Media notes
Radial "transect" of the humerus at mid-diaphysis. Overlapping digital photos (~50% overlap) moving from the endosteal margin to the periosteal margin were taken at five points around the circumference. Photos were taken at 25x total magnification under regular transmitted light using a Nikon D300 DSLR camera attached to a Nikon Optiphot2-Pol light transmission microscope. Individual images were assembled into a photomontage of the entire section using Kolor Autopano Giga 2.0. The photomontage was then edited in Adobe Photoshop CS4 Extended to correct brightness and contrast (across the whole image) and to add text and a scale bar.
