oldnick said:I had a D60 and now have a D3100. I found that both often over exposed on scenes that my basic compact would have no problems with.
Counter intuitively, under exposure is less of a problem at higher ISO settings. The basic message is, don't stick it on 100 ISO and assume that you are getting the best image quality.
I often shoot with -0.7 on the exposure compensation, this generally suits, also gives slightly faster shutter speeds and if needed can recover in photoshop as I shoot in raw
