Elephant

Nothing to shout about.  Just a character study on the details of this ele in the Aberdares.  Normally never do a square crop.  probably the first time ever here.  Just wanted to share some info.  The previous tusk shot shows some clear blue lines..  They are in the Cementum, the part of a tusk that cements the tusk to the jaw bone, hence its title.  The cracking we see and blue lines may only be shadow as the enamel  part is only at the tip, and the actual ivory lies under the cementum.  D3 and 300 F2.8 at Iso 400 and 1/640 F4.  was a vertical shot, ff, but showing the top only as per topic. 

naturally a click on the image shows it in more detail.
