Hi Doug,

That is roughly what I end up with too, about 10 for black and 245-250 for white, most of the time anyway.

> PMFJI - for B&W, I always set the black and white points before messing with the middle slider.  I set the white point so that the brightest areas where I want detail are about 250 or so.  I'll let specular highlights such as sunlight reflecting off the water go to 255, so there's no fixed formula for where the white slider meets the histogram curve.  Similar for black point: I set the black slider so that the darkest areas that have detail are about 10, letting detail-less blacks go to zero if that's where they fall.  Once the black and white points are set I'll adjust the mid tones.
