Lightroom 2.4 Bug Fixes

The Lightroom 2.4 update includes several bug fixes.  The following is a list of items FIXED in this release.

• Web galleries with a Collection Title of six characters would not export or upload
• The crop aspect ratio could revert to the last selected ratio even when reset to original
• The crop aspect ratio in Quick Develop could be lost after a crop adjustment
• The crop aspect ratio lock could be lost after an orientation switch
• Images could preview incorrectly when imported using the MTP/PTP USB protocol
• Sony .ARW files may not have been recognized by Lightroom’s import dialog
• The Japanese language configuration of Lightroom on Mac OS X 10.5 could fail to switch to the print module if the HP B9180 was set as the default printer
• Metadata options that are intended for use were dimmed incorrectly when exporting DNG files
• The Japanese language configuration of Lightroom on Mac OS X was missing a shortcut for “Zoom Out”
• Several translation and shortcut corrections were made for the eight additional languages introduced with Lightroom 2.3

New Lightroom 2.4 and Camera Raw 5.4 DNG Options

This release includes new DNG Compatibility conversion options. These choices help address the additional options available with the new DNG 1.3 Specification (http://www.adobe.com/dng):

• Camera Raw 2.4 and later: The DNG file will be readable by Camera Raw 2.4 (Photoshop CS) and later, and Lightroom 1.0 and later
• Camera Raw 4.1 and later: The DNG file will be readable by Camera Raw 4.1 (Photoshop CS3) and later, and Lightroom 1.1 and later. The DNG file will often be readable by earlier versions, depending on the camera model
• Camera Raw 4.6 and later: The DNG file will be readable by Camera Raw 4.6 (Photoshop CS3) and later, and Lightroom 2.1 and later. The DNG file will often be readable by earlier versions, depending on the camera model
• Camera Raw 5.4 and later: The DNG file will be readable by Camera Raw 5.4 (Photoshop CS4) and later, and Lightroom 2.4 and later. The DNG file will often be readable by earlier versions, depending on the camera model
• Custom: (Not available in Lightroom 2.4)
  • Backward Version Option: DNG 1.1, DNG 1.3 (default 1.3)
  • Checkbox: Linear (demosaiced) (default unchecked)
  • Checkbox: Uncompressed (default unchecked)

DNG 1.3 Specification Update

The DNG specification has been updated to version 1.3.[LINK] The update includes the following changes:

• In Chapter 2, “DNG Format Overview”, the section on Defective Pixels has been updated
• The section on Opcode Lists has been added to Chapter 2, “DNG Format Overview”
• The CFALayout tag has been updated in Chapter 4, “DNG Tags”.
• Additional Tags for Version 1.3.0.0 were added to Chapter 4, “DNG Tags”
• Chapter 7, “Opcode List Processing” was added.
• “Appendix A: Compatibility with Previous Versions” was updated.

The additional “Opcode Lists” allow complex processing to be moved off the camera hardware, which can have limited processing power, and into the DNG reader, which is often running on more powerful hardware. This also allows processing steps to be specified, such as lens corrections, which ideally should be performed on the image data after it has been demosaiced, while still retaining the advantages of a raw mosaic data format.

Acabou de sair mais uma atualização da sério 2.x do Adobe Lightroom, vou reproduzir o texto do Lightroom Journal com o press release.

Lightroom 2.2 is now available on Adobe.com. (Mac, Win) The release includes new camera support for the following models:

Canon EOS 5D Mark II
Canon PowerShot G10
Panasonic DMC-G1**
Panasonic DMC-FX150**
Panasonic DMC-FZ28**
Panasonic DMC-LX3**
Leica D-LUX 4**
We’ve also fixed a few bugs that were introduced with the Lightroom 2.0 release:

Lightroom 2 Bugs – Fixed

Images rendered from the Slideshow export process produced a jagged effect on hard edges relative to the quality of normal JPEG export
Increased the number of characters allowed in Web gallery labels beyond 150 characters
Catalogs with hundreds of root (top level) folders caused very slow launch times
Drag and drop to move a subfolder to a different folder showed the incorrect photos in the grid
Print Sharpening produced edge artifacts in certain conditions
Density defaulted to 100 percent for initial stroke regardless of position of slider
The Adjustment brush created blocky, straight edges to brush strokes under certain conditions
Lightroom could become unresponsive when using the graduated filter under certain conditions
It was possible to lose the ability to edit an adjustment brush setting after applying a graduated filter with hidden pins
Turning auto-mask on produced a lag in Lightroom performance in when applying the adjustment brush
Print to JPEG functionality produced a low resolution image when printing photos with panorama aspect ratios
Extended characters in a folder name caused Edit in Photoshop functionality to fail
Smart collection did not respond to changes in custom metadata
Lightroom 2 Enhancements

Camera profiles are now available in the Calibration panel in the Develop module. These profiles are designed to provide different interpretations of raw capture.
**With the release of Camera Raw 5.2 (and upcoming Lightroom 2.2 release) there is an important exception in our DNG file handling for the Panasonic DMC LX3, Panasonic DMC FX150, Panasonic DMC FZ28, Panasonic DMC-G1 and Leica D-LUX 4. In this release the native, proprietary files from these cameras can only be converted to linear DNG files. A linear DNG file has gone through a demosaic process that converts a single mosaic layer of red, green and blue channel information into three distinct layers , one for each channel. The resulting linear DNG file is approximately three times the size of a mosaic DNG file or the original proprietary file format.

This exception is a temporary solution to ensure that Panasonic and Leica’s intended image rendering from their proprietary raw file format is applied to an image when converted DNG files are viewed in third party software titles. The same image rendering process is applied automatically in Camera Raw 5.2 and in Lightroom 2.2 when viewing the original proprietary raw file format.

In a future release Adobe plans to update the DNG specification to include an option to embed metadata-based representations of the lens compensations in the DNG file, allowing a mosaic DNG conversion. In the interim Adobe recommends only converting these files to DNG to allow compatibility with third party raw converters, previous versions of the Camera Raw plug-in or previous versions of Lightroom.
