My long, 180mm, lens was actually in my bag getting ready for Connemara, and I took it out (looking for ways to save a little weight). I knew at the time I would regret it. I did regret it. So as soon as I was back, I took it out in the backyard and gave it some exercise.
Of course, I’ve always known that you can use a polarizer to darken the sky. When you are at right angles to the sun. And I knew something of how they could reduce reflections, as in windows or ponds. But I had never taken that to heart and thought »
