Cataract below Mt Tamalpais, photo by Harold Davis. View this image larger.

There was a break today in the rainy weather that has hit the Bay area recently. I thought the waterfalls on the slopes of Mount Tamalpais would be running strongly, so I grabbed Julian and we hiked down to Cataract Falls. It was an adventure-filled journey, with wet crossings, a ranger to help to clear a blocked stream, and logs to clamber over. We had a great time, and it was good to get outside after days of cabin fever.

For this image of Cataract Falls, I bracketed shutter speeds, using a base exposure that was long enough to soften the water, and super-imposing a much shorter exposure that shows some of the frothy detail of the flowing water.
