Smoking Cloak 1 and Smoking Cloak 2.
These two pics come as a pair for one simple reason; they both appear to show the same formation. Now it is true that owners of the property that these pics were taken in are smokers, so the pictures could just be smoke. Take a look at the shape of the smoke though, in both pictures a hood seems to be forming out of the smoke. Now these pictures were taken approx six weeks apart so it can't just be that the formation has moved between shots. If you look at the clock however you can see that they were taken around the same time. Maybe some experimentation is needed here. Both pics taken with a digital camera (Olympus c-100 1.3 mega pixels)
