When I was doing my club shoots, I often do not go faster than 1/3s of shutter speed. Partially it was due to hardware limitation and secondly is because I love the effect of a long exposure. Long exposure gives a creamy light effect when used under the correct condition.I had a very ancient hardware. Something that I do not mind dropping, and spilled with alcohol. It was a rugged camera that does its job. In an exchange with that, ISO noise is abundance, which is why I often stay below ISO400.
ISO400, f/3.2, 1/3s, SpeedLight at 1/32
