I've seen quite a bit of back and forth on it, and a interesting discussion this AM on AVS. Here is what I've experienced with my D7000: Lowering contrast below 90 results in 10pt controls acting strange. This can be overcome, but they don't respond as they should I've always kept Cell at 20, from my reading, but Im not sure if there are any cons to lowering it Cell 20 and Contrast 95, the set looks good but is a tad bright If using Contrast, say 75, during 10pt, adjustments at 9 affect 10, adjustments at 8 affect 9, and so on. Controls at 50 have little affect, then 1-4 act as they should. This AM, a THX calibrator, who just got a D8000, kept contrast at 95, and lowered Cell to 13, which gave him 35fL but allowed for 10pt to continue to work properly. This is a good idea, if wanting less light, unless there is something to Cell where it should not be lowered. Any thoughts?
