Lightroom and DNG files

Can Lightroom 1.0 write data to DNG files?

It won't let you write them with a full-size preview though like the DNG Converter will.

I write both JPG and DNG files in the camera.   Camera is a Leica Monochrom.   Photo, unlike iPhoto, seems to ignore DNG files and only imports JPG files.   What am I missing here?

I write both JPG and DNG files in the camera.   Camera is a Leica Monochrom.   Photo, unlike iPhoto, seems to ignore DNG files and only imports JPG files when both are present on the SD card. JPGs are used for quick proofing on an iPad.    DNG RAW files are edited on a Mac Pro (2013).    Other than deleting the JPGs before importing images from the SD card, is there any way to force Photo to select and import only the DNG images?

Thanks Larry,
I did see the J stacked in the lower left of the thumbnails but couldn't figure out how to get to whatever is below it.   How do you select R?
I use an iPad to do quick proofs of my images.   A JPG is good enough for a proof ( dust on the lens, composition, blown out image, etc. ).   The iPad is JPG friendly and can load the images quickly.    Serious editing takes place on my Mac Pro with the DNG files.   I use the same workflow with the the Leica M 240.   iPhoto has been a quick and easy importer to the Mac capturing all of the metadata in the EXIF sidecar file ( location, date, time, camera settings, lens type). A quick scan in iPhoto for the "keepers" let's me export those worth editing to Lightroom/Bridge/Photoshop. I typically shoot 50 images from three locations in a normal day. If I'm lucky I'll get 1 worth real work to add to the portfolio.

Mavericks cannot read/preview lightroom 5 dng files. Sony a7R or RX100. However Canon 6D conversions are fine.

Mavericks cannot read/preview lightroom 5 dng files created from Sony raw files (a7R or RX100). However Canon 6D conversions are fine.
I have come across a couple of threads asking about this. It would seem that some raw files convert into something OSX can read, others (like Sony ARW) create dng files that OSX cannot read. Has anyone had any luck with this? I thought the idea behind dng files was that they were universal and not brand specific.
Any advice appreciated.

Camera raw and DNG files appear as generic icons

Camera raw and DNG files appear as generic icons instead of image previews (Bridge CS5)
What can I do ?

Hi Yammer.
First thanks a lot for taking your time to help me. I am really happy about it!
I will try to answer:
1)
I meant by having the Camera Raw.8bi placed in BOTH "C:\Programmer\Adobe\Adobe Bridge CS5\Plug-Ins" and in C:\Programmer\Fælles filer\Adobe Plug-Ins\CS5\File Formats" the ACR will be found in two versions - or rather in two places (I know the former shouldn't be, but it solved my preview problem).
2)
YES - I do have tried twice starting the Adobe Bridge holding down the Ctrl-key and ticking the two (the third was greyed out but ticked anyway) and with no help.
3)
I have tried to do the *.8bi search you suggested, and this gives me the following dump - absolutely with a few more entries than yours. Some are like doubled.
Do you think I can just delete these?
Kind regards, Jan

Why have all my Lightroom and Photoshop files just developped an awful colour shift? how do I correc

Why have all my Lightroom and Photogshop files suddenly developped an awful colour shift when they did not have this a week ago? I can open them in other applications and they view correctly. How can I correct this in Lightroom? HELP urgent!!

Antonia,
Probably your monitor profile is corrupt.
If you're on Windows, see here:
http://www.lightroomforums.net/showthread.php?14070-How-to-assign-an-sRGB-ICC-Profile-to-y our-monitor-%28Windows%29
If you're on a Mac, you'll need to try something similar to set your monitor profile to sRGB. NOTE: this is merely a temporary fix. You need to acquire a hardware calibrator (decent ones can be had for around $100) and calibrate your monitor with it.

Why don't my Lightroom 4 DNG files show up correctly in Picasa 3.9?

Although I have really learned to love Lightroom I still like the elegant, quick and simple Picasa for certain tasks -- uploading photos to my Google web albums, setting screensaver and desktop photos, etc. But I think that Lightroom 4 made some changes to the dng format which means that when Picasa imports the files into its database the dng files (not the accompanying jpg) come in squished and banded. Does anyone else find this problem? Is it something that Lightroom can fix or can they communicate with Picasa to solve it?
I know that given Lightroom's power and fantastic ability to "develope" photos, it might seem unnecessary to use Picasa and I do admit that I don't use Picasa frequently, but still it does have its uses and I would like to see the two programs play nice together. I am using Windows 64 bit, Lightroom 4 and Picasa 3.9 and phy camera is a Nikon D3100.

When you convert a raw file to DNG there are some options such as adding fast load data (prolly want to turn that off for compatibility reasons) as well as Lossy Compression (you don't say whether or not you have selected that option). For Picasa to be able to access your DNGs, the odds are you'll have to make sure you select an older DNG spec such as 1.3 instead of the current DNG 1.4 spec used in LR4. Other than that, you may need to wait till Picasa updates their software to deal with the new DNG spec.

Lightroom and DNG compatibility?

Will Lightroom read DNG converted from RAW from a camera that Lightroom doesn't support?

> "Barry what do you mean by converter? I am talking about taking a CR2 image and converting it to a DNG file."
I was talking about converting raw files in general to DNG files. (Not just CR2s). I was NOT talking about "raw conversion".
Adobe provide ACR, Lightroom, and the DNG Converter. They can all convert CR2s to DNGs (among other things). (They are all DNG converters and all raw converters, sharing core code).
Hasselblad-Imacon provide FlexColor which can convert their raw file formats to DNG. Pentax provide PHOTO Browser which can convert PEFs to DNG. Better Light supply ViewFinder for their scanning digital backs.
Then there are amateurs to who supply (typically free) converters for niche and minority and unofficial raw file formats to DNG: raw2dng; DNGForPowershot; SMaL to DNG; eMotionDng; etc:

Strange artifact in some NEF and .dng files

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

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

Powershot G15 and .dng files

Why can't I import and edit RAW files directly from my powershop G15, without converting to .dng files? I am using Lightroom V 3.6.

SarahCD42 wrote:

That's why.
G15 came out after Adobe quit maintaining Lr3.
Yes, Adobe could keep retrofitting old software with new camera support, but they don't.
Note: if they did, the money to do so would be coming from users who pay to upgrade, and only benefit users who haven't paid to upgrade.

Virtual copies and DNG files

I may have completely misunderstood something, but I thought the metadata in a DNG file was contained within the file. The virtual copy function in LR1 is very interesting for making different versions of the same image, but if the image metadata for the virtual copies is in XMP files, does this preclude the use of this function with DNG files?
Martin

Thanks. So the XMP metadata block in a DNG file will just contain any non-destrictive edits made on the original file. The information about any edits in virtual copies are then in accompanying files (XML?). Or is this information only contained within the Lightroom database?
I am just trying to understand how the information is stored and if it is accessible to other applications.

AE stopped to open cr2 and dng files, PS still works

Hi
I have a mac book pro 16gb OS 10.9.2 and worked over 6 months with AE and Photoshop CS6 opening and working with cr2 (Canon 5dmk3 raw) and dng (converted from magic lantern) files.
all went well. For no apparent reason (maybe any kind of update?) my AE does not recognize these files anymore. They just show up grey and not selectable in the open/import dialog.
I can still open them using photoshop with the well known dialog box for raw files. so somehow the raw importer seems to work? Tried adobes dng converter 8.4 but converted files do still not open.
Did someone encountered the same problem and found a solution? Thanx very much for your help!

Develop Settings and DNG files...where is the info stored?

I just converted my Nikon NEF files to DNG. Previously I saved all changes I would make to my photos in the XMP sidecar files. I'm confused how things are working now because I thought those same changes would be saved to the DNG file.
Now that I use DNG files, when I make adjustments to the develop settings in LR, are those changes ONLY saved to the catalog? Or is there a way to save them into the DNG file so I can bring them to LR on another computer and see my changes? I feel like when I had XMP files before with my RAW files, the develop settings were saved there in addition to the catalog, so my changes came with me... Maybe I'm wrong though.

>Each of my RAW files also has a corresponding 10KB XMP file.
These are known as XMP sidecars and are applicable only to proprietary raw files (e.g. CR2, NEF, etc). Adobe have a policy of not writing anything back into a proprietary raw file (exception being date/time stamp) because the proprietary data tends to be undocumented. The XMP sidecar provides a safe documented means of storing the metadata corresponding to each proprietary raw file.
> I understood that the metadata is written to the file itself, but apparently only to DNG JPG and Tif files - right?
Correct
>So, if this is correct, then all metadata except that originally written by the camera is saved in the XMP file on RAW files?
For proprietary raw files the metadata is written into the XMP sidecar, but for the other formats you mention it's written "into" the XMP block of the actual file.
> Is the XMP file the information used by the Catalog? If I open a RAW image in Photoshop CS3 will the XMP information be read and applied when the file opens?
Yes to both questions

Lightroom and CR2 Files

I have just downloaded lightroom and it cannot read my CR2 files downloaded from iPad. Any ideas to solve problem appreciated

Is this the process you used?
"Getting Photos off the iPad
After you have transferred photos to your iPad using the CCK, you may be wondering how you get them back off the iPad.
You do this by connecting the iPad to a computer using the standard sync and charge cable that came with your iPad. When connected this way, the iPad appears as a removable drive in your file browser, just as if you had connected a camera or a card reader.
You can then copy the files over to your computer using the default file manager, or using the import function within your desktop software such as Lightroom or Bridge. The raw files will be just the same as if you can transferred them from your camera or storage card."

Mac mini good for photoshop, lightroom and large files?

Hello all,
My brother finally wants to switch from windows to mac and asked me for advice. He is a young photography professional so his primary need is to run photoshop, lightroom and be able to use large RAW files and 100+ MB photoshop files.
He still has a 27" high resolution screen, so my first option to look at is the Mac Mini with the 2.7 GHz dual core i7, 8GB of ram and the standard 5400 rpm drive (as SSD is too expensive). Is this machine capable of handling the above mentioned things? I think that the processor and memory are more than enough, but i have my doubts about the videocard, since 256 mb of video memory is not that much in these days..
In the future he wants to buy an iMac or Macbook Pro, but for now that's still a little to expensive. Although, if the mac mini is not that good, he has to decide whether to wait a while and then buy an iMac or something.
I hope that anyone can give us some advice:-)
Kind regards,
Mark van Dam

Thank you everybody for all the replies!
First off, I think we'll wait what the 11th of june will bring us, hopefully a new mac mini. As Michael Wasley stated, the glossy imac screen isn't going to work for him. So that brings us to a Mac Mini or Macbook Pro. I'm using the macbook pro myself for the last couple of years and i'm a great fan of it's capabilities.. but my brother prefers a fixed 'computer' and not a laptop..
At this point i think he's going to buy (the new?) mac mini (and use his own screen), upgrade the RAM to somewhere between 12-16 GB, possible get a SSD drive and for sure get the biggest i7 processor available.
Hopefully that will get things running.
Kind regards,
Mark

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!
