I'm going to take exception with SHONNER and urge 'no depth-of-field' [but definitely go with some haze]. I say this because we are so used to seeing depth blur in camera photos that we feel it's essential to our 2D renderings. But when I talk to a friend, I do not see things behind him as blurred. They may be so, [technically] because of the eye's construction, but the brain compensates. My world is always in focus...except when I take a photo of it.
