The 3 biggest differences with iPhoto are:ġ) Aperture can import photo’s in it’s lib in a reference way. If you have a lot of photo’s it might be wise to get Aperture3. So you can always revert back to the original imported photo. All changes you make on the picture will be kept in a separte file. IPhoto will never change the original photo you imported.
Keep in mind that it is not really adviced to mess with this structure. Then you will notice it has a deep nested folder structure and you will find the photo’s in there somehow. You can see this if you go via the finder to the library and use the option to show the contents of it. Indeed iPhoto always stores photo’s managed in its library.
