Trying to apply what I learned from Jeff Schewe's book, when I use Lightroom to capture sharpen 12 MP pictures from a Nikon D700, I usually start with a radius of 0.5 for images with high frequency detail (landscapes or dog closeups for example), 1.0 for medium frequency, and 1.5 for low frequency (such as portraits). Is there any reason to increase those starting points when capture sharpening 36 MP images from a D800E since a given eyelash, pine cone, or whatever occupies more pixels? Should the radius be 3 times larger? 1.7 times (the increase in linear resolution)? I know there's no substitute for experience and good judgment, and there may not be any cookbook answers. Still, I would appreciate any information that might help improve my understanding of the theory on this point. Thanks.
