Adobe updates Photoshop Lightroom, Camera Raw, DNG specification

Adobe has released the final Photoshop Lightroom 2.4 and Camera Raw
5.4 updates, available for immediate download at
http://www.adobe.com/downloads/updates/

Both updates bring additional raw file support to 31 camera and
camera back models including the Canon EOS 500D, Nikon D5000 and 18
Hasselblad models. In addition, Adobe released an update to its
Digital Negative specification (DNG), the public archival format for
digital camera raw data. DNG addresses the lack of an open standard
for raw files created by individual camera models, helping to ensure
that photographers will be able to access their files in the future.

DNG 1.3 now includes opcodes, a defined list of operations and their
parameters for performing complex activities in the raw file
conversion process. These activities include corrections and
enhancements that are beneficial when performed prior to the demosaic
process but are difficult due to a camera’s limited processing power.

They also include corrections and enhancements that can only be
performed after the demosaic process such as lens correction. By
utilizing opcodes, photographers can maintain the advantages of raw
mosaic data, giving them increased opportunity to improve their
photographs with the maximum amount of image data preserved. The DNG
SDK has also been updated to reflect the changes to the specification.

The Adobe Photoshop Lightroom 2.4 update is available as a free
download for existing Lightroom 2 customers and Camera Raw 5.4 is
available as a free download for existing customers of Photoshop CS4,
Photoshop Elements 7, Premiere Elements 7 and Photoshop Elements 6
for Mac.
