I've just been pondering a number of potential "Still Life" subjects for a forthcoming competition. I want something more interesting that a bowl of fruit.

Some of these involve a certain amount of smoke or fumes. For example, a candle which has just been extinguished and the residual plume of smoke is still rising from the wick (might look good against a black background).

The question is ..... does this qualify as "Still Life" ??? Or does the movement inherent in the smoke disqualify it? Any views on this?
