This is more of a heads up to interested parties. Adobe has released a free public beta of a new product called Lightroom. It's focus is image management and processsing. At this moment, the software is only available for PowerPC-based Mac's running OS X. However, in the near future it appears that Adobe will release free public beta's for the new Intel-based Mac's as well as MS Windows-based computers. There is a pretty good article describing the software's current capabilities here
and a page on Adobe's website (really Macromedia's) describing the product
If you just want the executive summary, this looks to be a more capable and well thought out product than Apple's Aperture, with Adobe Camera Raw and a fair amount of Adobe Photoshop integrated in as well.
It appears to me that Adobe is releasing this to get it out into the digital photo community and get constructive criticism and feedback. They actually want to hear from the user community so that they can incorporate changes before the final release ships later this year. The software IS beta, it does have some shortcomings and limitations (see the first link I posted), but it's free until the final version ships, so it doesn't cost you anything to try it.
So if there are any adventurous PowerPC-based Mac owners out there, you can grab a copy from the second link I posted. Enjoy.
PS, I don't work for, nor am I affiliated with, Adobe. I have yet to take my own advice and download it. But I do intend to put it through it paces and see for myself what it can do.
