As LRO orbits the Moon, it takes pictures of whatever is directly underneath it no matter what time of day it is locally. So it might be snapping images of the landscape at sunrise, or at sun set... or at high noon, as it did for this shot of the Apollo 16 landing site.
While the lack of shadows makes craters harder to see, it actually accentuates where the dust was disturbed by the astronauts' activities. The lander is obvious, and even the last parking spot of the lunar rover!
