Quality, as you would imagine, is stunning (although a little disturbing, as with the picture of Bibi Aisha. The photograph makes the young girl look beautiful, such that you do not at first notice her obvious 'defect').
One also could wonder about the amount of post processing done at this level. How much of the final image is down to the camera, and how much to the PP software/graphics guys...
I would love to see the 'before' and 'after' shots...
