vary depending on the version of iPhoto and the version of the OS. So to get help you need to give as much information as you can. Basic things like :
- What version of iPhoto.
- What version of the Operating System.
- Details. As full a description of the problem as you can. For instance: 'iPhoto won't export' is best explained by describing how you are trying to export, and so on.
- History: Is this going on long? Has anything been installed or deleted?
- Are there error messages?
- What steps have you tried already to solve the issue.
- Anything unusual about your set up? Or how you use iPhoto?
Anything else you can think of that might help someone understand the problem you have.

Having problems with Bridge shutting down after saving photo in PS Cs5,,,,,,,,, Also when i attempt to update either PS or bridge get an error message in Adobe application manger "Error loading updater workflow"

Sorry for the late reply. My email firewall has become a little over zealous & sent a lot of my emails straight to my junk email folder, so I have only just now discovered your reply in my junk mail folder.
The only "don't open files exceeding xxx megabytes" instruction I can find in my Prefs, is in the Bridge Prefs for Thumbnails, & mine is set at 1000mb. The biggest files I handle are bigger than 200mb so I should be able to open a few, not just one.
However, this doesn't explain why I can open a psd format file of 180mb, close it, but then can't open a RAW format file of only 26mb immediately after.
I can open the RAW file only if I restart my computer - very annoying!
However, thanks for the advice about the video card & memory.
So, I'm still stuck as to what the issue is.
