Lens Diffraction & Photography. Photo: airy disk with rings. "For an ideal circular aperture, the 2-D diffraction pattern is called an 'airy disk,' after its discoverer George Airy. The width of the airy disk is used to define the theoretical maximum resolution for an optical system (defined as the diameter of the first dark circle)." http://www.cambridgeincolour.com/tutorials/diffraction-photography.htm#calculator

hexagonal crystals create a halo around the moon. in optics it is called an airy disk and size due to diffraction of light. I was able to observe this about a week ago from my home town. beautiful

What You See Is What You Get!  These six cakes shed formality and happily flaunt their fillings. They’re great fun to put together -- and even more so to show off and share.

Really? A 41 megpixel camera on a phone? Are you on crack, Nokia?    http://gizmodo.com/5888552/reminder-megapixels-dont-matter

Reminder: Megapixels Don't Matter

When Nokia announced the Nokia Pure View 808 earlier in the year I knew I need to get my hands it.
