A little clearer than the Waning Gibbous Moon shot from August. This moon announces the end of Summer 2007.

This photograph is a powerful representation of the waxing moon. The moon itself is a source of light reflecting the sunand in this concept the use of only lighting the moon is well placed. Also this is enhanced by the compsitional element of placing the moon central in the image. It is a successful portrayal by use of digital manipulation with a simple purpose that is conveyed to the point. The intention is simply to show the moon.
Thank you for your comments. I should mention that the digital manipulation of this image, beyond whatever processing occurred in the camera itself, is limited to a little bit of noise reduction and sharpening, cropping the image square, and adding the copyright notice.
Great shot - I'm "borrowing" it (with full credit to you) for a PowerPoint presentation to be given to a Cub Scout troop at Powell Observatory next Friday night.
To all of you leaving your wonderful comments, thank you very much. They are always greatly appreciated.

בדרך לבריכה מול גבעת ברנר ים פרגים 30 למרץ 2011

ים אדום של פרגים
אחרי הכלניות והצבעונים
כבשו הפרגים
(הנוריות גם מציצות אך לא במסות של הכלניות והפרגים)
שדות אדומים מוקפים בחגורות צהובות של חרציות

Frequently people land on this site with search queries like "what part of the eye corresponds to the camera shutter". With a camera, the shutter opens for a very precise amount of time and allows light to hit the film or sensor inside the camera. The closest comparison to that in the eye would be the eyelid that can open and close but its purpose is more analogous to that of the lens cap than the shutter. Shutter mechanisms come in a variety of configurations. More detailed information about camera shutters can be found in this article [Wikipedia].
Camera lenses also have a diaphragm iris [Wikipedia] which adjusts to increase or decrease the amount of the available light that can pass through it during any given period of time. This corresponds directly to the iris in the eye [Wikipedia] which serves the same purpose. I suspect many people confuse this with the diaphragm-type shutter mechanism, however both the eye's iris and that of the camera are visible through the lens while the shutter is generally inside the camera and out of sight. In modern cameras, the iris is usually fully open except at the moment when a picture is taken so it can be seen to move right about the same time as the shutter.
