Sometimes, it really does help to be composing in a particular format.
My panasonic LX3 has a “16×9” mode that gives me this panoramic look. Even though I know I can take the regular, full frame and crop it, looking at the screen while in 16×9 makes you see things differently, I think.
In this case, I could feel the symmetry of the mountains on either side with the boat in the middle much better, I think, than if I had a much more square frame and just tried to visualize.
