The right exposure

This is not one of my best shots... meybe it can be considered one of my worst!
But I keep looking at it as it is one that has teached me something...

This shot has been made several minutes before the previous one... and it is the best of three or four try!!
The contrast in the image forced me to choose or a washed sky or silhouetted boats!

With the same lights only a couple of minutes later... I shot the photo from the previous post... and that has a good exposure... why? as I turned my back at the rising sun! (there's another thing I could have done as I'll show you in the next post).

P.s. I've already scheduled the next post before leaving...
