The PDF is trying to present a numbered pamphlet with 2 pamphlet pages per PDF page. There is also an option to number the navigation pages differently from the physical page of the PDF or the printed page numbers on the displayed page. Many older Nikon manuals do not have the Acrobat/Reader page number the same as the printed page number in the manual. They also tend not to bookmark, or link the Table of Contents and Index of the manual.
In the Nikon School class for NX2 the instructor demonstrated the use of sharpening to the eyes. He used High Pass for reflected surfaces like the eyes.
The use of D-Lighting and Shadow recovery can bring an incredible amount of detial out of shadows. I find the Shadow Recovery works well in Quick Adjust but the D-Lighting does not have enough control and works better in the Adjustment steps. Active D-Lighting is a good tool for high contrast situations but you have to remember to return it to your normal settings after use.
