The first photo is taken using the best exposure possible to get the greatest amount of information. The sky is too bright and the objects are too dark but it's a good compromise.

The second is taken with a shorter exposure. The sky is great but you can't see any boats or land.

And the final image is taken with a longer exposure, capturing the boats really well but the sky is blown out.

Combining the photos together and conducting some 'tone mapping' with Photomatix and this is what you get. Pretty cool for a first go.

And another one.

Once I pay for the key I'll be able to get rid of the watermarks created by the trial version. Happy days.
