Looking at the way photographers photograph moving water is quite interesting. In order to give the impression of rapid, gushing motion, the exposure should be longer and so, rather than photographing in #AutomaticMode, it is better to use #ShutterPriority and adjust #ShutterSpeed to achieve the desired effect.

Here the shutter speed in automatic mode is 1/100 s.

And here is the same in shutter priority mode with a speed of 1/15 s, which makes the water look that much more dynamic.

A #terrestrial demonstration of why it's just about impossible to see the #Moon's surface and #stars simultaneously. Tonight the Moon and #Jupiter (a wandering star or #planet) are in #conjunction -- well just about. And here are two images taken with two different #exposure time.

The first is with a #ShutterSpeed of 1/6 s. The lit part of the Moon is a white featureless blob but, because it's a #misty #night, there's a wonderful #ice #halo which shows #colours from the #VisibleSpectrum. You can see Jupiter directly above.

Next, with a shutter speed of 1/100 s, the #surface of the Moon shows much more contrast but you can barely see Jupiter. Also, the #fog is also invisible.
