Harvey,
The tonalities of the last picture are wonderful. Water can be easily blown out in the highlights or undetailed and dark. You have a good exposure. I might suggest always sweeping the camera from more of the right to beyond the left, taking reserve overlapping pictures, even though you may not think you need it. Why?
I believe that today, the ideas we had in pure film days, were limited by the physicality of the film medium. We couldn’t easily overcome the fact that without a lot of effort, a composition was pretty well made at the time of pressing the shutter, except the telephoto lenses on the Leica rangefinder cameras, where the framing is not 100% predictable.
Here, however, the extra pictures cost zero and then at home, we can reassess our vision and have had time to dream a little more about the scene.
Perhaps no different framing decision will be made sitting in front of the monitor. Here, however, I'd wager that you could look at the marvelous colors and tonal range of that picture call for being extended in both directions.
When one has skies and water like that, we need to get as much documented for later work. I challenge the view that we MUST decide at the scene. Not now, not necessarily.
A scene like this is so impressive, we need to first save it, then afterwards just get lost inside it and relate it to all one's senses.
I love your choice of scenes.
Asher
