I figure this is the best place for this post. I just downloaded the free demo, and it works great in my blackbook. I am just starting to get into photography, and I'm not sure how to use the app. I am use to iphoto, and so far, aperture seems similar. Of course it has more options for manipulation. My question is how does it differ from photshop, and what benefits does it serve above what is offered in iphoto?
