With And Without


Today's lesson: The polarizing filter. Take a look at the shot above and compare it to the one below. I took these two pictures today about 5 minutes apart. The one above was through a polarizing filter, the one below without the filter. You can see the shot above has bluer skies and deeper green water. You can also see items in the water that are obscured by reflections in the shot below. That's what the filter filters, reflection. Now you know. What you're looking at, by the way, is a sand dredge. It's removing sand from the bottom of the canal at the north end of Anna Maria Island, and pumping it up onto the beach a few hundred yards away.
