You may want to remove the background in order to extract the subject — maybe you’re doing some kind of Photoshop trick, or making a greetings card.
Whatever your reasons, it’s easy to do. Removing the background from an image used to be a nightmare. Now, you just need the right app. And if you’re a regular with our Cult of Mac photo how-tos, you probably have that app already.
