Shallow Depth of Field

Sometimes I get questioned as to why I would spend so much more for a lens with a faster (smaller) f-stop. The answer is creative focus control.  If you want a certain image to just pop or draw the viewers attention to a specific area of the image, try using a smaller f-stop.  Sometimes you want the whole image to be seen in focus, but you run the risk of creating a snapshot and not a possible piece of art; make that decision before you click and you will be much happier with your photography.
