DNG History and Summary

Barry Pearson has recently posted a number of blog posts outlining his experience learning and writing about the DNG format since it was introduced. They’re an excellent resources so I’ve added links/summaries to his posts below.

DNG Part 1 – Seven years of writing about Digital Negative Format
This article provides the background on all of the material Barry has written on the DNG format

DNG Part 2 – Timeline for the Digital Negative Format
The timeline of major DNG announcements is covered as well as this interesting tidbit:

“During the first 5 years when about 38 camera models were launched that wrote DNG, Adobe software added support for about 21 Canon models, about 20 Nikon models, and about 22 Olympus models. Camera models that write DNG are almost certainly launched at a much higher rate than camera models that support any other individual raw image format, including NEF, CR2, and ORF.”

DNG Part 3 – The tragedy of OpenRAW
The story of the OpenRAW initiative

DNG Part 4 – DNG is the ONLY archival raw file format
Barry outlines the value of the DNG format

I’d like to thank Barry for putting these articles together, summarizing his tireless efforts over the years to document and chronicle the progress of DNG.

How to optimize Lightroom performance

Anita Dennis, Learning Resources Senior Content and Community Lead, recently published a new support document, “Optimize performance | Lightroom” in response to a suggestion over at feedback.photoshop.com.

“Optimize performance | Lightroom” explores hardware configurations, Lightroom catalog and preview settings, and system maintenance tasks that can help Lightroom run at peak efficiently. Check it out and give us your feedback. Answer the question, “Was this helpful,” at the top of the article and share comments on how we can improve the content.

Thanks to customer Chris Niestepski for starting the discussion and prompting us to create the doc.

Lightroom 3.4.1 and Camera Raw 6.4.1 now available

Lightroom 3.4.1 and Camera Raw 6.4.1 are now available on Adobe.com and through the update mechanisms available in Photoshop CS5 and Lightroom 3.  This update addresses an issue introduced in the Lightroom 3.4 and Camera Raw 6.4 release where, in very rare cases, JPEG files could become corrupted after editing the metadata in the file. This update also corrected another rare issue that could cause valid JPEG files to appear with incorrect color.

 

Potential JPEG Bug in Lightroom 3.4 and Camera Raw 6.4

The Lightroom and Camera Raw team would like to inform you of a potentially severe bug that was introduced in the Lightroom 3.4 and Camera Raw 6.4 update.  Please note that this bug only impacts customers who are saving metadata to JPEG files with a rare characteristic.(JPEG files must have an unusually large block of private camera data included in the file to be susceptible to the bug*)   This scenario is so rare that we do not believe that it is necessary for customers who have already upgraded to revert to the previous version of Lightroom or Camera Raw.  However, the bug could cause image corruption which falls within our highest severity category of bugs.  The team believes it’s very important to notify you of the risk and provide an estimate of when we will be able to deliver a correction in the form of Lightroom 3.4.1 and Camera Raw 6.4.1.  We intend to have these updates available by Friday, May 27th.

If you do work with a significant number of JPEG files in Lightroom or Camera Raw and routinely update metadata(keywords, captions, etc) it would be prudent to wait for the updated release of Lightroom and Camera Raw.

The team would also like to thank Doug Cooper who reported this issue on the Lightroom Feedback Portal.  Rare bugs like this make it quite difficult to pinpoint the source of the problem or even create a reproducible scenario but thanks to Doug’s persistence we were able to track down this bug quickly.

*To date we’ve only found one camera that generates these large blocks of private data, the HP PhotoSmart R607.

DNG Converter 6.4 last to support PowerPC Mac Systems

The Camera Raw team recently provided a release candidate of the Camera Raw 6.4 plug-in and the DNG Converter 6.4 application. For those not familiar with the DNG Converter it’s a free, standalone application that is able to convert over 300 proprietary raw formats to the openly documented DNG file format.  When a new proprietary raw file format is released, essentially every new camera model with raw capability, we need to update the DNG Converter so that it’s able to convert that proprietary format to the DNG format.

The PowerPC(PPC) Mac systems, commonly referred to as G4 or G5 systems, represent a significantly different platform than the Intel-based solutions Apple started offering in January of 2006.  Due to the differences in software development environments, Photoshop CS5 and Lightroom 3 both dropped support for PowerPC systems in 2010.  However, we’ve extended PowerPC support for the DNG Converter into 2011 in order to ensure that customers who are still utilizing PowerPC Macs and are unable to upgrade to the latest version of Photoshop and Lightroom would be able to read raw files from the most recent camera models by converting the proprietary file to DNG and opening the DNG file in a previous version of Photoshop or Lightroom.  However, there is increasing overhead required to support the PowerPC code base in the DNG Converter so the final DNG Converter 6.4 update will be the last update to support PowerPC systems.

[Side Note: It’s come to my attention that many comments have been getting trapped in the Lightroom Journal’s spam filter.  I’ll be watching more closely to make sure that your comments are published. -TH]

    • Full screen performance issues have been addressed

    George Jardine publishes new Lightroom 3 Tutorials

    Adobe’s former Lightroom evangelist, George Jardine, has published a collection of video tutorials for Lightroom 3. This series focuses primarily on organizational and file management workflows in Lightroom’s import dialog and Library module. George also created an incredible series of Lightroom podcasts with industry influencers that are definitely worth a listen if you didn’t catch them when they were first released.

    Lightroom 2.7 and Camera Raw 5.7 Now Available

    Lightroom 2.7 and Camera Raw 5.7 are now available as final releases on Adobe.com and through the update mechanisms available in Photoshop CS4 and Lightroom 2. These updates include camera support for the following models:

    • Canon EOS 550D (Digital Rebel T2i/ EOS Kiss X4 Digital)
    • Kodak Z981
    • Leaf Aptus-II 8
    • Leaf Aptus-II 10R
    • Mamiya DM40
    • Olympus E-PL1
    • Panasonic G2
    • Panasonic G10
    • Sony A450

    Release Notes:

    • Camera Raw 5.7 includes an updated demosaic algorithm
      designed to provide compatibility with settings applied in Lightroom 3 beta 2.
    • Lightroom 2.7 also includes the same updated demosaic algorithm. The updated demosaic algorithm will appear as a subtle shift in noise characteristics at default values.
    • By default Camera Raw will display the image adjustments
      exactly as performed in the Lightroom 3 beta 2 develop module.  However, at this time Camera Raw 5.7 is
      unable to support further adjustments to the following settings or tools:
      • Highlight Priority and Color Priority post-crop vignette
      • Enhanced Luminance and Color Noise Reduction
      • Grain effects
      • Process Version

    Thank you to everyone who provided feedback on our Camera Raw 5.7 and Lightroom 2.7 Release Candidates.

    Update for Leica M9 Customers

    The Lightroom 2.6 update included a bug that could cause Lightroom to crash unexpectedly when encountering certain raw files from the Leica M9 camera. This bug is an unfortunate consequence of attempting to tune our raw processing algorithms specifically for the M9 camera based on feedback on our Lightroom 2.6 Release Candidate. Due to the severity of this bug, we have released Lightroom 2.6.1 with a correction for the issue. This update is only applicable to photographers working with files from a Leica M9 camera.

    Lightroom 2.6.1 : Mac, Windows

    Thanks for your patience while we resolved this problem.
