Lightroom and Samsung GX-10 DNG files

Hi
i've got a problem with LR and the samsung GX-10 DNG file format.
It semmes that LR does not read correctly this Raw file
at the begin of the rendering, the image has good colors but they change at the end of the rendering. Colors are more dark and finally the photo is not nice.
I've done the same test with raw therapee and the rendering is better.
Have you got informations about.
It's such a pity because LR is great. i like it !
regards

yeah,, I know about raw data , and yes, wrong or not, the rendition of gx-10 pictures are very "bad" compared with other softwares and with my eyes, and I think that you can understand when i said "bad" no?, there aren't a wrong or correct in raw color but the people speaks about the wrong o correct colors all the time, i think that you understand when speak about bad colors, a bad WB , etc.
I know that i can make my own profile but is not easy, to generate a good profile I need a Macbeth ColorChecker or something like that for example and precise sources of light (like a tungsten) and taking account about that samsung cameras are "clones" of the pentax ones and that samsung shoots in DNG format (and not a propietary raw format) seems easy solve the problem about color interpretation of GX-10. With time I will buy a color-checker and try, but would be great a correct interpretaion of the own samsung colors
PD2: When i know about samsung "adobe-DNG" capacity, i didn't expect have problems with adobe soft and color intrepretation or something like that.
PD: Sorry , I don't speak english well, and so I can't express me very well , only basics

Why won't Lightroom 3.3 send a dng file to Photoshop CS5?

I am using a Windows 7 64 bit platform, Lightroom 3.3, Camera Raw 6.3 and Photoshop CS5 also 64 bit. I have my photos (from a Nikon D3100) in dng format but when I try to open it in Photoship using the Edit in command to send it either as a dng file or a smart object I get a notice that the file couldn't open because Photoshop couldn't be opened. In fact Photoshop does open (or it is already open). Sometimes, the file will eventually open in Photoshop, but it takes several minutes -- like 5 or more, other times it never opens.
Can anyone offer any suggestions or help?

Quote <Is there a setting LR or on the camera that I can use to allow LR to recognise (and render) the NEF file from the camera?>
No. LR will only show the thumbnail rendered by the camera,if it is possible. The better practice would be to download the files from the CF/SD card using a reliable card reader, this would be more efficient/faster and reliable. (use the camera to take photographs, rather than have it attached to the computer.)
A LR generated preview will only be rendered after the import of the NEF.

Lightroom 32bit mode for 32bit DNG files

When I open 32bit (floating point) TIFF files in Lightroom (5.7.1) it opens them as expected - in 32bit mode - and allows me to adjust the exposure slider in the range of -10ev to +10ev.
However, when I open 32bit (floating point) DNG files, it opens them in 16bit mode and allows the exposure slider to range only from -5ev to +5ev.
Does anyone know why it works this way?
Is there a way to open 32bit DNG files in 32bit mode?
Note that a 32bit DNG file can be converted to 32bit TIFF using "dng_validate.exe -3 <output.tif> <input.dng>"
This way I can convert my 32bit DNG files to TIFF, but I lose the control over WB and I end up with huge TIFF files.
I'm obtaining my 32bit DNG files using HDRMerge. This can be used as a reference:
https://dl.dropboxusercontent.com/u/21642925/PC211276-211280.dng
I also tried 32bit DNGs that were created by CeroNoice and I get the same result (LR opens them in 16bit mode rather than 32bit and restricts the exposure slider to -5ev - +5ev).
It could be that HDRMerge or CeroNoice do not produce the DNG correctly. However, I tried to run the output of HDRMerge through a DNG to DNG conversion using Adobe DNG Converter and it didn't help either.

Thanks for taking a look at this.
I think that converting 32bit tiff files to dng only changes the wrapping. So in a way it's understandable that they are opened in 32bit mode. I still don't understand why normal 32bit dng files can't.
Thanks for the top about the GND filter. I thought about using a brush all over the frame, but a GND can also be used. I suspect that if LR opens my dng file in 16bit mode than it uses a narrower pipeline for the tone curve and color manipulation so the result will be inferior compared to a 32bit tiff file (developed with the same settings). That's why I'm trying to find a way to open the dng files directly in 32bit mode.

Lightroom and Sony A700 Raw (ARW) Files

I shot all pictures in ARW format. A number of the shots are at mid to high level ISO numbers. The shots above 400ISO are extremely noisy(both cloro and luminance)When I use the SOny supplied software
the same pictures noise level is significantly reduced. I have read on several other forums that ACR in lightroom is "messing up" the ARW files. This appears to be true. I use lightroom then CS3 to process my shots. The use of the Sony softweare complicates my workflow but at this point I am forced to do this. Is there any relief in site for this concern. Really want to combine everything into one system. By the way CS3 Bridge is not much better.
Any assistance would be greatly appreciated.

I have your lighting right here, JM.
It's quite clear you know nothing about shooting African Cichlids, the most colorful freshwater fish in the world.
These fish are "mbuna", they live in rocks, caves, and along rock faces and ledges. They are used to living many meters deep so the best fish always take up territory towards the bottom of the tank where the best structures are, where the light is most dim.
In this 120 gallon tank is well over 500 pounds of structure which consumes most of the space in the tank.
In many of the photos you will notice rock structures around the fish as the tank consists of a hundred or so ledges and caves.
African Cichlids are the smartest fish in the world and they even learn who is who...they are not ordinary fish.
No matter how much light you throw on African Cichlids it usually does not cure the problem since they spend most of there time peeking from, and hanging under structures. Shadows and dark areas are cast throughout the tanks due to the structures.
Not to mention you must use the lighting already available in every public tank in the business, not to mention fish vendors usually cannot add lighting to their tanks either.
That leads us to use high ISO when we must.
Here are a few Sony A700 test shots made with 3 custom temp 4 ft 40 watt tubes in a deep 120 gallon tank.

Here are a few old shots of mine when I used my custom built and designed setup w/6 custom temp 40 watt tubes made to fit a standard 55. Notice structure galore...it's like an urban housing complex in the mbuna tanks. I can shoot fish with a good pNs setup fairly well with this amount of light. Not many people anywhere get this amount of light on their tank, trust me.

I shot Minolta, and then Konica Minolta, and now Sony has bought KM, so Sony is the one making the bodies for our glass now.
Many of us will not give up image stabilized primes (body SSS) so we stay here. All lenses gain 2-3 stops on the Sony...A700 has top notch DR and great high ISO so most of us are not interested in Canon at the moment.
This thread is here to help the Adobe team make ACR better, please stop interfering with your brand bashing speaks.
Thank you.

LR4 and develop settings in DNG files

I spent a day developing a set of DNG images in LR4 and then used Bridge to rename all the files. When I sync'ed the folder in LR the develop settings in the DNG files were not there, all zero'ed out. I thought the develop settings were stored inside a DNG file by default? Do I need to tell LR to do that? I don't see where that setting might be.

In Lr, I think the default is to store develop settings in catalog only.
To store in DNG files, hit Ctrl/Cmd-S, or enable auto-save xmp in prefs.
Edit Menu -> Preferences -> General Tab -> Catalog Settings -> 'Automatically write changes into XMP'.
I prefer the manual method for a variety of reasons, but others prefer the automatic method (mostly so they don't forget I guess).
Cheers,
Rob

PSE 5 and cataloging RAW/NEF/DNG files?

Hi!
Now, I use the PSA 1 and I wish to upgrade to PSE 5. For long time I've been using .JPG for archiving. After I change my camera do DSLR, I need to catalog my .NEF files (Nikon D40).
Can you show me yours workflow for that files? I want to archive in .NEF format or in .DNG (after conversion). I need to add IPTC captions/tags and keep it in files, not in "external" database.
I planned to first make DVDs with my RAF files, then catalog it off-line in PSE5. Can I do this?
Thanks for answers! :)
Mateusz.

Mateusz,
Everyone has a unique way of doing things. I would recommend that you
download the trial software and then ask questions based on what you would
like to do when you see the application. Otherwise, you might find that
anything we suggest you here, will change once you see what you can do in
the application.
Cheers

Problem diplaying dng files converted in Lightroom

When I import my RAW files into Lightroom, I convert them to .dng files. They display just fine in Lightroom. However, when I try to open them in Irfanview or Thumbsplus, the image is broken up into broad hoizontal bands with some of the image missing betweeen the bands. I suspect that this is a windows problem since it happens with two different windows applications. Here is an example.
Anybody have an idea where this error comes from?
Nat

Thanks for your help. I did some searching on the ifanview forums. According to somone there, this problem can be avoided by disableing "fast load embedding" when importing RAW files. I have not been able to confirm this as I have not yet figured out how to import them without "fast load embedding". However, it seems like a nice feature that I don't want to disable. I guess, for now, I will just import my RAW files and not convert to .dng.

I'm considering buying CC LR/PS package. My camera is Sony a7 - raw ARW. I've been editing using PSE10 and ver 8.7 of the external Adobe DNG converter. Will I be able to open the DNG files in LR with the edits preserved? Will I be able to open the PSD files in LR with the edits preserved? Any import/catalog etc issues between PSE10 and LR?

Lightroom has no problem reading DNG files. Whether the edits you have done to the DNGs you have originally edited in Photoshop Elements 10 I'm not sure. ACR edits made to DNGs are saved in the DNG file itself, as apposed to a XMP sidecar file, so LR should see those edits. At the worst you will get an exclamation mark in the upper right hand corner of the imported DNGs and clicking on that exclamation mark you will get a dialog box asking you to either import settings from disk or overwrite settings. you would select import settings from disk.

Lightroom not finding DNG files in the folder

I am using Lightroom 2.5. My library includes a folder with approximately 5000 images which is located on an external hard drive as is my Lightroom catalog. I use the external dive because it is part of a RAID 1 array to backup my images.
My problem began when I used Lightroom to convert the 600 RAW files in the folder to DNG files. Prior to the conversion, the library tab showed that there were 5000 files in the folder. After the conversion, the library tab shows that there are only 4400 files. The DNG files are actually there but Lightroom will not recognize them. I can use windows explorer to see them and that there are 5000 files in the directory.
I have tried to synchronize the folder, but it did not help. I have also tried to write metadata to the files to make sure that was not the problem and it was no help. As a test, I also copied the directory to my local hard drive and imported that into Lightroom. That folder has the correct 5000 images, but of course non of the ratings that I had applied to the 5000 files to organize them so the local folder is useless.
Can anyone suggest a means of convincing Lightroom that it should recognize the missing DNG files that are actually there?
Thank you.

John,
Thank you for your suggestions. I do have filters off.
I started up Lightroom today and again, the Folders tab only showed that the folder had 600 files which corresponds to the missing 600 DNG files. Furthermore, in the grid view, only the 600 DNG files were appearing. But, after a minute and without my input, Lightroom loaded up the 4400 JPEG images into the grid and the DNG files disappeared both from the file count and the grid view.
When I look at the All Photographs folder in grid view, I can find the missing DNG files so they are in the All Photographs folder.
I did as you suggested and I optimized the catalogue. Now when I launch Lightroom, I see the missing 600 DNG files in the grid view and the file count for the folder. But that only lasts a few seconds before the 4400 JPEGS appear and the DNG files disappear. So the optimization made the loading faster as it should, but did not help Lightroom to find the DNG files.
Now when I try to synchronize the folder, It does show that there are 600 files to be added. However, synchronization does not help and DNG files are still missing.
I can see the DNG files in a folder called “Already in Catalog” from when I tried to synchronize the original folder. After optimizing the catalog, I told Lightroom to write metadata for the DNG files. Once I did that, some of the missing DNG files did appear in the grid view of the original folder (but not all of the 600 missing files). However, the library still only shows 4400 files in the folder.
One last oddity. When I change the sort to “user order” from “capture time”, I see only the 600 missing DNG files in the grid view. The 4400 JPEG files are gone. But when I change the sort back to capture time, the JPEG files and the few DNG files are there again and most of the DNG files are gone.
This bugginess is only occurring on the external drive. The same files saved to the local hard drive all appear in the file count and the grid view.
Thank you.

LR 3 and DNG files created and edited in LR 2

Workflow had been to import Nikon NEF files, convert to DNG in LR2, do my edits, and save the data within the DNG file. Tried to upgrade to LR3 tonight, using the trial version while I wait for my package to arrive. The catalog migrated just fine, with the exception that the edited DNG files were ignored.
DNG files that had not been edited seem to have imported just fine. But what fun is that. I need access to all my DNG files to continue the editing that I had been doing in LR2.
I verified the DNG files were still on the computer. I then tried to sync one of the folders I knew had edited DNG files in it that hadn't been migrated in the catalog import. LR 3 refuses to acknowledge the files exist, and doesn't give me the option to import them. :-(
Is there some option or preference I need to set/reset? Is this a known bug or issue? Is there a workaround?
Computer is a Intel Quad Core with 4 GB running WinXP Pro.
Thanks in advance,
- Arved

I don't remember what the settings were when I imported the catalog. Whatever the defaults were.
Whatever happened during import, I should still have the option to add the files when sync'ing a folder? But I don't.
Neither LR2 nor LR3 will allow me access to the edited DNG files now. I've erased and am rebuilding the catalog (all pertinent info was written to sidecar and/or within the DNG file, so I'm not anticipating any problems with this. It's showing the expected 27,000+ files being imported). I think I'll try building the LR3 catalog the same way when I fire it back up, once I'm sure I'm back up and running in LR2.
Thanks for the quick response!

Dng. files from LR to PS CC ok Can't open in Camera Raw?

I have LR 5.7 and can edit my dng. files in PS CC but I can only get Camera Filter not full camera raw w/ all the tools. I am a PC user, BTW.
How do I open full Camera raw for a dng. file?
Thanks, very frustrated.
Chris

Because it was edited in lightroom first, photoshop knows enough to bypass camera raw since the controls are identical. If you open the dng file using the normal way like any other format, then it would open in camera raw first.
Keep in mind if you already did any editing in lightroom, those edits needs to be saved to that dng file before you can do the above otherwise camera raw and photoshop will not see the edits you did.
To save a file in lightroom select the file in the library and use ctrl-s to save.
If you do the above, lightroom will not automatically see the changes done in camera raw or photoshop. In library view there will be an icon in the thumbnails corner. This appears when changes to the metadata do not match that of lightroom's database. Clicking the icon should provide a dialog box asking if you want to update lightroom or leave it unchanged.
If you do a folder full, you can sync that folder to update all of them. Keep in mind syncing overwrites your changes in lightroom so make sure that is what you want to do.
I personally try to make it a habit to save all the images from lightroom, just so I don't get any surprises when syncing. There is an icon in the corner of those that need saving.

Lightroom and Using the editor in PS3

On using Lightroom to open up a DNG file file in Photoshop CS3 I receive the message "Lightoom is unable to prepare the selected file (file address) It will not be opened". I have read the other links in this forum and have tried the solutions offered with no success. I have plenty of space on my hard drives and I use the default folders to store the images.
Does anyone have any other ideas why Lightroom cannot open a file which it has saved and provides the correct file path?
Currently I am using a work around by using Photoshop manually to open up the DNG and saving as a TIFF. I then drag and drop this into Lightroom to import it into the catalogue. But what a fuss. Lightroom can then open the TIFF in Photoshop, but I am unlikely to want to do this.
Any suggestions gratefully received.

Although Jao's tip enabled me to open my TIFF file in Photoshop I wasn't able to "save" the file in Photoshop but could only use "Save as" which was still a hassle. Photoshop was reporting "Could not complete your request due to a programe error. It was also reporting an error under File/File Info in the drop down menu.
It would seem that Jao's tip simply worked round the initial problem rather than curing it as in both cases the problem was with Save, but I could Save As. It appeared that the problem was around the metadata and after much experimenting discovered that the problem was due to editing the capture time on my imports in Lightroom. I took all the times back several hours and did this before I adjusted the image in Photoshop. I had tried to set back the time to its original capture time, but this did not help. The solution was to delete all of the imported files and re-import. I then edited the files in photoshop before changing the capture times. However, I must admit that I am now reluctant to change the capture times at all - which isn't a great loss.

How to import multiple DNG files into Premiere

I want to import multiple raw DNG files from a 2.5K blackmagic camera. Each clip is recorded in a separate folder:
I can import each clip separately by selecting its folder and clicking on a DNG file, but -for obvious practical reasons- I would like to import ALL clips at once. However, when I try to do so, Premiere does not import the clips. Instead, it imports each folder, and within them there is not one single clip, but as many clips as DNG files compounded that particular clip. In other words, if the clip had ONE HUNDRED DNG files, Premiere imports that clip ONE HUNDRED times, not just once:
In this image, each file contains the ENTIRE clip, not just a DNG file. Is there a workaround for this? Otherwise, DNG files must be imported one by one, which of course makes the workflow much more difficult.

Jim, when selecting the blackmagic2 level, the only available option is File Directory:
This doesn't happen with RED files, where you can choose between File Directory and RED from the first level. Unlike blackmagic's DNG clips, RED files can be imported all at once, so maybe that's the whole problem:
And yes, Source Settings are available for RED files, whereas they are not for DNG (only basic information, not raw manipulation):

How to make colors looks same in Lightroom and Photoshop?

The colors of JPGs with sRGB colorspace are displayed differently between Lightroom and Photoshop and other image view applications.
I edited RAW images in Lightroom and export them to JPG files with sRGB colorspace, but their colors are eventually different from what I saw in LR.
(I set ProPhoto as the colorspace for my Photoshop.)
Is there anything I can do to solve this problem? Or maybe to reduce the color difference?
What is the best I can do to manage colors for those images that I want to share on the internet?
Thank you !!!

If colours look different between two colour managed applications such as LR and PS then you have either not calibrated your monitor at all or are using a corrupt monitor profile.
If the former you require a calibration device, such as a Spyder (lots of other around). If the second then re calibrate.
In the meantime you can set your monitor to use a colour space such as sRGB as a profile. This is not a solution, it is a temporary fix. Using a colour space as a monitor profile is not colour management, but will at least make the colour appear the same on your monitor.
There are some useful links concerning colour management and LR here you may wish to read.

Option to store xmp metadata outside of DNG file

This would serve to improve differential backups, as the xmp file format is text based and easy to tell differences.

Walt,
No, you totally misunderstood what I meant. I'm not talking about LR catalog backups, I'm talking about backing up scores of dng files completely outside of LR, from the OS or some other external tool. With my suggestion, the xmp file would be right next to its dng file, and i would be backing up the whole directory hierarchy that hold my files. One of the benefits of LR over Aperture is that I can access, manipulate, and/or backup my files outside of the app rather than having them locked up in a vault which must be backed up in one huge blob.
If I change the brightness of 500 dng files using LR, then back up all my dng files using rsync (for example), I will be copying 500 large binary files around. If my edits were saved in separate text files (xmp), then my backup program could only copy the DIFF of each of the text files (one line added to each file, so one line, or five in a normal unified diff format, is all that needs copied around). This would be exponentially faster.
Embedded xmp edits is not a good practice, from an OS-level backup point of view. Since not everyone will agree on that, I'm asking for a checkbox option - I'm fine with it being embedded by default.
With xmp data being stored inside the dng file, and LR changing the dng file every time I edit something, LR is hardly non-destructive from an OS-level point of view when dng files are used.
No where in the spec does it state that xmp changes data MUST be stored in the dng file. I'm simply asking for the option to store that data outside of the DNG file, so that the dng file only needs backed up once or rarely, rather than every time I make an edit.
