I've been using a Mac for a little over two years, and I've been happy with iPhoto, but there are quite a few things that I could do using Microsoft's various free photo editors that seem pretty basic to me that I miss and will occasional fire up Fusion to get into Windows and do. Namely, stitching together multiple photos to create a panorama, setting a portion of a picture transparent, overlaying photos, and manually creating a collage. All of which I don't think iPhoto does. Does Aperture do any of these? Is it simple to use? I honestly find Photoshop, on Windows, too much, and I like using the iPhoto database too, so it would be great if Aperture does what I want, instead of using a third party tool. Thanks in advance.
