Why use iPhoto instead of manually saving images?

Solution 1:

Most things you can do in iPhoto you can do in Preview and Finder, except a lot slower. Organization in iPhoto is more powerful than simply using a file system.

• You can sort:
  • by Event
  • by Location
  • by Person via facial recognition
• Arrange into albums (Unlike folders, photos can reside within multiple albums.)
• Shows extra metadata, such as:
  • Stars
  • Camera and settings used
  • Map position
• Allows basic image touch ups:
  • Color-grading
  • Auto touchup (really hand, fast and convenient)
  • Built in "straighten" function (also very useful)
  • Auto-enhance
  • Automatically retains "originals" in case you want to revert an edit
• Manages Facebook and Flickr albums
