Exposure-wise, that is. These are not exactly identical as they were shot a few minutes apart and the light was changing frequently on a partly cloudy morning. The sun was peeking in and out between clouds which made for some interesting lighting along the shoreline of the Quabbin about a half hour after the dawn image I posted yesterday.
So there are two exposures here. The first was just with the polarizer and was 1/15 second.
The second was shot at 4 seconds with a 6 stop neutral density filter in front of the polarizer.
And, BTW, yet another repeat location. 🙂
