i say rough because there were two different photographers. also, mine was not under the best circumstances -- i was shooting JPEG and not particularly balanced well. the image could easily have been shot better on the GRDII than i did (those who have one, know what i mean). it was a quick turnaround and crouch in a puddle to get the moment. the DP1 one was obviously painstakingly taken.
still, i think it kind of exemplifies how much more you can get from the larger DP1 sensor and lens in some situations. this is where it excels! (all that said, i still like mine better)
