The following updates were included as part of the now withdrawn Lightroom 1.4 and Camera Raw 4.4:

* Previous camera profiles identified in the Calibrate panel of the Develop module may have displayed poor results at extreme ends of the temperature and tint ranges. A new camera profile identified as Camera Raw 4.4 is now available and will be applied by default to all images without existing Camera Raw or Lightroom settings. The creation of new default profiles will also include the updated Camera Raw 4.4 profile. Images edited in Camera Raw or Lightroom with earlier profiles will retain the earlier profile value and visual appearance.

* In previous grayscale conversions the Color Noise setting was disabled and this could result in an image with excessive noise when grayscale channel mixing is applied. Both the tool and effect have been enabled in Lightroom 1.4 and Camera Raw 4.4 providing the ability to reduce noise in grayscale conversions. In order to return to the prior visual appearance, Color Noise reduction can be set to zero.

The corrections to the previous version are detailed on Adobe's 'Lightroom Journal' blog:

Lightroom

* Lightroom 1.4 incorrectly modified the EXIF time date field of images that had a metadata update applied. This incorrect modification does not appear in Lightroom or Bridge and is only viewable through third party EXIF tools. This error has been corrected in Lightroom 1.4.1 and all files in a Lightroom catalog that have been incorrectly modified will be corrected on their next metadata update. (Metadata can be updated by selecting the files in the Library grid view and choosing Command or CTRL + S to save and update the metadata.)

* Olympus JPEG files could render incorrectly in Lightroom 1.4, displaying an artifact in the exported file.

* Any conversion to DNG in Lightroom 1.4 (Windows Only) would cause the DNG file to become unreadable by Lightroom’s Develop Module or Camera Raw 4.4 in Photoshop. The issue has been corrected and files can be converted to DNG again in order to resolve the issue for existing files. Returning to the original native raw files is not necessary. The affected DNG files can be selected and converted again using the DNG Converter 4.4.1 available at www.adobe.com/dng/. This process is not required but recommended to ensure that a correct validation value is stored within the DNG files.

* Lightroom 1.4 provided degraded import performance relative to Lightroom 1.3.

Camera Raw

* Camera Raw 4.4 incorrectly modified the EXIF time date field of images that were saved as TIFF or JPEG files from the Camera Raw dialog. This has been corrected in Camera Raw 4.4.1

* Olympus JPEG files could render incorrectly in Camera Raw 4.4, displaying an artifact in the exported file.

OSX 10.5 compatibility

● Lightroom 1.1 catalogs with user-specified sort order could not be imported into another catalog
● Lightroom 1.1 for Windows could at times display gray boxes instead of image thumbnails
● The preference to write XMP metadata automatically in Lightroom 1.1 could attempt to write metadata indefinitely for
offline images causing significant performance problems
● Images could be dropped from the Quick Collection upon reordering of the source folder
● Catalogs could not be exported to drives smaller than 250MB
● The Web Module was not accessible in Lightroom 1.1 on the Macintosh platform when Lightroom was installed on
case-sensitive volumes such as the Case Sensitive HFS+ (Journaled) volume
● Errors occurred exporting to a Linux SMB network volume
● Scroll position in the grid view was not maintained when changing the view option using the J shortcut key
● The tokens for image number and image count were not displaying properly in the Slideshow module
● The metadata panel could display incorrectly on Windows
● Slideshows on the Macintosh platform did not display properly when a 256MB ATI graphics card was connected to 30
" LCD
● The Lightroom 1.1 Web module export did not position the copyright tag in the same location displayed in the preview
● The auto-eject functionality on Windows ejected the card reader device in addition to the card
● Noise reduction adjustment for all cameras with Bayer Pattern sensor: The base point noise reduction applied at the
demosaic stage of raw processing has been reduced. The resulting effect is that images with zero luminance noise
reduction applied in Lightroom 1.2 will contain more noise than the identical settings in Lightroom 1.1 but less noise
than identical settings in Lightroom 1.0.
● 1:1 previews were not discarded according to the timing set in the Lightroom preferences
1:1 previews are not built for an entire set of images when requested after import
