Good collection, but in the first photo the top right corner seems to be bit over exposed....
As Adi has said, first two got my attention... BTW did you use any filters for those water shots?
No filters - these were all taken with my Canon G10.
Yes the sky is burnt out on the first shot but not sure how to get around that without lots of messing around in Photoshop. I don't like messing with photos with software - it feels like cheating, and anyway I'd rather be out there taking photographs than inside processing them on a computer. Guess that's why I shoot mainly JPEGs.
