1/100, 1/500. f/4, f/5.6, which lens?  Which camera body? RAW?  JPEG? Sandisk? Canon?  Nikon? Etc.

When you start to get into photography you will be bombarded with choices.  The problem is, these choices (although important) are less important than you might think.  The camera is a brush.  The world is your canvas.  The dirty little secret to getting a photograph that will move you forever is to just be there.
