Look up. It’s a simple, perhaps absurdly simple, piece of advice for photographers, but the best advice often comes in the simplest packages.

If you’re lacking inspiration or haven’t captured something you really love in a while—walking the same streets, capturing the same scenes, and feeling like that creative spark is fading—try simply… looking up.

The 15 photos below—part of a wonderful gallery by photographer, 500px ISO contributor, and lover of all things photography Mark Cornick—highlight the amazing things you can capture when you follow this simple piece of advice:
