Light and Water: Post Four

So far, I've been sharing photos that show bodies of water appearing as mirrors and appearing like sheets, depending on the conditions.

On twitter and in blog comments, I've heard about a range of ideas:

• wind roughing the surface of the water
  
• minerals, sediments, glacial flour in water influencing the color
  
• angle of the sun and the viewer changing what gets reflected to viewer, and
  
• those same angles changing whether the light mostly reflects off the water or refracts into the water.
• Update: The influence of a polarizing filter
  

In this post, I show three photos taken from Ship Harbor in Acadia National Park. In the first photo, the water acts like a window, letting us see into the bottom. With the second photo, I take few steps, turn my head, and the water changes character dramatically. How would you explain the difference? What, if anything, does this have to do with the ideas above and the phenomena shown in post one, post two, and post three.





In this third photo, the water shows its many different faces in a single shot.
