Hi there,
Ever since I bought the Canon SD600 camera, I became picture taking frenzy person. This camera has a "Digital Macro" shot feature which makes it easier and nicer to take pictures of the aquarium compare to the other camera I used to have (Sony DSC-P72). However, as you can see that the quality is still not as good compare to the better and more expensive models along with the high quality macro lens (my wife decided on this camera because of the pocket-size and because it is easier to take pictures of our kids). Anyway, please enjoy the Tiger shrimps pictures.
