Hmm - I don't see it at all. This monitor was calibrated many moons ago by a friend by I have had a laptop crash since then so I imagine it would not be valid. I have had one of the shots printed for my daughter at 8" x 12" and nothing noticeable but not sure if it was this exact image.
Thanks Roosta, lets see if anyone else notices banding.
@pmack, is there a way of testing for sensor banding issues, I regularly take a shot to check the status of dust on the sensor and not seen any irregularities there. I have seen a couple of threads where members have had banding issues on there 7D but the samples I seen were pretty obvious.
