I’m pretty happy with the image settings I came up with to make the D4 in-camera histogram approximate the real raw histogram. Using those settings, however, means not having the convenience of the D4’s exemplary automatic white balance. I guess I’ll use it with fixed white balance when I really care about getting the ultimate image quality, and with auto white balance when I want to minimize the time spent in Lightroom.
I still need to figure out if this trick works over a wide range of subject matter and lighting conditions. I also need to find out how transferable it is to other camera models.
