It's been a while since we had a theme in the Group. Here's one for September/October in that case: Painting with time. Painting with light obviously involves using a lightsource as a 'brush' in which details are illuminated during a long exposure. Well, painting with time is that minus the 'brush'.
For those new to painting with time, a couple of pointers - Neutral density filters help a treat in lowering exposures. If you don't have one try a polariser, or even stacking polarisers (just don't cross them as you'll get a pure black image). The polariser will reduce the exposure by 2 stops. For once the lowest aperture also makes sense, even though it's soft, for the simple reason that if there's movement during the exposure it's going to blur in any case. The longer the exposure the more 'painting with time' there is.
Have fun with those long exposures!
