This may seem strange to imagine, but there was a time when you could only take photos with the iPhone's camera and nothing more. You couldn't take video, you couldn't use filters or Portrait Mode — it was a simple point-and-shoot affair. Nowadays, you can do so much on an iPhone, that accessory makers have come to the aid, to enhance how you take photos and videos.
Moment is a great example of this, where they offer a bunch of cases and lenses that attach to an iPhone. When you combine this with the Camera app, you can take some photos and videos in ways you wouldn't be able to without these lenses.
