Iphoto 11 Previews Folder. How come I have pictures in the Previews folder?

How come I have pictures in the Previews Folder when in fact I have not modified any pictures? It is also weird that when I view those pictures in Iphoto, the "revert to original" is lit and can be clicked. But when I do, nothing happens and remains lit. The other pictures that are not in the Previews folder do not have the "revert to original" lit and can not be click until I modified the picture, which makes sense.

Also, when using faces in the library, does Iphoto makes copies or duplicate your pictures or is it just a different view, kinda like how the album works when you create an album?

How do most of you guys sort your photos? For me, I have them on the Pictures folder. I then import only some folders to Iphoto, not all of them. And when I connect my digital camera, I do not use Iphoto to import the pics because I want a solid copy outside of Iphoto first. I don't know if that makes sense. I just got my macbook pro and Its my first time using a mac. Just want to know what others do. Thanks.

But maybe i found the solution: Importing the whole library to Aperture, keep modified and delete the masters, then re-import them back ti iPhoto and this way i'll have only masters.

So, explain again why you use iPhoto or Aperture? You want a destructive workflow but use - not one but two apps that work specifically against what you want? Why on earth would you do that? Why not just use Aperture?

I use iPhoto as just a library and Aperture for some corrections, b&w effects etc. I don't like using aperture for both, library and adjusting as it drains my ram while iPhoto doesn't. As soon as apple corrects ram using by Aperture, i'll switch to it. Another boring thing is that Aperture is english only, while i prefer using Italian.
