Attach an accessory
For true photography aficionados, there are dozens of external lenses on the market that can significantly improve photo quality, like olloclip or Moment, which essentially transform your phone into a proper DSLR.
Play around with panoramas
No matter how well you're composing a shot, sometimes you simply can't convey the sheer scope of something without an extra-wide shot, and the Pano mode makes it incredibly easy to capture just that. When you move the phone slowly in one direction in Pano mode, the camera automatically stitches together a striking panoramic view of up to 240 degrees.
