I know it's a good photo when my heart asks me to keep this moment. Then it's a matter of looking through the viewfinder and press the button. Here are some quotes that describe what photography means to me.
“You don't make a photograph just with a camera. You bring to the act of photography all the pictures you have seen, the books you have read, the music you have heard, the people you have loved.” Ansel Adams
“A great photograph is one that fully expresses what one feels, in the deepest sense, about what is being photographed.” Ansel Adams
