In appreciation of precipitation

Let it snow!

There may be nothing better than water turning into strange forms for altering how we see the world around us. Rain, sleet, snow, hail... all of these change the place, and the day. Rain is a license to be late to wherever you're going. Sleet maybe not so much, that's just painful teasing. Hail, depending on diameter, is either absurd fun or death and destruction. There's something so magical about fog, in particular, if not ominous, then tantalizing with mystery and possibility. But snow may beat them all, at least for that first day, and then it turns dirty.

Metaphor for change?

Deep focus?

Deep focus is a photographic and cinematographic technique incorporating a large depth of field. Depth of field is the front-to-back range of focus in an image — that is, how much of it appears sharp and clear. Consequently, in deep focus the foreground, middle-ground and background are all in focus.
