Well, if you expanded the picture, you could make out some details.. In any case, it was intended to give an impression of the Night Safari's (dark) atmosphere.
No offense but they are loads more crappy pictures on the forum to take cheap shots at (eg. a dozen shots of the same exact animal moving about a quarter inch between shots)
While not to be considered great photographs due to the difficulty in taking under such conditions, I for one, feel these pictures to be valuable in presenting the look and feel of Night Safari. Thanks Zooish.
