Occasionally, a friend or family member will ask how these cameras I use work. Invariably, they fathom the simple things, like bigger lens opening lets in more light, faster shutter speed tends to freeze movement, etc. But, as soon as I start talking about anything more specific -- setting aperture, depth of field (how did you make the background all fuzzy?), and all that -- eyes glaze over and they nod off. Explaining an f-stop is painful. 🙂
These are the people who need cameras that do everything but make toast. And more power to them.
