It is a different file, just maybe too subtle of an adjustment. I just hesitate at going all the way to clipping since the original file looks pretty much the same as this.
I did carefully check the Blue channel in Raw as well as the Red and Green and strangely, there is no clipping on any of them in the higher highlights according to the curve and histogram data? Weird. Just some Red clipping in some redish areas. Although, yes the hot, almost whitish areas are rendered (as you can see here) with lack of detail. I just dont know that I can improve the look of the highlights. I appreciate the feedback though. That illusive perfection is always running away from me!!! 
For fun, because it probably doesn't help much, here is a 100% crop of the lower area, in Raw. According to ACR nothing is clipping except the Red channel in some Red areas, yet the upper highlights obviously lack some detail and appear very slightly yellow. I think maybe the camera is simply overwhelmed with what it is trying to shoot and it may just be a sensor rendering issue. Next time I'll try with the D800E or better......Show more →
First of all, the usual superlatives. You never disappoint, Mark.
I'm not experienced enough of a photographer to understand the situation you describe. I'm hoping others may know why histograms will show unclipped exposures that obviously have clipping. I'm supposing it is the limitations in range of the histogram. How does one compensate? Is it simply that clipping is unavoidable for some subjects -- the sun, lava?
Another question, Mark, about this shoot. Oddly enough, being a Seattleite and someone who has traveled extensively, I've never been to Hawaii. This is the context of the question. Is this area completely accessible? It seems there are enough safety issues that maybe it is not.
