Adobe Lightroom Release Version 2.7

Adobe released Lightroom 2.7, Camera Raw and DNG Converter 5.7. According to Adobe version 2.6 was the final update to Lightroom 2.0. Adobe Lightroom 3.0 was going to be the next release but I guess they either miss calculated the release of Lightroom 3.0 or the need for bug fixes couldn’t wait.

Known Issues

• Burning exported images to disc is not available for the Lightroom 64-bit Windows application. • Upgrading a Lightroom 1 catalog during a catalog import can create multiple temporary copies of the
catalog while upgrading • Lightroom performance can be impacted when the Window’s Recycle Bin contains thousands of files • Lightroom may not automatically launch an import dialog when a memory card is attached to a Windows Vista computer. Please select the Import button in the Library and select the attached card reader to begin the import. • Lightroom 2.7 will not automatically migrate plug-ins located in the following directory: C:\Program
Files\Adobe\Adobe Photoshop Lightroom 2\Modules\. Any plug-ins in this folder should be moved to: o XP: C:/Documents and Settings/{your_username}/Application Data/Adobe/Lightroom/Modules/ o Vista: C:/Users/{your_username}/AppData/Roaming/Adobe/Lightroom/Modules/
Supported File Formats:
• JPEG
• TIFF (8 bit, 16 bit)
• PSD (8 bit, 16 bit)
• DNG • Proprietary raw formats (Please visit http://www.adobe.com/products/photoshop/cameraraw.html for afull list of raw file support. File support for Lightroom 2.7 aligns with Camera Raw 5.7)

New in Lightroom 2.7

The goal of this release is to address bugs that were introduced in previous releases of Lightroom 2 and provide additional camera raw support. A comprehensive list of issues fixed in this release is included below:

Lightroom 2.7 and Camera Raw 5.7 are now available as final releases on Adobe.comand 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

There’s more to this update than I saw at first. According to Lightroom product manager Tom Hogarty, Lightroom 2.7 and version 5.7 of the Photoshop plug-in adds Lightroom 3 beta 2’s new “demosaicing” technology for processing raw images.
Specifically, Hogarty said:
• 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; [and] Process Version.
