I am processing RAW images (.nef) from a Nikon camera. If I process these images in Adobe Lightroom I can adjust the highlights and shadows to avoid clipping any data. Histogram looks like this. 
In Mathematica, doing an Import with default values the ImageHistogram looks like this: 
Values appear to be clipped at both ends of the histogram. Applying ImageAdjust does not recover the data at the ends. It appears that importing a RAW file clips the data during the import process. The result is much like the defaults in Lightroom before adjusting the highlight and shadow sliders.
How can I import RAW images and get all the data without clipping?
