Usind Mac G5, already had Aperture. Got a D200 so I needed a RAW solution. Noticed a post about Bibble, downloaded it to try. In the process of connecting the D200 Aperture opened automatically, I set a folder hoping it might work. Of course the pics could not be viewed. Used Bibble, pics were viewable (though certainly not all were keepers). Later in the evening after trying to figure out how to save the images using Bibble, etc. I stumbled on to the fact that Aperture had downloaded them into a directory and they were viewable in Bibble. Weird thing is that after viewing them in Bibble when I went back to Aperture they showed there also, until I tried to do something with them. Then of course, Unsupported File or some such. :-( I sure hope that when Apple updates Aperture for the D200 it will then work with these images okay.
