This is only going to be a very short post. I have just begun processing pictures made during a week in Scotland with the D800. It was my first decent spell of landscape photography with the camera. As expected, the detail captured is astonishing. However, a less expected outcome of combining small apertures with such a highly resolving sensor is that it shows up every blemish on my aging filters. A fair amount of cloaning has been required to remove the telltale signs of filter abuse. I have a horrible feeling I'm going to have the expense of replacing my most often used 0.6 and 0.9 hard ND grads!
