Water

vapour.  My first attempt at doing this kind of thing with limited resources.  I don't mind that the vapour is out of focus; I do mind that I couldn't be arsed to fiddle about some more to get the light on the vapour.  My thinking went something like this, "Water? how can that look interesting in monochrome?"  (How will we cope with air ?)  I could snap some clouds.  We had a few nice cumulus this morning.  Clouds are what?  Water vapour. So I boiled some water whilst I made my lunch and snapped away.
