You just don't blow out the sky. You know the drill: expose for the  
highlights, post process for the shadows. <g>

Of course I don't recall now if we were talking film or digital, but  
if shooting digital, push that histogram all the way to the right-- 
after experimentation to see when stuff really does start getting  
blown out. It's my understanding that the histogram you see on the  
back of the camera is generated from the in-camera .jpg, and does not  
necessarily closely relate to the actual RAW file. Without  
experimentation, it's not terribly reliable. I've messed with the D3  
enough now to pretty well tell when I've pushed to the limit. There is  
an incredible amount of information in those highlights that is  
recoverable with the proper post-processing approach.

And watch that "fake filter" talk, Bub. <g> ACR's graduated filter is  
no more fake than a piece of glass hung out in front of your lens.  
It's just different.
