[Note Guidelines] Photographer's Note
The real ruler of the desert is not Panthera leo but Oryx Gazella. The Gemsbok is the one animal designed by evolution to live in dry country. It can survive in some of the hottest locations on earth without water, owing to its unique natural air-conditioner that regulates the body’s temperature. They have a special blood cooling system just below the brain. The essence of this system is that blood going to the brain passes the carotid rete, a network of small, fine blood vessels. The blood returning to the heart is cooled by the breathing of air thru the sinuses. Thus, the blood reaching the brain is cooled by the blood returning to the heart. The Gemsbok also has the ability to lower or raise its body temperature, preventing it to sweat, and thereby loosing water. These features are not unique to the gemsbok, as other animals share them, but the gemsbok is the only one who combines the 2 attribute with such efficiency. It can slow its metabolic rate & lower its breathing rate to avoid moisture in its breath. It also extracts more moisture from its food than most other animals. It is both grazer & browser & feeds at night when grass absorbs some moisture from the air, as well as in the day. The magnificent set of V-shaped horns can reach a record length of 1,2 m or 48”. Body colour is pale greyish fawn overall, with white belly, legs & rump. The white face carries a black mask, as can be seen on the photograph - a beautiful, stately animal, true royalty!

Callie as usual a stunning portrait. The DOF is exceptional at F8 - Well taken

He's waiting for you till you captured him ?
He is looking like that: "Done, okay, I can go further".
Superb in "sharpness" and composition is very nice, good shot, Callie !

Wonderful posing you got from the gemsbok, Callie - gotta love those beautiful long horns, and the black mask on the face. Supreme detail and very good DOF, wonderfully done!

WoW, sharp sharp sharp. Nice portrait, I just love the earth tones in the background, you can feel the warmth.

A very nice detailed portrate Callie and even better notes .

I'll add my sentiments as well that this is a wonderful shot. The DOF coupled with the background color make the Oryx really pop. Super job!

Callie, great compo. The to get the DOF right with those horns... no mean feat. Another great contribution. Great note. Thanx.

Baie mooi skerp foto Callie. Ek hoor die Gemsbok is baie rats met daardie horings. Dit is darem maar een van ons merkwaardige bok soorte. Baie mooi geneem. Hier is regtig nie ruimte vir kritiek nie.
