Lightroom Journal Blog Entry:
Important Lightroom 1.4 and Camera Raw 4.4 Update
The Lightroom 1.4 update for Mac and Windows has been temporarily removed from
the Adobe.com web site. Those Lightroom users who have installed Lightroom 1.4
should uninstall the update and install Lightroom 1.3.1.(Mac, Win) until a
further update can be provided. For those not in immediate need of the updated
camera support available in Camera Raw 4.4 or the DNG 4.4 Converter, it’s
recommended that you also continue working with the 4.3.1 versions. (Mac, Win)
This decision is based on the following errors that have been discovered with
the recent update:
* EXIF Time Stamp Error: There is an error in the EXIF time stamp update
technology that causes Lightroom to believe that the files are out of sync with
the correct time stamp as displayed in Lightroom. Any ensuing metadata update
will attempt to incorrectly modify the EXIF time stamp in the original raw file
itself. This is the only metadata field that Lightroom will write to an original
proprietary raw file. This error will not impact the integrity of your image
data. The Camera Raw plug-in also will incorrectly change the EXIF time stamp in
files converted by the plug-in. The information written to the XMP sidecar files
or XMP metadata in the converted files will remain correct.
* DNG Conversion Error(Windows Only): With the latest version of the Lightroom
1.4 and Camera Raw 4.4 applications, Adobe has included technology to verify
that the image data in a DNG file is unchanged from when it was originally
converted to DNG. Unfortunately, when converting to DNG using Lightroom 1.4 on
Windows, the application will write an incorrect verification tag to describe
the image data. When Lightroom attempts to work with those files in the Develop
module, the application reads that incorrect tag, believes that there is
something wrong with the raw data and will present an error. Rest assured, there
is nothing wrong with the integrity of your image data or metadata. For those
that have already converted their files to DNG using Lightroom 1.4(Windows only)
we recommend using the DNG 4.3.1 converter to convert the DNG files you’ve
created with Lightroom 1.4.
* Olympus Conversion Error: There is an error in converting Olympus JPEG files
to other formats in Lightroom 1.4 and the Camera Raw 4.4 plug-in.
To uninstall Lightroom 1.4 please see the instructions per your platform:
Mac: Delete the Lightroom application in the Application folder(Mac) and Delete
the following file: Library/Receipts/Adobe Photoshop Lightroom.pkg
Windows: Choose the Uninstall Lightroom 1.4 menu item from the Windows start
menu. The Add/Remove Program utility on Windows will also achieve the same
result.
To replace the Camera Raw 4.4 plug-in with the 4.3.1 plug-in, follow the manual
installation instructions provided on the download page linked above.
I will post additional updates to this blog as we have more information on the
timing and scope of the future update.
