I have a D90 with th 18-55mm kit lens and shoot in RAW on the largest and best quality. I have taken several landscapes photos as well as photos of buildings etc. They have never, to me, seemed to hold as much clarity as I have seen on other photos taken with D90s. I shoot on either the aperture or shutter speed settings, I usually select the an aperture of about f13, and always use a tripod, VR is on. I may have to post up some examples of my shots. Any help would be extremely grateful.
