There are always some photos that just don't fit in to any particular sub-category, such as this unusual entry from regular entrant and previous prize winner, the very talented Csaba Meszaros of Leamington Spa, UK. I'll let Csaba explain: "A couple of shots were made with the Minolta AF 8/500mm mirror lens and put together in panoramic format. I removed the warm colour cast of the Sun to make the blue of the water dominant."
Another semi-abstract shot is this excellent high-key composition from David McSween of Hartlepool, UK. David used his Konica Minolta A200 super-zoom camera with the lens at its 28mm wide-angle setting, and an exposure of f/2.8 at 1/60th of a second. I assume he's tweaked the saturation and contrast in Photoshop.
A good antidote to all the duck pictures is this great photo of a Caiman from Drew Winters of Abiline, Texas. I love Caimans; they always look like they've just done something evil and got away with it. Drew took this on his brand new Canon EOS 50D on the day he bought it, so hopefully it's the first of many great shots. Exposure was 1/50th of a second at f/2.8.
