Adobe has updated Adobe Camera Raw to version 4.2, and Lightroom to version 1.2.

They add a bunch of new digital SLRs file formats to their list of supported RAW files, including the Canon 40D, the Olympus E-510, the Pentax K100D Super, and the Sony Alpha A700. However, the Canon EOS 1D Mark III’s sRAW format is not supported yet.

There’s also an interesting note about a change in the noise reduction defaults for cameras with Bayer pattern sensors, which would be almost all of them. They write:

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 Camera Raw 4.2 will contain more noise than the identical settings in Camera Raw 4.1 but less noise than identical settings in Camera Raw 4.0.

Does anyone have some sweet comparison samples available yet for all of us to pixel peep at? Give me your links in the comments section.
