Day 93: Flow rate

After realising that there would be no sign of colour to this morning’s sunrise, I headed over to the local weir.
I find water very relaxing to watch. The different speeds that it moves over little areas within a stream can lend themselves rather well to photography. Whenever I’m shooting moving water, I try to be conscious of this, and aim for a shutter speed that accentuates these differences, freezing movement in some of the flow whilst blurring others out entirely.
As these characteristics can change very suddenly, you can’t plan for your composition in advance if your aim is to photograph the details. It’s also a subject which can benefit from a slower lens, as you are more likely to hit the “sweet spot” when you match the aperture against your chosen shutter speed for the correct exposure. Zoom lenses like the Tamron 18-270mm PZD then are excellent for this sort of thing. Changing lenses near water can be risky (and that’s coming from someone who tried to release a fisheye into the wild once), so it’s a huge advantage if you don’t have to.

Above the weir, and a completely different mood. A discarded tyre resembling some aquatic beast.
