Hi Mike,
Thank you for your comments.
I'm used a Canon 450D with a EF-S18-55mm IS, set at 18mm. Yeah the
first two do look a bit too over exposed. That has more to do with my
experience, and the process I took. Maybe in these situations I need to
set the exposure on the sky and horizon and then recompose to include
the shoreline.
Thanks for looking.
Cheers,CS
