Adobe has released the Windows version of Lightroom Beta 3, its new program aimed at professional photographers, the same market targeted by Apple's Aperture. The beta for Mac OS X has been available for awhile, and both versions can be downloaded for free from Adobe's web site (though its servers seem a bit overwhelmed just now). The Lightroom web site has some videos that show just what can be accomplished with the program.

[Thanks, Mr. Kaiser!]
