This past weekend, Taipei was again overcast. For two days, the sky was totally gray. These were no ordinary overcast days. A weather front brought the sand storm from Mongolian highland of Nothern China to Taiwan within two days. There were not enough time for the rain to clean the air. The particles in the air were three times from previous highest record.
What to do on an overcast day, go take some photos of mountain stream. The dark sky allowed me to use slower shutter speed to record the waves. Both photos were taken using shutter speed at 2.5 seconds. I have to use mirror up function of the camera with a remote cord and tripod to keep the picture sharp. If you are someone like me of a certain age, carry certain amount of weight, use a telephoto lens and stay on the dry pavement. This river has taken many lives.
