Thanks Michael and Nico. Michael, I tried to get a little movement in the water and yet keep the bubble sharp. I don't know if I succeeded. It does look like black oil but the water is actually crystal clear...despite the title ;^) -dtallakson
On second thoughts, maybe what I thought was out of focus is movement as a result of a slow shutter speed - as per the topic. Sorry if my first comment was off beam. Regards Michael
Somehow the ripples make me think of ripples in oil... thick, slow moving, sticky, dirty... don't really know why? Perhaps I am influenced by your title? That there is movement involved is without question and thus solidly on-topic, in my opinion. Compliments! Nico
