These water reflections were photographed 3 times, each with a different shutter speed (exposure). The 3 images were then blended together using a technique known as high dynamic range or HDR for short. I have a short HDR tutorial over at SLR Photography Guide, for anyone who is interested in this type of imagery. It's a little too long to explain here.
The photographs were taken at Mackay Botanical Gardens, QLD Australia.
