[Note Guidelines] Photographer's Note
For this posting I have left the arctic and moved to a hot desert in Yemen - not that far from Ram in Saudi Arabia. I have posted this becuse I like the dunes, but also because it shows a typical sky in a sandy desert - white with a tinge of orange (from all the dust). I took this from the track(?) between the Queen of Sheba's capital at Marib and the desert city of Shibam.

A dune is a hill of sand built by eolian (wind) processes. Dunes are subject to different forms and sizes based on their interaction with the wind. Most kinds of dune are longer on the windward side where the sand is pushed up the dune, and a shorter "slipface" in the lee of the wind.

The "valley" or trough between dunes is called a slack. A "dune field" is an area covered by extensive sand dunes. Large dune fields are known as ergs - this is quite a small field - I saw some much bigger ones in Libya.

Crescent-shaped mounds are generally wider than they are long. The slipface is on the dune's concave side. These dunes form under winds that blow from one direction, and they also are known as barchans, or transverse dunes. Some types of crescentic dunes move faster over desert surfaces than any other type of dune. A group of dunes moved more than 100 meters per year between 1954 and 1959 in the People's Republic of China's Ningxia Province; similar rates have been recorded in the Western Desert of Egypt. The largest crescentic dunes on Earth, with mean crest-to-crest widths of more than 3 kilometers, are in China's Taklamakan Desert.

Hi James,
So it took you a year and 4 months to get to the desert from arctic :o) I like your POV, composition and the color tones. DOF is very good. So what is the next destination we'll see for tomorrow, a rainforest? TFS
Have a nice day

Hi James.
Sure is empty. I take it this is a vast space, bit hard to get a perspective of how vast it is. I like what you have done here with the patterns in the dunes, it seperates the shape of the dunes against all the one colour of sand,great image to go with your notes.

Hi James,
A superb picture, I love the red dunes; looks like a martian landscape! Sharpness and format are excellent. It's a bit tilted down to right or is a real effect?

Amazing Photo James.
Excellent composition. Very pure shot. Well done. tfs. Stev

Hi James. I didn't know there was a whole dune vocabulary! Thanks for the lesson. All that dust in the air makes me nervous for your lens and sensor. I suppose your lenses are pretty well sealed though. I was surprised at how much dust my zoom lens sucked in on my latest trip. Nice sharp shot and a great note...

Hi James,
Glad to see you switching between the icefields and the desert. Works for me. This photo captures the vastness of the desert so well. I like the panoramic format and the color. Your note is very well-written. Regards,
