Thankfully, it did. The iPhoto app allows you to quickly edit photos with simple-to-use, but powerful tools. You can also apply Instagram-like filters. But the real draw is the organization. You can flag photos as favorites and create journals of specific events so you no longer have to scroll through your whole catalog to find a photo. Is it worth the $5? Yes.
