Camera Raw, DNG Converter 4.6 now available

Camera Raw 4.6 and the DNG Converter 4.6 has been posted to for Mac and Windows.  This release adds support for raw formats from the following 15 camera models:


  • Canon 1000D (Digital Rebel XS/EOS Kiss F)
  • Canon 50D
  • Fuji FinePix IS Pro
  • Kodak EasyShare Kodak Z1015 IS
  • Leaf AFi II 6
  • Leaf AFi II 7
  • Leaf Aptus II 6
  • Leaf Aptus II 7
  • Nikon D700
  • Nikon D90
  • Nikon Coolpix P6000
  • Olympus SP-565 UZ
  • Pentax K2000 (K-m)
  • Sigma DP1
  • Sony A900


Lightroom/Camera Raw PM Tom Hogarty notes, "You won’t find this update listed on our traditional Camera Raw page as we are moving quickly towards updates specific to the Camera Raw 5 and the CS4 release. For our Lightroom customers, similar camera support can also be found in Lightroom 2.1 currently available on Adobe Labs as a Release Candidate."


Note that if you’re not using CS3, the free DNG Converter can make your files compatible with other DNG-savvy software (not to mention smaller and more portable as well).

Make instant JPEGs from raw files

Michael Tapes from has teamed up with the guys from Imagenomic (known for Noiseware) to create the very cool–and free–Instant JPEG From Raw utility.  It doesn’t interpret or convert your raw image data; rather, it just pulls out the JPEG preview embedded by your camera*.  It can optionally downsample these JPEGs to a lower resolution as well.  Check out a quick video demo of the tool in action.


I think there are some especially interesting possibilities here with DNG.  As you may know, when you edit the settings of a DNG file using Camera Raw or Lightroom, you can opt to update the embedded JPEG data as well as the settings themselves.  This means, as photographer Peter Krogh likes to say, that a DNG file can serve as a “job jacket”: a container that holds your negative, your development instructions, and your print.  The IJFR utility provides an immediate way to extract not just the data your camera captured, but the data as processed per your instructions.


*Worth another mention: Bridge CS4 now offers the ability to browse just embedded JPEG data, bypassing the raw processing stage to enable quick initial passes through a shoot.

Camera Raw 4.6 available on Adobe Labs

The Camera Raw 4.6 and DNG Converter Release Candidates (RC) are now available on Adobe Labs.  As Lightroom/Camera Raw PM Tom Hogarty explains,


The “release candidate” label indicates that the plug-in is well tested but would benefit from additional community testing before it is distributed automatically to all of our customers. The Camera Raw team would like the community to help verify the quality of the plug-in through normal usage as this will ensure that the plug-in is tested on a diversity of hardware and software configurations not available internally at Adobe.


This release includes official camera support for the following cameras:


  • Fuji Finepix IS Pro

  • Nikon D700

  • Nikon D90

  • Nikon Coolpix P6000

It also adds preliminary (unofficial) support for these new camera models:

  • Canon Rebel XS

  • Canon 50D

  • Olympus SP-565 UZ

  • Sony A900

  • Sigma DP1


Tom explains a bit about what unofficial support means later in his post.

Photos in motion; DNG sprouts wheels

  • As you probably don’t need me to tell you, Canon has just announced the 5D Mark II, complete with the ability to record HD-resolution (1080p) video.  This follows on the heels of Nikon’s D90, itself capable of 720p video capture.  My initial thought was that DSLRs capturing video is kind of like dogs walking on their hind legs–not done well (e.g. no autofocus), though interesting to see done at all.  Nikon’s sample videos, however, have gotten me thinking about the possibilities, and film effects pro Stu Maschwitz sees lots of promise.  (He calls Canon’s decision to shoot at 30fps instead of at 24 "almost unbearable," however.)
  • On the other end of the tech spectrum, I’m a big fan of the little Flip video camera.  Now a guy named Reid Gershbein has given a tilt-shift appearance (how, he doesn’t say) to footage from the wee cam.  Hmm–this may motivate me to try applying Lens Blur as a Smart Filter on video using Photoshop Extended.
  • Ikonoskop’s rather potent-looking, weirdly named A-cam dII is, it would appear, first to support DNG for motion capture. "The buzz at IBC is DNG," they write, "so people seem to understand and start to follow our lead in DNG together with Adobe." [Via Scott Sheppard]
  • Interesting video of an SLR: Nikon D3 Shutter Release in Super Slow Motion. [Via Zalman Stern]
  • Photojojo’s got some ideas on making flipbooks from your video content.

The DNG Profile Editor: What's it all about?

When we look back at how things changed with the arrival of Lightroom 2, I think the new DNG Profile Editor (presently kind of a sleeper technology) will stand out as transformative.  The technology was largely developed by Eric Chan, a bright young guy on the Camera Raw team (and aspiring photographer).  I’ve always found his explanations lucid and highly readable, so I’m delighted that he’s written a guest blog post on the subject.  Enjoy.  –J.


Hi everyone. My name is Eric Chan and I’ve been a Computer Scientist at Adobe since February, which doesn’t exactly explain how I ended up on John Nack’s blog. [People often wonder how they ended up here…  –J.] Well, John kindly invited me to share some thoughts on the new color profiles for Lightroom 2 and Camera Raw 4.5… "Whoa, hold on there!" you say, "New profiles? What new profiles? I didn’t see any new profiles!" Ahh, that’s because the new profiles are currently undergoing a public beta and aren’t shipping directly with LR 2 and CR 4.5. Instead, they’re available as a separate download from the Adobe Labs web site. Why a public beta? Simply because there have been many changes under the hood, and we want to give folks a chance to try the new profiles and provide feedback before we bake them for final release.


But I’m getting ahead of myself here. Let me backtrack and give you the big picture first. As it turns out, there’s quite a bit more going on here than just a new set of color profiles.

Lightroom, ACR support D700

A number of people have written in to ask when Lightroom and Camera Raw will support the brand-new Nikon D700.  Good news: they already do–unofficially–in Lightroom 2.0/Camera Raw 4.5.  Unofficial support simply means that you can view and edit D700-generated NEF files normally, but because the camera is so new, Adobe QE folks haven’t tested it to the point that they feel comfortable declaring official support.  The DNG Converter can convert D700 NEFs so that they can be used in LR 1.4, Photoshop CS2, and other DNG-enabled tools.


Note: LR2/ACR 4.5 add official support for the Olympus E 420 and E 520.

A pair of video interviews: DNG to Little Shop of Horrors

  • I stepped out onto the Adobe basketball court the other day to record a brief interview with Frederick Johnson from the Lightroom team.  If you can deal with the squinting and excess of "you knows" (I know, I know… y’know?), you might dig out some salient bits.  (And hey, you hadn’t thought of They Live in a while anyway, right?)
  • My pal & fellow Photoshop PM Bryan O’Neil Hughes was in Florida last week and appeared on Photoshop User TV with Scott Kelby and crew.  Bryan focuses particularly on the DNG format.  He notes, "I wish I’d mentioned that the DNG Converter allows people who haven’t upgraded to realize the benefits of raw with their newer camera in older copies of Photoshop." (Also–seemingly apropos of nothing–yes, I am a very angry man. ;-))

Camera Raw 4.5 RC now on Labs

Lightroom/Camera Raw PM Tom Hogarty has announced that the Camera Raw 4.5 and DNG Converter Release Candidates (RC) are now available on Adobe Labs.  He writes,


The ‘release candidate’ label indicates that the plug-in is well tested but would benefit from additional community testing before it is distributed automatically to all of our customers. The Camera Raw team would like the community to help verify the quality of the plug-in through normal usage as this will ensure that the plug-in is tested on a diversity of hardware and software configurations not available internally at Adobe.

This release includes new camera support for the Olympus E 420 and E 520 camera models.

Please provide feedback on your experience with the Camera Raw 4.5 plug-in and the DNG Converter on the Camera Raw User to User forum.  Lightroom customers who would like to use the new support provided for the Olympus cameras can download the DNG Converter release candidate and convert your raw files to DNG before importing them into Lightroom 1.4.1.

DNG codec for Vista available; DNG spec updated

Adobe has posted release candidate (i.e. feature-complete beta) of the Adobe DNG Codec for Microsoft Vista.  This free download enables Vista users to view DNG files in the Windows Explorer and Photo Gallery.


The posting coincides with the DNG Specification being updated to version 1.2.  Tom Hogarty writes,


This update addresses several industry requirements for the DNG format including the formalization of the concept of a "camera profile" and a metadata tag to validate your image data.  The definition of a camera profile for the DNG format as well as the allowance for multiple camera profiles to be embedded in a single DNG file will provide the industry with the ability to characterize raw data in an efficient and standardized format.  (Think ICC profiles, but for raw data.)


Check out the rest of Tom’s post for more details on the changes.  Developers can grab the updated DNG SDK here.

DNG submitted to the ISO

"The DNG format was supposed to be the future, an open standard for RAW files that every manufacturer could use," writes Digital Photo Pro’s Dave Willis.  "Here’s a look at how the revolution has panned out."  Dave talks with my boss Kevin Connor about the problem that gave rise to DNG:

"Our philosophy on this from the beginning, sort of my personal belief," continues Connor, "is that eventually the proprietary system is just going to break. When we came out with the first camera RAW plug-in, we were supporting around 25 cameras. We’re now supporting more than 175 cameras—in other words, more than 175 different file formats. And when you’re talking about images, people don’t want to keep those images for just five or 10 years. Professional photographers want to know those images will be fine for 50 years—100 years—from now. If you think about the rate of new-camera introductions, how many new file formats will there be? A hundred thousand? It just seems that it’s going to reach a point when it becomes unmanageable."

It’s true that we haven’t yet seen big camera vendors like Canon and Nikon adopt DNG, though maybe we’ll see more progress now that DNG has been submitted to the ISO as a vendor-independent standard.  In any case, the format is providing real-world benefits today:

  • Converting to DNG saves disk space and eliminates the need to use separate sidecar files for raw settings.  (I knocked 1.5GB off the 7GB of photos from our wedding photographer.)
  • Because of these benefits, customer feedback indicates that 40% of Lightroom users are converting to DNG on import.  (It’s a one-click set-and-forget option that’s also available in Adobe Bridge CS3.)
  • DNG lets Adobe support new cameras in older versions of Camera Raw without having to constantly revise and test those versions.  Photographers and use the free DNG Converter (Win | Mac) to process their proprietary raw images to DNG.  The upshot is that we can spend our time building good new functionality instead of updating old software.


[Update: I neglected to mention that yes, Adobe will be providing a DNG-viewing codec for Windows Vista, making it possible to view DNG files right within the operating system. Expect this free download to be posted soon. –J.]
