Media notes
Partial cross-section of humerus at mid-diaphysis. Overlapping photos (~50% overlap) of a portion of the cross-section were taken at 5x total magnification and through crossed Nicols filters, 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 CS5 Extended to remove the background, correct contrast (across the whole image), and to add text and a scale bar.
