They can be great, like any other "genre" shot, if done well. The images above by LynnB blow me away. Those seagulls? Holy Cow! Just terrific stuff. Poorly done they are as boring as any other technical fail.
One of the things I like best about photography is the ability it gives us to show the world beyond the limits of our ordinary sensory capabilities. Long exposures, really short exposures, panoramics that take in more than the sweep of a normal set of eyes, macro photography, tele photography, time lapse photography, pinhole photogrpahy . . . each of these can show us more of the world than we can see in a fleeting glance. Having said this, not many of us are as good as a Sugimoto . . .
