Your thread is important, especially when you read - a few of my past concerns included - all of the threads about underexposure and the like. Then in response, you hear threads from others who say, "what's the fuss," 'cause theirs are working perfectly. Of course that becomes frustrating to the max.
I have always suspected across-the-board quality control problems that resulted in D100's being shipped that were not calibrated correctly - if that is the correct term. Although I also use NC-3 and have uploaded a wonderful curve posted on the DP Review web site - the Apolinario curve - I also elected to purchase the Fuji S2 Pro which has shocked me at the wonderful photos given me right out of the camera without post processing. I won't go down that road because it would only elicit varying comments.
For those of you who are interested, the Apolinario curve and particular thread link are listed below. The curve is free for download and has been downloaded by many Nikon d100 users around the globe.
