The pen is an amazing instrument. With the pen you can write a grocery list, a poem, a novel, a letter, a memoir. The same idea applies to cameras. With a camera you can make a snapshot, a visual document, tell a story, or create a mood. But no one would praise a pen because you could use it to write a word, any more than using a camera to make a picture is its virtue. It's what gets communicated that makes these tools so valuable in their versatility.
