If you're running a Mac and haven't upgraded to Photoshop CS4 yet, then I have good news for you. You can get the latest version of Adobe Camera Raw (5.5) with all the current profiles, and the CS4 version of Bridge, with the just-announced Photoshop Elements 8 for the Mac, and you can get it for $79. (According to the official press release, "Adobe Photoshop Elements 8 for Mac will be available in Oct. 2009." You can have Adobe notify you when it's available.) As part of the deal, you get Adobe's latest merge technologies included the new Photomerge Exposure.
One of the reasons I think this is exciting is because the Bridge CS4/ACR workflow is so powerful. If you really look at what's there, you only need Photoshop or Photoshop Elements for the finishing touches on your best photos. I wrote an entire book on this approach.
You can hear all about it in my interview with Bob Gager podcast. Bob is the Elements product manager for Adobe.
