Adobe says updates to Photoshop Lightroom and the Photoshop Camera Raw plug-in are now available immediately as free upgrades for existing users. Both updates are available immediately for download from Adobe.com or via the Adobe Update Manager by clicking on Help -> Updates from within Lightroom or Photoshop.
The new versions provide added raw file support for nine additional digital cameras, including the Canon EOS 450D, Pentax K20D and Nikon D60. Lightroom 1.4 also provides updated printer driver compatibility for Apple Leopard Mac OS X 10.5.
Lightroom 1.4 and Camera Raw 4.4 also include corrections for the following issues:
â€¢ 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.
â€¢ 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.
