On the edge at Glacier Point

The moment one gazes upon this image, an overflowing of emotions arises.

It's iconic and powerful.  It's frightening and exhilarating.  It makes you sit with it and stare and most likely gasp a little.  The negative space helps ease the tension, but the overall composition quietly screams.

Carlos Luna, 27, made this photograph using his iPhone 6 on a weekend trip to one of his favorite places in California -- Yosemite -- a place he visits monthly.

Luna's friend, Sam, on his first trip to Yosemite, braved the edge for this photo made at Glacier Point. Luna first picked up a camera about a year and a half ago and says,  "I haven't been able to put it down ever since. I recently gave away my camera and now just shoot with my iPhone."  His Instagram feed is reflective of his love for the outdoors and documenting his journey.

I've seen countless photographs of Yosemite and the essence that Luna captured blew my mind. It's one that will stick with me for a long time -- I  physically wanted to move back from the picture.
