Going from Lightroom 1.0 to 1.1 was a major upgrade, with considerable changes to both features and performance. Last week Adobe announced Lightroom 1.2 and while there are no new features, there have been some under the hood changes that you should be aware of.

First, Lightroom (along with the newly released Adobe Camera Raw 4.2) now supports 14 new digital camera RAW formats, which means support for the Canon EOS 40D, Fuji FinePix IS-1; Leaf Aptus 17, 54s and 75s; Olympus EVOLT E-510; Panasonic DMC-FZ18; Pentax K100D Super; Phase One P 20+, P 21+, P 25+, P 30+ and P 45+; and Sony A700. There have been some under the hood tweaks as well. For example, the Develop module’s noise reduction default setting for Bayer patterned sensors has been scaled back to allow for more image detail at that setting. Seems that some photographers were complaining that the default setting was too strong, hence the change. Also, Lightroom Window users should no longer experience Vista grid display errors. And finally, Adobe claims XMP auto-write performance has also been improved for both the Mac and Windows platforms. (I haven’t tested this so I can’t confirm.)

Registered users of Lightroom can upgrade to 1.2 for free at www. adobe.com

BTW, since the features of 1.2 are virtually identical to those of 1.1, users of my Photoshop Lightroom Adventure book are in good shape. Everything I wrote still applies.

I’d love to hear from anyone who has upgraded to 1.2. Any problems? Anything worth noting? There doesn’t seem to be much chatter out there, which I guess is understandable considering the “maintenance” nature of the upgrade.
