One of the first things that I do when I begin to work on an image is to slide the black point and white point to the edge of clipping. With the DsMKII and DsMKIII and proper exposure I have never seen black points above about 5. A few days ago I shot numerous images of a Green Heron hunting for a snack. I used a 600 f4 / 1.4x TC / 1DsMKIII (normally I use this camera for sports). I shot images of other birds (Least Bittern posted on this forum) with the same setup. The Green Heron images were the only images that required the black point to be set as high as 54 before clipping occurred. Some of you are thinking AHA... over exposed. Not at all. In fact the white point slider was barely touched in every image (+.85 was the highest if I remember right). The histogram lacked data on both ends but was especially lacking on the left. When I followed my "normal" routine and adjusted for clipping and then backed up a tad the image looked "hyper-saturated". Almost cartoonish or painted. Backing the black point slider down to about 50% of the clipping value (25-30) helped the problem some but that's still a very high black point number.
I've fallen into the habit of post processing in ACR by the histogram and following up in CS3 by looking at the image. I suppose I need to change my habits some but this is the first time out of 10's of thousands of images that I've seen this.
Thoughts?
Here's an example (fairly tight crop)
